HYDROCRACKING CATALYST COMPOSITION

摘要

PURPOSE:To provide the titled catalyst composition showing high cracking activity at a relatively low temp. and to conserve heat energy, by constituting the carrier of a hydrocracking catalyst from zinc oxide and aluminous oxide. CONSTITUTION:A catalyst carrier for hydrocracking a heavy stock oil consists of zinc oxide and aluminous oxide such as alumina or alumina-zeolite and an active metal consisting of a metal of the VII B group of the Periodic Table such as chromium and a metal of the VIII group such as iron or cobalt is carried by the aforesaid carrier. Because this catalyst composition shows high cracking activity at a relatively low temp. in carrying out hydrocracking, required heat energy is conserved as well as good quality light oil can be obtained in good yield.
