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 has a size of at least 1mm, in situin 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.
