Butanol compositions for fuel blending and methods for the production thereof

摘要

The invention relates to butanol compositions for fuel blending and fuel blends comprising such compositions. The compositions and fuel blends of the invention have desirable performance characteristics and can serve as alternatives to ethanol-containing fuel blends. The invention also relates to methods for producing such butanol compositions and fuel blends.

主权项

1. A process for producing a butanol composition for fuel blending comprising:
providing a butanol stream primarily including butanol, an octane improving component stream primarily including the octane improving component, and a vapor pressure adjustment component stream primarily including the vapor pressure adjustment component; blending together the butanol stream with the octane improving component stream; and blending together the butanol stream with the vapor pressure adjustment component stream, wherein the butanol stream blended with the octane improving component stream and the vapor pressure adjustment component stream forms a product stream primarily including the composition.
