abstract
The invention relates to a treatment method of hydrogenation catalyst before use. The specific process is to introduce organic solvents and sulfur-containing substances into the oxidation hydrogenation catalyst, and then heat it for pretreatment under certain conditions. The treatment method before the application of the hydrogenation catalyst of the invention loads sulfur-containing substances such as elemental sulfur on the hydrogenation catalyst, which has certain interaction and emits less heat. Compared with the prior art, the catalyst obtained by the method has the characteristics of high utilization rate of sulfur-containing substances, gentle temperature rise of the catalyst bed and high catalyst activity during activation. The method of the invention can be used in the treatment process before the application of various hydrogenation catalysts.
The inventor of this patent asked not to be named.
