Abstract
A novel catalyst composition and its use in the oligomerization reaction converting a portion of a C4 to C5+ alkene feed stream to C4 to C6+ olefin derivatives. The catalyst comprises a Group VIII metal selected from the group consisting of nickel, iron, cobalt, and combinations thereof, on a support. The support can be silica, silicon dioxide, titanium dioxide, metal modified silica, silica-pillared clays, silica-pillared micas, metal oxide modified silica-pillared mica, silica-pillared tetrasilicic mica, silica-pillared taemolite, zeolite, molecular sieve, and combinations thereof. The catalyst composition is an active and selective catalyst for the catalytic oligomerization of alkenes to olefins and olefin derivatives.
