Embodiments of an invention disclosed herein relate to particles made from zeolite catalysts and their use in oligomerization processes. In particular, extrudates having an average particle size of from 1.6 mm (about 1/16th inch) or less or, alternatively, from 1.3 mm (about 1/20th inch) or less are made from compositions including the product of at least one zeolite catalyst and at least one binder. The extrudates may be shaped particles, for example, multilobe extrudates.

In a feed clean-up process at least two adsorbents (2, 4)are installed in front of an oligomerization reactor(3). Olefin feed is sent over one adsorbent (2) and the nitrile poisons are adsorbed so that clean feed will enter the reactor (3). Before the adsorbent (2)will be saturated, the feed (1) is sent to the other, fresh adsorbent (4). At the same time oligomerization product from the reactor (3) is used to desorb nitriles from the spent adsorbent (2).

The invention relates to an olefin oligomerization process comprising the steps of: i) contacting a feed comprising olefins and nitrileswith a guard bed comprising eta alumina; and ii) contacting the feed obtained in step i) with an oligomerization catalyst under conditions suitable to oligomerize the olefins in the feed. It also relates to the use of a guard bed comprising eta-alumina for reducing the content of basic organic compounds in a hydrocarbon feed.

The present invention relates to an olefin oligomerization process, a catalyst composition, a method for producing the catalyst composition and the use of such catalyst composition in olefin oligomerization.

In a process for oligomerizing an olefinic hydrocarbon feedstock comprising at least 65 wt % olefins and/or sulfur-containing molecules, the feedstock is contacted under oligomerization conditions with (a) a first unidimensional 10-ring molecular sieve catalyst and (b) a second multidimensional crystalline molecular sieve catalyst. The first and second catalysts may be contained in separate reactors or as separate beds in a single reactor.

The invention provides an olefin oligomerization process comprising the steps of: i) reducing the level of nitriles in an olefin feed by contacting the feed with a guard bed comprising gamma alumina having a surface area greater than 250 m2/g; and ii) contacting the olefin feed obtained in step i) with an oligomerization catalyst under conditions suitable to oligomerize the olefins in the feed; wherein the gamma alumina used in step i) has been obtained from needle shaped boehmite.
