Combination of olefin oligomerization and paraffin alkylation

摘要

In a process for alkylating C4-C18 alkenes in the presence of an acid catalyst, propylene is separated from the alkenes feed, the propylene is oligomerized to oligomers containing maily propylene tetramers, and the propylene oligomers are then combined with the remainder of the alkene feed before the alkylation reaction is carried out.
