Catalytic setups are designed to examine catalytic properties of new catalysts, based on metal oxides, silicas and carbon materials, in dehydrogenation of hydrocarbons or total oxidation of volatile organic compounds. Essential elements of each system are: (i) a reagent dosing system, including gas lines with gas flow controllers, and a scrubber containing liquid reagent, kept at an appropriate temperature, (ii) quartz microreactor with a tested catalyst bed, placed in an oven, controlled by a control unit, and (iii) a detector for qualitative and quantitative analysis of catalytic reaction products based on a gas chromatograph (Bruker 450-GC) or a quadrupole mass spectrometer (PREVAC). The Bruker 450 gas chromatograph is equipped with two capillary columns (for example Porapak Q, MolSieve 5A, Chromosorb W-HP), two flame ionization detectors, a thermal conductivity detector and methanizer. The reaction products are collected using a pneumatic valve and analyzed on-line in the gas gromatograph automatically.
