Abstract:
A process for producing a synthetic hydrocarbon product, the process comprises contacting under isomerization conditions an olefin feed and a catalyst,wherein at least 50% of the olefin feed is comprised of linear olefins containing at least 12 carbon atoms, andwherein the catalyst consists of either a zeolitic molecular sieve with oval, one-dimensional pores having a minor axis between about 4.2 A and about 4.8 A and a major axis between about 5.4 A and about 7.0 A or a non-zeolitic molecular sieve with a non-aluminum metal which forms oxide linkages in tetrahedral coordinates with aluminum and phosphorous in a crystalline framework, andwherein the catalyst is free of noble or transition metals, andwherein the isomerization conditions are such that there is at least 5 weight % skeletal isomerization of the carbon backbone and the isomerization conditions include a temperature in the range of from 100.degree. C. and 200.degree. C., andwherein the product comprises a mixture of branched olefins and linear olefins.
