Technical Catalysis Group

Research and development on catalysts for many important large-scale processes of inorganic chemical industry are carried out in the Technical Catalysis Team. Work on these catalysts has above all an application aspect, i.e. research is carried out to improve the catalysts currently used in the industry or to work out a new kind of catalytic systems, which are more active than the commercially used catalyst. The second most important goal is the scientific aspect, that is knowledge about the nature of catalyst operation obtained through the extensive characterization of the prepared catalytic materials (applied techniques: TEM, SEM, XRPD, XPS, impulse chemisorption, static chemisorption, physisorption of N2, TG-MS, TPR, TPD and many others). Gaining additional information regarding the way the prepared catalysts function, lets us improve these catalytic systems, i.e. obtain catalysts with higher activity in the given reaction.

We are interested in catalysts for important industrial processes, such as:
• hydrodesulfurization
• water-gas shift reaction
• methanation of carbon oxides
• ammonia synthesis
• ammonia oxidation
• decomposition of nitrous oxide.

Among the equipment in the Laboratory of Technical Catalysis there is unique apparatus for measuring the reaction rate of the following processes: ammonia synthesis (in the range of elevated pressure, that is 100atm.), oxidation of ammonia, N2O decomposition, methanation of carbon oxides, ammonia decomposition. In addition, our group possesses a fully automated PEAK 4 instrument for characterization of catalysts by using temperature-programmed methods. It is used to estimate the dispersion of the metallic phase in the prepared materials. This parameter can also be determined by the static method by using ASAP 2020 (Micromeritics). This instrument is designed also for physisorption measurements at the temperature of liquid nitrogen (specific surface area, porosity, distribution of pore volume measurements). We also have a thermobalance equipped with a quadrupole mass spectrometer (STA 449; Netzsch). In the laboratory, there are many other less complicated instruments, which are necessary for the preparation procedures (among others: a vacuum evaporator, furnaces with controlled gas atmosphere).
