METHOD FOR CATALYTIC REFINEMENT OF PETROLEUM LIGHT HYDROCARBONS, FOLLOWED BY LOW-TEMPERATURE CATALYST REACTIVATION Russian patent published in 2006 - IPC C10G11/05 C10G11/12 C10G11/14

Abstract RU 2276182 C2

FIELD: petroleum refinery, in particular method for catalytic refinement of petroleum light hydrocarbon cuts.

SUBSTANCE: petroleum light cuts are fed into catalyst cracking reaction; brought into contact with regenerated catalyst at temperature of 200-450°C, pressure of 0.1-0.5 MPa for 1-20 s followed by separation of reaction products. Stripped catalyst is regenerated for 10-50 min at temperature of 400-600°C and pressure of 0.1-0.6 MPa. Regenerated catalyst is recycled into reactor.

EFFECT: gasoline with decreased olefin content; diesel fuel with increased cetane number and partially decreased sulfur and nitrogen content.
