Presulfuration of hydrogenation catalyst is an essential technology, which can enhance the catalyst activeness and optimize operation of hydrogenation catalysis and obtain ideal economic efficiency. In order to obtain the ideal presulfiding effect,the conditions of various stages should be controled strictly. It introduced the principal of presulfuration of hydrogenation catalyst and discussed the factors that affected the effect of presulfuration in presulfiding process. During the presulfiding operation, the temperature is one of the most sensitive factors .
