Process for regenerating a catalyst

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 with a solvent, which solvent comprises an amine, (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).
