    摘要： A process for regenerating one or more deactivated cobalt comprising Fischer-Tropsch catalyst particle(s), comprising the steps of: (i) oxidizing 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 producing a purified gas stream from a feed gas stream comprising contaminants, the process comprising the steps of: (a) removing contaminants from the feed gas stream to obtain the purified gas stream and a sour gas stream comprising H2S and RSH; (b) separating the sour gas stream comprising H2S and RSH into a gas stream enriched in H2S and a residual gas stream comprising RSH; (c) converting H2S in the gas stream enriched in H2S to elemental sulphur in a Claus unit, thereby obtaining a first off-gas stream comprising SO2; (d) converting SO2 in the first off-gas stream comprising SO2 to H2S in a Claus off-gas treating reactor to obtain a second off-gas stream comprising H2S; (e) converting RSH from the residual gas stream comprising RSH to H2S in an RSH conversion reactor to obtain a residual gas stream comprising H2S, wherein at least one of the operating conditions of the RSH conversion reactor is different from the corresponding operating condition of the Claus off-gas treating reactor.
