Isobutanol may be converted into predominantly Colefin oligomers under specified conditions. Such methods may comprise: contacting a feed comprising isobutanol with a zeolite solid acid catalyst having a MWW framework under conditions effective to convert the isobutanol into a product comprising Colefin oligomers, wherein n is an integer having a value of two or greater and about 80 wt. % or greater of the Colefin oligomers are larger than C.

Oligomerization of isobutanol in the presence of MWW zeolite solid acid catalysts

Systems and methods are provided for production of high octane hydrocarbon from an isoparaffin feed using oxidation acid catalysis chemistry.

Production of high octane hydrocarbon from light alkane feed using oxidation and acid catalysis chemistry

Systems and methods are provided for forming alkylate from a tertiary alcohol feed. Olefins for the alkylation reaction can be generated from a portion of the tertiary alcohol feed. The tertiary alcohol feed can be obtained, for example, by selective oxidation to convert a portion of an isoparaffin-containing feed into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate dimerization of the alkenes (e.g. isobutene) to form Colefins (e.g. isooctene). A catalyst having an MWW framework is an example of a suitable solid acid catalyst.

Production of iso-octene from tertiary alcohols

Systems and methods are provided for forming alkylate from an isoparaffin-containing feed. Olefins for the alkylation reaction can be generated from a portion of the isoparaffin-containing feed. This can be achieved, for example, by using selective oxidation to convert a portion of isoparaffins into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate alkylation of isoparaffin using the in-situ formed alkenes. A catalyst having an MWW framework is an example of a suitable solid acid catalyst.
