Document Type and Number:
Japanese Patent JP4197073
Kind Code:
B2
Abstract:
A catalyst for deep desulfurization of a mineral oil corresponding to kerosene, comprising a nickel component of nickel and nickel oxide, zinc oxide, and aluminum oxide, wherein the content of the nickel component in terms of nickel oxide is from 5 to 25% by weight and the content of the zinc oxide is from 30 to 70% by weight each based on the total of the content of the nickel component in terms of nickel oxide, the content of the zinc oxide, and the content of the aluminum oxide, the nitrogen monoxide adsorption of the catalyst at 1 kg/cm<2> (9.80x10<-2> MPa) and 40 DEG C after hydrogen reduction at 360 DEG C is 4.0 ml/g or more in terms of standard-state, and the catalyst has a specific surface area of from 10 to 300 m<2>/g; the deep desulfurization catalyst, which is obtained by carrying out an activation treatment in the presence of hydrogen at a temperature of from 200 to 400 DEG C and a pressure of from 1 to 20 kg/cm<2> (9.80x10<-2> to 1.96 MPa); a process for producing the deep desulfurization catalyst, comprising mixing a basic substance with each of an aqueous solution of a water-soluble nickel metal salt and an aqueous solution of a water-soluble zinc metal salt or with a mixed aqueous solution thereof to thereby form precipitates separately or simultaneously, and mixing the precipitates with aluminum oxide or an aluminum oxide precursor, followed by molding and burning; and a method of deep desulfurization, comprising bringing a mineral oil corresponding to kerosene into contact with hydrogen in the presence of the above deep desulfurization catalyst at a temperature of from 200 to 400 DEG C, a pressure of from 1 to 20 kg/cm<2> (9.80x10<-2> to 1.96 MPa), and an LHSV (liquid hourly space velocity) of from 0.1 to 5.
