Title: Catalysis Engineering, a Multi-level Approach

Abstract:

Catalysis plays an important role in Chemical Process technology. It is the enabling technology for good chemical manufacturing processes. Catalysis as a discipline is not just a part of chemistry or physics but it also is an engineering discipline. Chemical and physical aspects are often scale-independent but in the engineering disciplines usually, the scale of the operation plays a role. In catalysis, both scale- independent and scale-dependent phenomena play a role. The reaction mechanism and structure of the active sites are usually scale-independent. Reactor design studies belong to the realm of chemical reaction engineering and are clearly dependent on the scale. In catalysis good contact between reactants and active sites is essential and the contact is, in general, scale-dependent. An integrated approach of catalysis research and development covering aspects of (bio) chemistry and physics and chemical reaction engineering, referred to as ‘Catalysis Engineering ‘, is rewarding. It is appropriate to distinguish three levels, the microlevel, focusing on molecules and catalytic sites, the mesolevel focusing on the catalyst particle and the reactor, and the macro level, considering the total process. This lecture focuses mainly on multiphase (G/L) systems.

On the microlevel, the scale-independent information is collected. Thermodynamics defines the possible window of operation and heats of reaction. Information on kinetics is crucial. On the mesolevel, fascinating developments are visible in the field of structuring the space. On the one hand, at the scale of the particle, optimal porosity (optimal hierarchal pore networks consisting of micro-, meso- and macropores) is important. On the other hand, structured reactors often outperform conventional reactors such as packed bed reactors. Pros of fixed bed reactors are high catalyst loading, convenience, low cost and often the possibility to use commercially available catalysts; cons are maldistribution, leading to non-uniform concentration profiles and even hot spots, internal diffusion limitations that might lead to reduced activity and selectivity. In a packed bed reactor hydrodynamics and mass transfer rates are coupled to particle shape and size. In a structured reactor, more degrees of freedom exist. For instance, dependent on the design, particle sizes can be chosen to be much smaller than those in packed beds. Structured reactors allow a high efficiency, based on a high mass transfer rate at relatively low energy dissipation. The low energy dissipation is related with the hydrodynamics regime: laminar rather than turbulent. In addition, in multiphase flow under most practical conditions, the flow pattern is that of segmented flow (called Taylor flow), resulting in large gas-liquid mass transport rates. Structured reactors have a large potential in Process Intensification. From a chemical engineering point of view, the intrinsic scalability of these reactors is intriguing.

It is not wise to carry out the research aimed at developing a good catalyst separately from the reactor design. It does not make sense to develop the best possible catalyst and to use it in an unsatisfactory reactor. Both the catalyst and the reactor should be optimal. In addition, it does not make sense to develop a catalyst and reactors without attention to the macro- level. In all stages of process development or improvement, the (conceptual) process design should play a role.

The benefits of a multi-level approach will be illustrated with practical examples.

Title: Conventional vs. Microwave Heating in Combustion Synthesis of Ca-Mn Perovskite Used in MgO Nanocatalyst for Biodiesel Production

Abstract:

In the present article, MgO/Ca₂Mn₃O₈ nanocatalyst was used in the transesterification process for production of green fuel from sunflower oil. Besides, the synthesis of the layered nanostructured Ca₂Mn₃O₈ support was carried out by combustion method. The effect of two heating approaches including muffle furnace and microwave irradiation was investigated on the characteristics of calcium-manganese mixed oxide used as the support of the MgO active phase. Both of the synthesized nanocatalysts were characterized by different techniques such as XRD, FESEM and EDX. The nanocatalyst produced by the microwave irradiation combustion method scored the best performance. This nanocatalyst had the highest specific surface area (46.39 m²/g), and better pore volume distribution, too. It was also found that the nanocatalyst converted 96.7% of sunflower seed oil to fatty acid methyl esters (FAMEs), and exhibited better reusability in the same operating conditions compared to the sample synthesized with muffle furnace in five runs. This justified the positive influence of microwave irradiation on the catalytic properties.

