METHOD AND SYSTEM FOR HYDROCRACKING

WIPO Patent Application WO/2023/040890

A1

A method and system for hydrocracking. A wax oil raw oil and a hydrogen mixture are first subjected to contact reaction by means of a hydrotreating unit, and then a reaction effluent enters a first hydrocracking unit to react with a hydrocracking catalyst I to obtain a light fraction I enriched in paraffin hydrocarbon and a heavy fraction I enriched in cyclic hydrocarbon, and the heavy fraction I is mixed with hydrogen and then enters a second hydrocracking reaction unit for reaction, so as to obtain a heavy fraction II enriched in cyclic hydrocarbon.
