CATACON CATACON CATACON CATACON CATACONGROUP OF CATALYSTS TESTINGThe group of catalysts and supports testingperforms: comparison and lifetime tests, studiesof catalytic process kinetics and catalysts activityin the catalysts deactivation processes, tests oflaboratory samples, experimental batch catalystsamples and commercial samples (fresh andunloaded from commercial setups).An approach to control of catalytic properties isprimarily determined by the fact that catalysis isa kinetic phenomenon which is associated withan increase of chemical reaction rates undercatalysts action. For this reason, it is reasonableto use specific rate of a chemical reactioncalculated per unit catalyst volume (weight,volume, surface) as a criterion of catalyticactivity.The flow-circulating method involving differentmodifications and improvements of schematicdiagrams of a technological setup, associatedwith process peculiar features, is the mostpromising method of determining catalystsCatalytic processes performed on the setup of the departmentAmination of aromaticsNOx reduction by ammonia and syngasSÎ2 reduction by methaneGas-phase nitration of aromaticsHydrocrackingHydrolysis of COS and HCN during cleaning of syngasOxidation of binary liquid hydrocarbonsOxidative dimerization of methaneOxidation of hydrocarbons, ammonia, sulfur dioxide, hydrogen sulfideOxidative ammonolysis of propane (propylene) into acroleinPurification of ethylene (propylene) from acetylene fractionsSteam and air reforming of methaneDehydrogenation of hydrocarbonsFischer-Tropsch processSteam conversion and oxidation of ÑÎSteam reforming of methanol (ethanol)Synthesis of ammonia, methanol, vinyl acetateSynthesis of unleaded gasoline from gas condensate and by-products of oil refiningTests are performed in the setups supplied with reactors, 1 to 100 ml in volume, at atmospheric pressure andunder conditions of increased pressure (to 100 bar) and maximal temperatures as high as 850 CThe reactor designs allow investigations of granules of commercial catalysts as well as honeycombcatalysts reinforced with a stainless steel net or their fragmentsTo obtain reliable data on catalyst activity, we use differential reactors with an externalsteam-gas mixture circulation
