    摘要: A method for removing iron, calcium and various metals from coal fire generated catalysts. With the use of urea sulfate, urea hydrochloride and/or pH lowering compound in combination with a reducing compound, and chelating compound, the cleaning redeposition problem can be solved while minimizing the environmental impact from process chemicals. The urea sulfate or urea hydrochloride along with a reducing compound will solubilize, then converts, the metals into a form that will allow the chelate compound to safely remove the metals from the Catalyst. The solubilized metals are combined with the chelate to form an inert compound that will not redeposit back onto the substrate, thereby, allowing the materials to be removed from the system safely and efficiently with shorter process times.

    摘要: A process for slurry hydrocracking catalyst recovery is described. In one embodiment, the process includes separating effluent from a slurry hydrocracking zone into a first portion comprising solvent and clarified pitch and a second portion comprising pitch and catalyst. The second portion is contacted with an acid to leach the catalyst out of the pitch forming an aqueous solution and pitch residue. The aqueous solution is contacted with an anion to form an insoluble salt which is the catalyst.
