PROCESS FOR REGENERATING A CATALYST |
摘要 |
A process for regenerating a fixed bed of Fischer-Tropsch catalyst particles, of which at least 40 wt % of the catalyst particles have a size of at least 1 mm, in situ in a Fischer-Tropsch reactor tube. The process comprises the steps of: (i) optionally oxidising the catalyst at a temperature between 200 and 400° C.; (ii) oxidising the catalyst at a temperature above 580° C. and below 670° C.; and (iii) reducing the catalyst with hydrogen or a hydrogen comprising gas. This process may be preceded by a step in which Fischer-Tropsch product is removed from the catalyst.
