An integrated process for production of jet-fuel range olefins from ethylene using Ni-AlSBA-15 and Amberlyst-35 catalysts

•An integrated process for production of jet-fuel range olefins from ethylene was developed.•Ethylene was first oligomerized to C8+-rich olefins over the bifunctional Ni-AlSBA-15 catalyst.•The liquid-phase C8+-rich olefins were co-oligomerized to C10+-rich olefins over Amberlyst-35.
