Process for converting an olefin containing hydrocarbon feed into an oligomerization product or a hydrogenated oligomerization product, comprising contacting the feed in a reactor with an oligomerization catalyst under conditions suitable to oligomerize the olefin to obtain an oligomerization product and optionally hydrogenating the oligomerization product wherein the content of the at least one C-, C-, C- or C-cyclic olefin in the feed is controlled.

Olefin oligomerization in the presence of cyclopentene

Embodiments of an invention disclosed herein relate to processes utilizing solvent extraction to remove nitrogen containing compounds and optionally other components from feedstreams of olefins and paraffins.

Processes utilizing solvent extraction

The conversion and run length for oligomerization of olefins over a molecular sieve catalyst in a tubular reactor is improved by controlling the peak temperature to not exceed 50 degrees C. above the temperature of the temperature control fluid exiting the shell side outlet of the reactor. A tubular reactor containing molecular sieve catalyst is provided with a multipoint thermocouple in at least one tube, and optionally with a bottom design adapted for fast unloading of the molecular sieve catalyst from the tubular reactor.

Oligomerisation of olefins with zeolite catalyst

Sulphur-containing olefinic feedstocks are oligomerized over zeolite catalysts.

Oligomerization and catalysts therefor

Limiting the sulphur level in olefin feedstocks to zeolite-catalysed oligomerization enhances selectivity to trimer and catalyst life and activity.

Olefin oligomerization

Limiting the sulphur level in olefin feedstocks to zeolite-catalysed oligomerization enhances selectivity to trimmer and catalyst life and activity.
