摘要:
Isomerizable light paraffinic hydrocarbon feeds are isomerized in an improved process using a particular super-chlorided reforming catalyst under isomerizing conditions. A chloride source in the feed stabilizes the catalyst. This process provides for a material octane improvement of the feed without excessive loss thereof to normally gaseous hydrocarbons.
摘要:
Mineral oils containing minor or residual amounts of sulfur-containing impurities are upgraded by contact thereof with a cobalt oxide-supported sorbent under sulfur-sorbing conditions. The sorbent is regenerated by a set of sequential treatment steps.
摘要:
A petroleum oil containing, in parts by weight, at least 10 parts of vanadium and/or nickel per million parts of the oil is upgraded by contacting the oil in the liquid phase with an aqueous solution of at least one extraction agent of the group ferric salts soluble in acidified water and stannic chloride. The aqueous solution must have a pH at least sufficiently acidic to inhibit precipitation of the agent as hydroxide or basic salt.
