By studying the sulfurizing regents addition and the operating condition during the sulfurization process, it was determined that the sulfurization rate of the catalyst active components could reach the standard with the method of Energy Dispersive Spectrometer. The results of catalyst performance evaluation showed that catalyst could meet the performance requirement, which definited the feasibilities of sulfurization technology in Claus tail gas hydrogenation catalytic field.
