Abstract:containing volatile organic compound, was introduced in this paper.The active centers andcorresponding reaction/deactivation mechanisms were analyzed. Based on a series of characterizationtechniques such as XPS and H2-TPR,reactive oxygen species,redox sites and acid-basic sites wereconsidered as the main active centers for catalytic decomposition of methyl mercaptan. To solve the cat⁃alyst poisoning problem,it is suggested to convert the catalyst sulfur poisoning into coke poisoning,andthen solve the coke poisoning by adding different metal additives and replacement carriers to regulatethe active centers.
