Abstract
In a process for the oligomerization of C.sub.2 -C.sub.12 -alkenes, an alkene-containing feedstock having a water content of from 0.05 to 0.25 molar %, based on the hydrocarbon content of the feedstock, is passed over a zeolite catalyst. Improved alkene conversion and catalyst life are obtained compared to processes in which non-hydrated feedstocks are used.
Claims8
A process for oligomerising C.sub.2 -C.sub.12 -alkenes to produce olefins of initial boiling point in the range 30.degree. to 310.degree. C., comprising contacting a C.sub.2 -C.sub.12 -alkene-containing feedstock having a water content of from 0.05 to 0.25 molar %, based on the hydrocarbon content of the feedstock, with a zeolite structure catalyst selected from the group consisting of TON, MTT, MFI, MEL, MTW, EUO, H-ZSM-57, ferrierites, offretites, H-ZSM-4, H-ZSM-18, Zeolite Beta, faujasites, zeolite L, mordenites, erionites and chabazites.
