Process for regenerating a cobalt comprising Fischer-Tropsch 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, (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.
