Abstract
Processes for producing mixed alcohols from mixed olefins and the catalyst systems for making such alcohols are provided. Additionally, processes for producing fuel compositions having mixed alcohols prepared from mixed olefins are also provided as embodiments of the present invention. The catalyst systems include a dual phase catalyst system that includes a water soluble acid catalyst and a solid acid catalyst.

A process for producing mixed alcohols from mixed olefins using a butene hydration system, the process comprising the steps of:
- introducing a mixed olefin stream comprising mixed olefins into the butene hydration system;
- contacting the-mixed olefin stream with a dual phase catalyst system within a reactor to convert the mixed olefins into mixed alcohols;
- and
- producing a mixed alcohol stream comprising the mixed alcohols from the butene hydration system;
- where the dual phase catalyst system comprises a water soluble acid catalyst and a solid acid catalyst,
- where the water soluble acid catalyst is soluble in water and the solid acid catalyst is insoluble in water,
- where the butene hydration system includes the reactor that is operable to contain the dual phase catalyst system,
- where the dual phase catalyst system is capable of hydrating the mixed olefin stream without requiring separation of the mixed olefins prior to contacting the mixed olefin stream with the dual phase catalyst system,
- where the mixed olefins comprise at least two types of butenes,
- where the mixed alcohols comprise at least two types of butanols, and
- where the conversion rate of converting introduced mixed olefins into mixed alcohols in the reactor is at a rate greater than about 10% and the ratio of 2-butanol to t-butanol in the mixed alcohols is greater than about 2.0.
A process for producing a fuel composition from mixed olefins using a butene hydration system, the process comprising the steps of:
- introducing a mixed olefin stream comprising the mixed olefins into the butene hydration system;
- contacting the mixed olefin stream with a dual phase catalyst system within a reactor to convert the mixed olefins into mixed alcohols;
- producing a mixed alcohol stream comprising the mixed alcohols from the butene hydration system;
- and
- combining the mixed alcohol stream with a fuel component to produce the fuel composition;
- where the dual phase catalyst system comprises a water soluble acid catalyst and a solid acid catalyst,
- where the water soluble acid catalyst is soluble in water and the solid acid catalyst is insoluble in water,
- where the butene hydration system includes the reactor that is operable to contain the dual phase catalyst system,
- where the mixed olefins comprise at least two types of butenes,
- where the mixed alcohols comprise at least two types of butanols,
- where the conversion rate of converting introduced mixed olefins into mixed alcohols in the reactor is at a rate greater than about 10% and the ratio of 2-butanol to t-butanol in the mixed alcohols is greater than about 2.0, and
- where the fuel component is gasoline, diesel, jet fuel, aviation gasoline, heating oil, bunker oil, or a combinations thereof.
