摘要: The present invention discloses aqueous methods for enhancing the acid sites of fluid catalytic cracking (FCC) catalysts. The methods comprise the steps of contacting an FCC catalyst, either spent or fresh, with an aqueous solution comprising water, an inorganic acid substantially free of chloride and aluminum. The acid is preferably sulfurous or sulfuric acid. The aluminum is provided by an aluminum source selected from the group consisting of the alumina trihydrates and aluminum oxide. Chloride contamination of the aluminum source should be minimal, preferably less than about 1000 ppm chloride, more preferably less than about 200 ppm chloride. The pH of the aqueous solution is adjusted to about 3-12 by the addition of a sufficient quantity of ammonium hydroxide. The FCC catalyst is added to this solution, preferably with stirring, in a weight ratio of about 1 part catalyst to about 1-10 parts water to prepare an aqueous slurry. Upon stabilization of the pH of the aqueous slurry, enhancement of the acid sites of the catalyst is achieved and the catalyst may be separated from the slurry and, if desired, washed. This simple, aqueous process reduces the level of many metal poisons on the FCC catalyst and produces a catalyst having an enhanced number of acid reaction sites.
