摘要： A process for regenerating one or more deactivated cobalt comprising Fischer-Tropsch catalyst particle(s), comprising the steps of: (i) oxidising the catalyst particle(s) at a temperature between 20 and 400° C.; (ii) treating the catalyst particle(s) for more than 5 minutes, (iii) drying the catalyst particle(s); and (iv) optionally reducing the catalyst particle(s) 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 particle(s). The treatment is performed using carbon dioxide and a liquid comprising ammonia.

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 oxidizing the catalyst at a temperature between 200 and 400° C.; (ii) oxidizing 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.
