C2 C3 PROCESS FOR PRODUCING C2 AND C3 HYDROCARBONS

摘要

The present invention relates to a process for the production of C2 and C3 hydrocarbons,a) performing a first hydrocracking in the mixed hydrocarbon stream in the presence of a first hydrocracking catalyst to produce a first hydrocracked product stream; Andb) subjecting the first hydrocarbon product stream to C4 hydrocracking optimized to convert C4 hydrocarbons to C3 hydrocarbons in the presence of a C4 hydrocracking catalyst to obtain C4 hydrocracking products comprising C2 and C3 hydrocarbons.
