  • Publication number: 20100081567
    Abstract: A process for the sulfidation of a sour gas shift catalyst, wherein the temperature of the sulfidation feed stream is coordinated with the sulfur/hydrogen molar ratio in that feed stream to obtain enhanced performance of the sour gas shift catalyst. In the sulfidation process to produce a sour gas shift catalyst, the lower the sulfur to hydrogen molar ratio of the sulfidation feed stream, the lower the required temperature of the sulfidation feed stream. The sulfidation reaction can be further enhanced by increasing the pressure on the sulfidation feed stream.
