Appl. No.:

12/650816

Inventors:

Hye-Kyung Timken - Albany CA, US
Christine Phillips - Pleasant Hill CA, US
Robert F. Cleverdon - Walnut Creek CA, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

C07C 7/04
C10G 7/00
C10L 1/06

US Classification:

585800, 208 16, 208 17, 2082621, 208347

Abstract:

A process for making products with low hydrogen halide, comprising: a) stripping or distilling an effluent from a reactor into a first fraction having an amount of hydrogen halide, and a second fraction having a reduced amount of hydrogen halide; wherein the reactor comprises: an ionic liquid catalyst having a metal halide, and a hydrogen halide or an organic halide; and b) recovering one or more product streams, from the second fraction, having less than 25 wppm hydrogen halide. In one embodiment the ionic liquid catalyst has metal halide; and the recovering recovers propane, n-butane, and alkylate gasoline having less than 25 wppm hydrogen halide. In another embodiment the recovering uses a distillation column having poor corrosion resistance to hydrogen halide; and the distillation column does not exhibit corrosion. There is also provided an alkylate gasoline having less than 5 wppm hydrogen halide, a high RON, and low RVP.

Abstract:

A process for hydrocarbon conversion, comprising: a) stripping or distilling a hydrocarbon effluent from a reactor comprising an ionic liquid catalyst having: a metal halide, and a hydrogen halide or an organic halide into a first and second fraction, and b) recycling at least a portion of the first fraction comprising at least 5 wt % and less than 95 wt % of the hydrogen halide to the reactor. A process comprising: a) stripping or distilling a hydrocarbon effluent from a reactor comprising an ionic liquid catalyst into a first fraction having at least 5 wt % of hydrogen halide and a second fraction having less than 25 wppm hydrogen halide; and b) recycling at least a portion of the first fraction to the reactor to improve the selectivity of products. A process comprising recycling of the catalyst, the first fraction, and a portion of the second fraction that is an isoparaffin to the reactor.
