Title:
DESULFURIZING AGENT AND METHOD FOR DESULFURIZATION OF HYDROCARBON
Document Type and Number:
WIPO Patent Application WO/2000/048733
Kind Code:
A1
Abstract:
A method for producing a desulfurizing agent characterized in that it comprises admixing a mixed aqueous solution containing a copper compound and a zinc compound with an alkaline aqueous solution to thereby form a precipitate, calcining the resultant precipitate, providing a molding of a copper oxide-zinc oxide mixture from the resultant calcined product, incorporating iron or nickel into the molding through impregnation, again calcining the product thus obtained and reducing the resultant calcined oxide with hydrogen, a method for desulfurizing a hydrocarbon stock using the desulfurizing agent.
