The authors develop a carrier for catalysing the pyrolysis of petroleum products which possesses outstanding catalytic properties. Granular ceramic was the carrier material; the main components are alumina and silica. The starting materials for making the carrier consist of granular electrocorundum and Prosyanovsk kaolin. The highest yield of ethylene and the lowest yield of coke were obtained on carriers made from corundum and mullite. The catalyst was made by preparing the carrier with impregnation of the active body KVO/sub 3/ and with the promoter H/sub 3/BO/sub 3/, dried at 90/sup 0/ C, and then calcined. 3 Analysis shows that the best properties are possessed by specimens of catalysts prepared on carriers with 20% kaolin. Industrial use of catalytic pyrolysis will significantly improve savings of raw materials as a result of increasing the ethylene yield 1.3-1.4 times.
