Gasoline hydrogenation
Thread Content
In the gasoline hydrogenation process, the pre-hydrogenation protection reactor experiences a temperature rise of 5–10 degrees, while the pre-hydrogenation reactor itself shows almost no temperature rise. Why is this? Our pre-hydrogenation protection reactor is equipped with the same catalyst as the pre-hydrogenation reactor, but in smaller quantities. What are the respective functions of the pre-hydrogenation protection reactor and the pre-hydrogenation reactor? What are the main reactions that occur? I hope the seniors can give me some guidance! ! ! :P
Protecting the reactor involves mainly loading a protective agent to reduce the poisoning of the main agent caused by the failure of this protective agent.
Our protection reactor is filled with ceramic balls and porous balls, as well as GDS-10 catalyst; however, this catalyst is also alumina, and it is primarily used to protect the pre-hydrogenation reactor’s catalyst. The function of the pre-hydrogenation reactor is to react dienes with thiol compounds to form sulfides that are present in heavy gasoline, thereby ensuring a controlled sulfur content in light gasoline It also serves to remove dienes and thiols
Diene and thiol react to form thioethers. How does this reaction work? In that case, will the loss in octane rating be significant? Is this reaction the main one for the conversion of sulfur from light gasoline to heavy gasoline? If not, what other reactions are there?
