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.

Systems and methods are provided for production of high octane hydrocarbon from an isoparaffin feed using oxidation 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 C.sub.8+ olefins (e.g. isooctene). A catalyst having an MWW framework is an example of a suitable solid acid catalyst.

Methods and systems for converting hydrocarbons including exposing a portion of a hydroperoxide-containing feed including tert-butyl hydroperoxide to a solid deperoxidation catalyst under decomposition conditions to form an oxidation effluent comprising tert-butyl alcohol, wherein the solid deperoxidation catalyst comprises a manganese oxide octahedral molecular sieve, are provided herein. Further methods and systems for converting the oxidation effluent to an alkylation product are also provided herein.
