Abstract
Provided is a process for producing low volatility, high quality gasoline blending components from a number of isoparaffin feed streams, olefin feed streams, and ionic liquid catalyst streams. The process entails providing an isoparaffin feed stream comprising isoparaffins, an olefin feed stream comprising olefins, and a catalyst stream comprising ionic liquid catalyst, and subsequently splitting at least the reactive olefin feed stream for feeding into the reaction zone at different locations.
Claims16
A downflow process for the production of low volatility, high quality gasoline blending components comprising:
- (a) providing an isoparaffin feed stream comprising isoparaffins;
- (b) providing an olefin feed stream comprising olefins;
- (c) providing a catalyst stream comprising an ionic liquid catalyst;
- (d) splitting the isoparaffin feed stream, the catalyst stream, and the olefin feed stream into multiple isoparaffin feed streams, catalyst streams, and olefin feed streams;
- (e) feeding the multiple isoparaffin feed streams, catalyst streams, and olefin feed streams into a reactor at different feed sites along the length of the reactor in a downwardly direction to contact all the feed streams under alkylation conditions to provide a product comprising the low volatility, high quality gasoline blending components wherein the isoparaffin/olefin ratio increases along the length of the reactor;
- and
- (f) isolating the low volatility, high quality gasoline blending components from the product.

- (c) providing a catalyst stream comprising an ionic liquid catalyst;
- (d) splitting the isoparaffin feed stream and the olefin feed stream into multiple isoparaffin feed streams and olefin feed streams;
- (e) feeding the multiple isoparaffin feed streams and olefin feed streams into a vertical downflow reactor at different feed sites along the length of the reactor for each isoparaffin and olefin feed stream while also feeding the catalyst feed stream into the reactor to contact all the feed streams under alkylation conditions to provide a product comprising the low volatility, high quality gasoline blending components wherein the isoparaffin/olefin ratio increases along the length of the reactor;
- and
- (f) isolating the low volatility, high quality gasoline blending components from the product.
