摘要： A cyclic process for obtaining very pure alumina by the hydrochloric acid attack of a silico-aluminous material, the said process comprising, in a first stage, the precipitation of at most 75% of the alumina present in the liquor originating from the attack in the form of hexahydrated aluminum chloride which is subsequently decomposed by heating, then, in a second stage, the treatment of the liquor leaving the first stage with HCl gas in order to precipitate dissolved Al.sub.2 O.sub.3 in the form of hexahydrated aluminum chloride which is recycled into the liquor leaving the attack, while the hydrochloric liquor leaving the second stage and impoverished in Al.sub.2 O.sub.3 but rich in impurities, is treated with a recycled sulphuric liquor in order to precipitate impurities as their corresponding sulphates.

摘要： A process is disclosed for recovering metallic constituents of spent or waste catalysts containing metallic compounds fixed on an aluminous support. The process is particularly applicable for the recovery of metals such as Al, Mo, V, Ni and Co, contained in spent catalyst. The process comprises transforming the metals to be recovered into volatile chlorides by carbochlorination and then separating the chlorides obtained by dry means and fixing them successively in a selective manner. The separation of AlCl.sub.3 is accomplished by passage through granules of anhydrous NaCl, and the separation of MoCl.sub.5 by passage through granules of crystallized KCl. The process is particularly suitable for the treatment of waste catalyst from the catalytic hydrocracking or hydrodesulfurization of oils.
