Production of low-sulfur and olefin gasoline

Production of low-sulfure and low-olefin gasoline is carried out by entering raw oil into reactor with two reactive regions, contacting with thermal cracking catalyst under existence of aqueous vapor to have first and second reactions, separating reactant to obtain crude gasoline fraction, crude die...

Beschreibung
Zusammenfassung:	Production of low-sulfure and low-olefin gasoline is carried out by entering raw oil into reactor with two reactive regions, contacting with thermal cracking catalyst under existence of aqueous vapor to have first and second reactions, separating reactant to obtain crude gasoline fraction, crude diesel fraction and oil slurry, cutting the obtained crude gasoline fraction into light gasoline fraction and heavy gasoline fraction, removing sulfur alcohol by alkali washing for light gasoline fraction, contacting hydrogenation upgraded catalyst with total crude gasoline fraction or cut heavy gasoline fraction, selectively hydrogenation desulfurization reacting and separating to obtain the final product. It has less sulfur content, olefin content and RON.
