CATALYSTIC HYDROCRACKING CATALYST FOR HEAVY HYDROCARBON AND CATALYSTIC HYDROCRACKING METHOD USING IT

摘要

PURPOSE:To provide a catalyst capable of producing less gaseous hydrocarbon and much light to intermediate oil, and converting all asphalten and preasphalten in a raw material into light-to-intermediate oil and cokes, and to provide a catalystic hydrocracking method of heavy hydrocarbon using the catalyst. CONSTITUTION:One or more metals selects from group VIII of the periodic table are deposited on a carbon carrier obtained by activating coked coal which is obtained by dry distilling brown coal with <=3wt.% ask content at 400-800 deg.C in a CO2 atmosphere at 600-900 deg.C in a CO2 or steam atmosphere and later reduced with hydrogen and consequently sulfide treatment is performed, thus the catalystic hydrocracking catalyst for heavy hydrocarbon is obtained and the catalystic hydrocracking method of heavy hydrocarbon using the catalyst is provided.
