Abstract

Butene-2 oligomerization to chemical feedstocks is investigated over ZSM-5 catalysts with varying silica-to-alumina ratio and compared with the performance over silica-supported phosphoric acid (SSPA). Butene-2 is oligomerized more efficiently at 4 MPa and 1 hr⁻¹ over ZSM-5 zeolite with liquid yield ≥66.6%, selectivity to heavy product ≥54.5%. The products over ZSM-5 are also less branched.
