Sulfur recovery issues
Thread Content
When vulcanizing, are there any requirements on the temperature of H2S? Can vulcanization be performed at room temperature?
Of course, pre-vulcanization has temperature requirements. Pre-vulcanization starts at around 200 degrees and the heating rate is controlled. At the same time, the hydrogen sulfide content is measured,
If there are temperature requirements, we use cobalt catalyst, which must be heated first and then sulfurized.
How to vulcanize if the reactor has no temperature? No response
During pre-sulfurization, there are no requirements for the temperature of H2S, but the reactor cannot be pre-sulfurized at room temperature and must be raised to above 200 degrees!
