Title:
CATALYST FOR HYDRODESULFURIZATION OF HYDROCARBON
Document Type and Number:
WIPO Patent Application WO/2004/018097
Kind Code:
A1
Abstract:
An impregnant solution for hydrocarbon hydrodesulfurization catalysts which comprises at least one Group 6 metal of the Periodic Table, at least one Group 8 metal of the Periodic Table, and/or a phosphorus compound, and a sugar derivative; and a catalyst for the hydrodesulfurization of hydrocarbons which is obtained by impregnating a support with the impregnant solution and then drying the impregnation. The impregnant solution is stable over a wide pH range. The hydrodesulfurization catalyst has excellent hydrodesulfurization performance, especially in the desulfurization of compounds difficult to desulfurize. It is inhibited from functioning to hydrogenate unsaturated hydrocarbons and does not cause the isomerization/decomposition attributable to the function of solid acids. The catalyst is hence extremely useful as a catalyst for the superdeep hydrodesulfurization of gas-oil fractions, etc.
