Sulfur recovery

Does the catalyst need to be pre-sulfurized in sulfur recovery?
The reactor is not required; the hydrogenation reactor is needed
The thermal reaction section for sulfur recovery is an endothermic reaction; a decrease in temperature and pressure facilitates the progress of the reaction, thereby increasing the conversion rate. Sulfur recovery refers to the chemical process of converting sulfides in toxic sulfur-containing gases such as hydrogen sulfide into elemental sulfur, thereby turning waste into a valuable resource and protecting the environment. The main principle of the hydrogenation reduction sulfur recovery process is to use hydrogen to treat the exhaust gases from the sulfur recovery unit.
There are pre-sulfided catalysts available on the market.
