SDT-DS106 Room temperature desulfurizer for propylene refining
1. Uses and characteristics
SDT-DS106 high-efficiency desulfurizer for propylene refining is a strip desulfurizer developed according to the characteristics of propylene refining raw materials, which is based on iron salt as the basic raw material, converted into special activated iron oxide through chemical synthesis, and processed by adding composite additives and binders. The product has the characteristics of high active substance content, special structure, large sulfur capacity, low use resistance, high purification degree of hydrogen sulfide, good oil resistance, etc., and is used for the removal of hydrogen sulfide and small molecule mercaptans in propylene refining, and can be used in conjunction with carbonyl sulfur hydrolysis catalyst to remove hydrogen sulfide and carbonyl sulfur in propylene raw materials to less than 0.1ppm.
Principle of desulfurization:
FeO(OH)＋2H2S 
FeSSH +2H2O
