摘要： A feed mixture comprising at least one C3 olefin and/or at least one C4 olefin 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 C12 olefins in the product mixture having an average branching index of about 2.2 or less. Under suitable conditions, C10-C13 olefins may comprise at least about 25% of the product mixture, M based on total olefin oligomers. Percentage conversion of the at least one C3 olefin and/or at least one C4 olefin may impact the average branching index of at least C12 olefin oligomers and selectivity for C10-C13 olefin oligomers. An amount of C4 olefin in the feed mixture may produce a targeted selectivity for at least C1 olefins.

摘要： A feed mixture comprising at least one C3 olefin and/or at least one C4 olefin 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 C12 olefins in the product mixture having an average branching index of about 2.2 or less, such as about 1.3 to about 2.0. Under suitable conditions, C10-C13 olefins may comprise at least about 25% of the product mixture, based on total olefin oligomers. Percentage conversion of the at least one C3 olefin and/or at least one C4 olefin may impact the average branching index of C12 olefin oligomers and selectivity for C10-C13 olefin oligomers. An amount of C4 olefin in the feed mixture may produce a targeted selectivity for C12 olefins.
