Heterogeneous Catalysis

The laboratory of air protection is equipped for research in the area of waste gas treatment processes using catalytic and adsorption based methods. The laboratory has equipment for gaseous sample collection, i.e. a system of passive dosing of gaseous samples, including an automated sampler cleaning system. The laboratory also provides service for gaseous mixture analysis. The laboratory does research and characterisation of gas phase heterogeneous catalysts for heterogeneous reactions, applied in the purification of waste gases from stationary sources both in industrial companies and in the laboratory. It also investigates adsorption and desorption process balance and kinetics. We offer testing of industrial catalysts, research of kinetics of catalytic reactions, modelling of reaction mechanisms, chemical engineering calculations, simulation and design of chemical reactors, determination of adsorption capacities of gases and vapours, and other research tasks, based on the customer's requirements.
