Abstract
A hydrocarbon feed containing an olefinic component and sulfur-containing impurities is upgraded in a sulfur removal process without hydrogenating the olefins by contacting a mixture of the feed and hydrogen gas with a catalyst comprising copper under conditions, including a temperature in the range of about 120.degree. C to 400.degree. C.
Claims10
A process for reducing the combined-sulfur content of a normally liquid hydrocarbon feedstock boiling below about 300.degree. C. and containing an olefinic hydrocarbon component, comprising contacting a mixture of said feedstock and hydrogen gas with a catalyst comprising copper metal, said contacting being effected without materially hydrogenating said olefinic component and under conditions including:
- a. a hydrogen partial pressure in the range of from about 0.2 to about 20 atmospheres;
- b. a temperature in the range of from about 120.degree. C. to 400.degree. C.;
- and
- c. at a liquid hourly space velocity in the range of from about 0.1 to 15.
