摘要

With that low the intermediate fraction supply raw materials which possess, the high density of the sulfur in order to obtain the sulfur intermediate fraction product, for example, production method of the high active catalyst composition which is suited for the use in desulfurization of the Diesel fuel and the like. As for this method, converting aforementioned aluminum hydroxide to the gamma - alumina by heating processes aluminum hydroxide under the temperature condition which is controlled, the aforementioned aluminum hydroxide everything is converted to the transition alumina essentially the description above which is the gamma - alumina process, and the description above which obtain the aluminum hydroxide which is converted the temperature condition which is controlled, by from 850 F (454 ) controlling inside the burning temperature range of 950 F (510 ), by controlling the fraction of the aluminum hydroxide which is converted, but under the amount of substance of the aluminum hydroxide which is converted, gammaThe process which is converted to the transition alumina other than the - alumina is included. As for the catalyst component, the description above being introduced in the aluminum hydroxide which is converted, profit, this, is heated is processed the intermediate field in order to obtain the aforementioned high active catalyst composition.
