WebHydrodesulfurization is a high-pressure (150 to 250 psig) and high-temperature (200 to 425°C) process that uses hydrogen gas to reduce the sulfur in petroleum fractions (particularly diesel) to hydrogen sulfide, which is then readily separated from the fuel. Hydrodesulfurization units are expensive to build and operate. WebFrom the nondetection of HDS in its 211-212 transition, we estimate the abundance ratio [HDS]/[H2S] ≤ 0.02 in the hot core.

The resulting exhaust is a sour gas mainly containing H 2 S which is highly toxic and life-threatening.

WebThe HDS catalyst also acts as a trapping agent for many of the less usual poisons, such as metals (if present). Where necessary, a second-stage absorbent follows the HDS to remove hydrogen chloride by chemical reaction. The third stage is removal of hydrogen sulfide using absorbents based on zinc oxide, which reacts to form zinc sulfide. WebHydrogen sulfide occurs naturally and is also produced by human activities.
