Abstract
A feed mixture comprising at least one Colefin and/or at least one Colefin may be contacted with a zeolite catalyst under oligomerization reaction conditions to form a product mixture comprising a plurality of olefin oligomers. The zeolite catalyst, optionally with one or more further modifications, may be selected for operability at high WHSV values that may produce at least Colefins in the product mixture having an average branching index of about 2.2 or less. Under suitable conditions, C-Colefins may comprise at least about 25% of the product mixture, M based on total olefin oligomers. Percentage conversion of the at least one Colefin and/or at least one Colefin may impact the average branching index of at least Colefin oligomers and selectivity for C-Colefin oligomers. An amount of Colefin in the feed mixture may produce a targeted selectivity for at least Colefins.
