Abstract: This invention pertains to a new process for removing metals, especially contaminant metals, from spent catalysts. Also, this invention pertains to a catalyst composite with metals removed by the new process, and to several uses for the catalyst, including as a rejuvenated hydrotreating catalyst. The new process comprises (i) contacting the spent catalyst with a complexing agent with four or more coordinating groups, including at least two carboxylic acid type groups and at least one amino type group, and (ii) separating from the spent catalyst a mixture containing the complexing agent and the removed metals. By this process contaminant metals, like vanadium, are more selectively removed from the spent catalyst than are catalytic metals, like cobalt and molybdenum.
