Catalyst sulfidation mechanism
Thread Content
The catalyst needs to be sulfided and passivated during use. In our company, dimethyl disulfide is used for this sulfidation process. What I would like to ask is: what is the sulfidation mechanism of dimethyl disulfide? How do chemical equations work? I checked, and the decomposition temperature of dimethyl disulfide is 390°C, while the vulcanization temperature does not reach such a high level; so isn’t its reaction carried out after decomposition? I appreciate your advice!
A vulcanizing agent reacts with hydrogen to produce hydrogen sulfide, which then reacts with metal oxides (catalysts) to form metal sulfides, thereby achieving vulcanization.
At what temperature can dimethyl disulfide and hydrogen in a vulcanizing machine react to produce hydrogen sulfide? About how many degrees?
