Abstract
The present disclosure relates to a method for upgrading hydrocarbon using C4, C5 and C6 streams, and more specifically, to a method for upgrading hydrocarbons using C4, C5 and C6 streams. The method includes the steps of: preparing C4, C5 and C6 streams, which are the products of naphtha catalytic cracking (NCC) process, heavy oil upgrading process, thermal cracking process, or fluidized catalytic cracking (FCC or RFCC) process; oligomerizing the C4, C5 and C6 streams with a catalyst to produce branched unsaturated hydrocarbons; and fractional distillating the branched unsaturated hydrocarbons to separate into C14-18 products or C32-40 products.
Claims5
A method for oligomerizing C4, C5 and C6 hydrocarbon streams comprising:
- preparing C4, C5 and C6 hydrocarbon streams in a Residue Fluidized Catalytic Cracking (RFCC) process;
- oligomerizing the C4, C5 and C6 hydrocarbon streams with a catalyst to produce branched unsaturated hydrocarbons;
- separating the branched unsaturated hydrocarbons in a fractional distillation column to separate a first fraction comprising C14-C18 branched unsaturated hydrocarbons and a second fraction comprising C32-C40 branched unsaturated hydrocarbons;
- and
- subjecting the C32-C40 branched unsaturated hydrocarbons in the second fraction to aromatic alkylation at a temperature of 150 to 350° C. to produce a second alkylaromatic product having a pour point of less than −50° C.
