Fuel compositions comprising isoprene derivatives

摘要

Methods, compositions and systems using isoprene from a bioisoprene composition derived from renewable carbon for production of a variety of hydrocarbon fuels, fuel additives, and additives for fine chemistry and other uses is described.

1. A method for producing a fuel constituent from a bioisoprene composition comprising chemically transforming a substantial portion of the isoprene in the bioisoprene composition to one or more non-isoprene compounds by:
(a) contacting the bioisoprene composition with a catalyst for olefin metathesis to produce one or more olefin products and then catalytically hydrogenating the one or more olefin products to form one or more alkane fuel constituents; (b) partially hydrogenating the bioisoprene composition to produce an isoamylene and then alkylating the isoamylene with an isoparaffin to form a high octane alkylate fuel constituent; or (c) partially hydrogenating the bioisoprene composition to produce one or more isoamylenes, then contacting the one or more isoamylenes with a catalyst for olefin metathesis to form one or more olefin products, and then catalytically hydrogenating the one or more olefin products to form one or more alkane fuel constituents.
