In the hydrodesulfurization unit, the organic sulfur compounds are converted into hydrogen sulfide over a layer of cobalt-molybdenum oxide hydrodesulfurization catalyst after mixing natural gas stream with small amount of hydrogen.
R-S-H (g) + H2 (g) → R-H (g) + H2S (g)
Kharazmi Technology Development Co. offers a special grade of organic sulfur removal catalyst for refinery, hydrogen and petrochemical plants. HDS-Ex-CM-01 is a cobalt molybdenum oxide on a high purity gamma alumina support with high surface area and high activity.
The pore size distribution, surface area, molybdenum surface area, pellet crush strength and bulk density is optimized during the manufacturing process. This catalyst is produced in the extrudate shape with ribbed sides to give a high geometric surface area.
