Too much vulcanizing agent was used, causing the reaction temperature to rise rapidly – can cold hydrogen be used?

When pre-sulfurizing a catalyst, it is important to follow the principle of raising the temperature without adding sulfur, and adding sulfur without raising the temperature! If the temperature gets too high, cold hydrogen can be used to control it! Also, what type of device do you use as a catalyst that requires presulfurization?
I don’t understand – you’re at 800 degrees; is sulfurization a catalyst? Are you using dry vulcanization? Where does the temperature rise come from?
I want to delete the post; it’s 80°, I need to add an extra 0. This mistake will not be made again. I’d like to tell you all here. I'm sorry
The original poster, please describe it in detail so that everyone can offer their suggestions
It can be operated; the hydrogen sulfide and cold hydrogen valves need to be properly tested
