摘要： A method is provided for regenerating a molecular sieve-free resid hydroprocessing catalyst for use with an ebullated bed reaction process comprising at least one hydrogenation metal and at least one Group IIA metal deposited on an inorganic oxide support wherein the catalyst contains a pore volume of pores having a diameter greater than 1200 Angstroms of at least 0.05 cc/gm. The method comprises the steps of contacting the molecular sieve-free resid hydroprocessing catalyst with a contaminant metal-containing hydrocarbon feedstream in a first contacting step at conditions sufficient to deposit contaminant metals and coke onto the catalyst; and contacting the coke-deactivated, contaminant metal-containing, molecular sieve-free catalyst with an oxygen-containing gas in a second contacting step at oxidation conditions sufficient to remove a substantial amount of the coke from the coke-deactivated, contaminant metal-containing, molecular sieve-free catalyst. The loss on attrition of the regenerated molecular sieve-free resid hydroprocessing catalyst after the second contacting step is less than 10 weight percent fines per day calculated based on a regeneration temperature of about 900.degree. F.
