| titleOfInvention | PROCESS TO REGENERATE A COBALT FISCHER-TROPSCH SYNTHESIS CATALYST |
| abstract | A process for regenerating a worn-out, cobalt-based Fischer-tropsch synthesis catalyst is provided, which contains particulate wax. The process includes subjecting the worn catalyst, which contains waxes, consecutively to a wax extraction treatment, an oxidation treatment and a reduction treatment. During the wax extraction treatment, the already worn catalyst, which contains waxes, the waxes are extracted at least partially, with production of catalyst particles devoid of waxes. During the oxidation treatment, an oxygen-containing gas is passed through a bed of the catalyst particles devoid of waxes at an operating temperature TsC where 150 <T <450, and the operating temperature is controlled by heat removal of the catalyst particle bed using a cooling device, to obtain oxidized catalyst particles. During the reduction treatment, the oxidized catalyst particles are reduced, thereby regenerating the catalyst. |
