Abstract
The invention is directed to a method of selectively oligomerizing olefin monomers by controlling feedstock composition and reaction conditions. Reaction conditions are chosen to include at least one of: (a) dimer recycle; (b) staged injection of monomer; and (c) utilization of a two catalyst system.
Claims21
A process for upgrading light olefins to higher olefins comprising contacting a feed comprising at least one olefin monomer selected from C3-C5 olefins and a dimer of said at least one monomer with at least one zeolite oligomerization catalyst under oligomerization conditions in at least one reactor and recovering a trimer of said at least one olefin monomer.
