Abstract The sulfurizing process suitable for catalyst, especially that for residual oil hydrogenating treatment includes: the low temperature dry sulfurization with H2S or other sulfurizing agent and the high temperature wet sulfurization with sulfurizing oil to catalyst bed layer. Compared with traditional process, the process of the present invention has high catalyst sulfurizing efficiency, high initial activity of catalyst, short sulfurizing period, less sulfurizing oil consumption and low sulfurizing cost.
