摘要：There is provided a process for hydrocarbon synthesis wherein a supportedmetal catalyst for hydrogenating carbon monoxide to form a mixture of hydrocarbons isregenerated by decreasing its hydrocarbon content, impregnating under a non-oxidativeatmosphere with a solution of at least one member selected from the group consistingof ammonium salts, alkyl ammonium salts and weak organic acids, optionally includingammonia, oxidizing with a gaseous oxidant in the presence of the impregnating solution,activating the catalyst by reduction with hydrogen at elevated temperatures and reusingthe catalyst. The treatment may be carried out in a single reactor, or by carrying out upto all steps after catalyst has been withdrawn therefrom and returned to at least onereactor. Up to all steps subsequent to decreasing the hydrocarbon content may beeffected in a subsequent reactor, or in specialized apparatus.
