Principle of hydrogen in suppressing carbon deposition
Thread Content
I would like to ask everyone how hydrogen inhibits the carbon deposition reaction and what is the mechanism behind it. Thank you
The hydrogen-to-oil ratio is very important as it helps to prevent carbon deposition; generally, a ratio of 800:1 to 1000:1 is suitable for hydrogenation reactions. During the vulcanization process, this ratio can be increased slightly, as the vulcanization of hydrogen sulfide and the reduction of hydrogen are competitive reactions. If there isn’t enough hydrogen sulfide, the catalyst will be reduced and thus unable to undergo vulcanization, which ultimately affects the catalyst’s activity.