Title: Constructing of ultrathin 2D material for highly efficiency electrocatalysis

Biography: Two dimensional materials possess inherent advantages to improve electrocatalytic performance. First, two dimensional nanosheets have large surface–volume ratio, which can promote the adsorption of substrates and provide high specific surface area for electrocatalytic reactions. Moreover, the 2D nature of the nanosheets indicates short diffusion distance for electrons, which causes faster charge transfer rate and better turnover frequency. Therefore, Constructing of 2D ultrathin nanosheets is an effective strategy to achieve high electrocatalytic performance. Our group recently reported a series of 2D ultrathin materials: (1) Bimetal ultrathin metal-organic frameworks (MOFs) nanosheets were successfully prepared through a simple ultrasonic oscillation method. Due to the ultrathin feature, the surface metal atoms are highly coordinated unsaturated, which greatly benefit the adsorption process, thus offering outstanding performance. Besides, two kinds of metal atoms could generate the coupling pair, which could effectively promote the charge transfer.1 (2) On the basis of ultrathin nanosheets, novel 3D flower-like Ni2P were synthesized through the self-assembly of ultrathin Ni2P nanosheets, which retain the 2D structural advantages and offer faster electrons transfer compared with dispersed unassembled 2D nanosheets.2 (3) To further optimized the catalytic performance, 3D porous core-shell ultrathin nanosheets were prepared via a facile stepwise hydrothermal method. The ingenious architecture possess numerous channels for the diffusion of substrates, ideal pathway for electron transfer and larger area for adsorption compared with imporous nanosheets. Collectively, our constructing strategy provided a successful practice to prepare a series of high-efficient catalysts.

Therefore, Constructing of 2D ultrathin nanosheets is an effective strategy to achieve high electrocatalytic performance. Our group recently reported a series of 2D ultrathin materials: (1) Bimetal ultrathin metal-organic frameworks (MOFs) nanosheets were successfully prepared through a simple ultrasonic oscillation method. Due to the ultrathin feature, the surface metal atoms are highly coordinated unsaturated, which greatly benefit the adsorption process, thus offering outstanding performance. Besides, two kinds of metal atoms could generate the coupling pair, which could effectively promote the charge transfer.1 (2) On the basis of ultrathin nanosheets, novel 3D flower-like Ni2P were synthesized through the self-assembly of ultrathin Ni2P nanosheets, which retain the 2D structural advantages and offer faster electrons transfer compared with dispersed unassembled 2D nanosheets.2 (3) To further optimized the catalytic performance, 3D porous core-shell ultrathin nanosheets were prepared via a facile stepwise hydrothermal method. The ingenious architecture possess numerous channels for the diffusion of substrates, ideal pathway for electron transfer and larger area for adsorption compared with imporous nanosheets. Collectively, our constructing strategy provided a successful practice to prepare a series of high-efficient catalysts.

Title: Catalysis Engineering, a Multi-level Approach

Abstract:

Catalysis plays an important role in Chemical Process technology. It is the enabling technology for good chemical manufacturing processes. Catalysis as a discipline is not just a part of chemistry or physics but it also is an engineering discipline. Chemical and physical aspects are often scale-independent but in the engineering disciplines usually, the scale of the operation plays a role. In catalysis, both scale- independent and scale-dependent phenomena play a role. The reaction mechanism and structure of the active sites are usually scale-independent. Reactor design studies belong to the realm of chemical reaction engineering and are clearly dependent on the scale. In catalysis good contact between reactants and active sites is essential and the contact is, in general, scale-dependent. An integrated approach of catalysis research and development covering aspects of (bio) chemistry and physics and chemical reaction engineering, referred to as ‘Catalysis Engineering ‘, is rewarding. It is appropriate to distinguish three levels, the microlevel, focusing on molecules and catalytic sites, the mesolevel focusing on the catalyst particle and the reactor, and the macro level, considering the total process. This lecture focuses mainly on multiphase (G/L) systems.

On the microlevel, the scale-independent information is collected. Thermodynamics defines the possible window of operation and heats of reaction. Information on kinetics is crucial. On the mesolevel, fascinating developments are visible in the field of structuring the space. On the one hand, at the scale of the particle, optimal porosity (optimal hierarchal pore networks consisting of micro-, meso- and macropores) is important. On the other hand, structured reactors often outperform conventional reactors such as packed bed reactors. Pros of fixed bed reactors are high catalyst loading, convenience, low cost and often the possibility to use commercially available catalysts; cons are maldistribution, leading to non-uniform concentration profiles and even hot spots, internal diffusion limitations that might lead to reduced activity and selectivity. In a packed bed reactor hydrodynamics and mass transfer rates are coupled to particle shape and size. In a structured reactor, more degrees of freedom exist. For instance, dependent on the design, particle sizes can be chosen to be much smaller than those in packed beds. Structured reactors allow a high efficiency, based on a high mass transfer rate at relatively low energy dissipation. The low energy dissipation is related with the hydrodynamics regime: laminar rather than turbulent. In addition, in multiphase flow under most practical conditions, the flow pattern is that of segmented flow (called Taylor flow), resulting in large gas-liquid mass transport rates. Structured reactors have a large potential in Process Intensification. From a chemical engineering point of view, the intrinsic scalability of these reactors is intriguing.

