New bifunctional Ni–H-Beta catalysts for the heterogeneous oligomerization of ethylene

•Bifunctional Ni-Beta catalysts are active and stable in ethylene oligomerization.•Ni sites predominantly produce butenes and, to a lesser extent, hexenes and octenes.•Branched C5+ alkenes formed by secondary oligomerization on Brønsted acid sites.•Based on CO-FTIR, Ni2+ cations at exchange sites ar...
