Abstract
Methods for producing alcohols and oligomers contemporaneously from a hydrocarbon feed containing mixed butenes using an acid based catalyst are provided. Additionally, methods for producing fuel compositions having alcohols and oligomers prepared from mixed olefins are also provided as embodiments of the present invention. In certain embodiments, the catalyst can include a dual phase catalyst system that includes a water soluble acid catalyst and a solid acid catalyst.
Claims7
A gasoline composition, the composition comprising:
- a fuel-grade gasoline;
- and
- an octane enhancing additive comprising mixed butanols and DIBs, wherein the octane enhancing additive is prepared by contacting a mixed butene stream with a dual phase catalyst system and water under conditions operable to oligomerize and hydrate the butenes to form the octane enhancing additive.
