C4 C5 C6 PREPARING METHOD OF LUBE BASE OIL USING C4 C5 C6 STREAM

摘要

The present invention relates to a method for manufacturing a lubricating base oil using C4, C5, C6 streams, specifically, naphtha catalytic cracking (NCC), heavy oil upgrading process, thermal cracking, or fluid catalytic cracking. Preparing C4, C5, C6 streams that are products of the process (FCC or RFCC); Generating a branched hydrocarbon by carrying out an oligomerization reaction or an alkylation reaction of the C4, C5, C6 stream using an acid catalyst; By including the step of mixing the produced branched hydrocarbon and low-cost hydrocarbon, it relates to a method for producing a lubricating base oil using a C4, C5, C6 stream.
