PROCESS FOR REJUVENATING HYDROTREATING CATALYSTS |
摘要 |
The invention refers to a process for rejuvenating a hydrotreating catalyst comprising a group VIB hydrogenation metal and/or a group VIII hydrogenation metal, which comprises the steps of: (a) regenerating the catalyst by contacting said catalyst with an oxygen containing gas at a temperature from about 300° C. to 550° C. to obtain a regenerated carbon-reduced catalyst, (b) impregnating the regenerated carbon-reduced catalyst with a solution which consists of a mixture of water and citric acid, (c) aging the impregnated catalyst for at least 6 hours and (d) drying the aged catalyst. The invention also refers to the rejuvenated catalyst obtained and its use for hydrotreating hydrocarbon feedstocks. |