It is not wise to carry out the research aimed at developing a good catalyst separately from the reactor design. It does not make sense to develop the best possible catalyst and to use it in an unsatisfactory reactor. Both the catalyst and the reactor should be optimal. In addition, it does not make sense to develop a catalyst and reactors without attention to the macro- level. In all stages of process development or improvement, the (conceptual) process design should play a role.

The benefits of a multi-level approach will be illustrated with practical examples.

Title: Optimization of Spent Caustic Wastewater Treatment of Jam Petrochemical Company by Wet Air Oxidation (WAO) method

Abstract:

Spent Caustic comes from a variety of sources. In these streams, sulfides and organic acids are removed from the production stream by transferring to the caustic phase. Hydrogen sulfide is consumed and the waste produced is usually a mixture of materials, which is referred to as the Spent Caustic Refinery. This wastewater cannot be recycled using conventional wastewater treatment methods, and methods such as burning, humidifying oxidation, wet oxidation by hydrogen peroxide and electrocoagulation or other specialized processes are used. In this study, the method of wet oxidation by air was used to purify this effluent in Jam Petrochemical Company. In order to optimize the purification, important factors influencing the purification efficiency were investigated, including factors such as temperature, pressure, time and pH. The design of optimization experiments was done by Design Express software. The optimization results showed that the temperature had the most effect on the removal efficiency, after which the pH and time had the most effect, respectively, and the effect of the pressure was not significant. Also, the parameters of pressure and time, time and pH had a significant interaction. In particular, the maximum removal rate (87%) was achieved for temperature of 250 ° C, 62 minutes, with pH 7 and 6 bar pressure.

Title: Ultrasound Assisted Dispersion of Magnesium Oxide on CeMCM-41 Nanocatalyst for Biodiesel Production from Waste Vegetable Oil

Abstract:

In this study, Mobil Composite Material No. 41 (MCM-41) used as the catalyst support for biodiesel production from waste cooking oil. Also, Si/Ce molar ratio of 10 introduced to the MCM-41 structure to prepare a modified bifunctional nanocatalyst with high stability and acidity. Then, ultrasound irradiation used to disperse MgO as active phase on the surface of as-fabricated support. The synthesized nanocatalysts were investigated using various techniques as follows: XRD, TEM, FESEM, and BET. The XRD patterns along with the results of BET analysis revealed the MCM-41 framework destruction while introducing Ce into the lattice. The particle size and size distribution of the nanocatalyst with Si/Ce=10 were subsequently determined by TEM and FESEM images. Biodiesel production carried out under following operational parameters to evaluate the catalytic performance of synthesized samples: T=70°C, catalyst loading=5 wt. %, methanol/oil molar ratio=9, and 6 h reaction time. Ce substitution in the support framework considerably enhanced the biodiesel conversion. The nanocatalyst with Si/Ce=10 demonstrated the extraordinary conversion of 94.3% compared to the nanocatalyst without Ce with 9.1% conversion. The reusability of the nanocatalyst with Si/Ce=10 studied during seven reaction cycles and biodiesel conversion reached to 88.7% at the end of the last cycle which demonstrates its significant stability.

Title: Photocatalytic Elimination of Antibiotic Ofloxacin over Plasmonic AgBr Anchored with Co-Cr Layered Double Hydroxide as Solar-Light-Driven Nanophotocatalyst

Abstract:

Currently, antibiotics, as non-biodegradable and emerging contaminants, are recognized as one of the most important environmental challenges. Photocatalysis process is an effective method for the degradation of resistant contaminants due to the low-cost and eco-friendly. In this study, the elimination of the antibiotic ofloxacin was investigated using the novel plasmonic AgBr anchored with Co-Cr layered double hydroxide (denoted as: AgBr-CoCrLDH-P) nanophotocatalyst with 3:1 weighted ratio under simulated sunlight, and to further evaluate, pure AgBr-P and CoCrLDH samples were synthesized and employed in the ofloxacin degradation. For 25 mg/L ofloxacin solution, the photocatalytic efficiency of CoCrLDH, AgBr-P and AgBr-CoCrLDH-P after 120 min irradiation was found 11.4%, 65% and 83.6%, respectively. XRD and FESEM analysis were used to characterize the photocatalysts. According to the results, the AgBr-CoCrLDH-P nanocomposite exhibited significantly enhanced photocatalytic performance due to a large specific area, low band gap and good charge separation.
