SDT-DS116M Room temperature desulfurizer for refining
1. Uses and characteristics
SDT-DS116M MTBE is a strip desulfurizer developed according to the characteristics of MTBE refining raw materials, which uses iron salt as the basic raw material, is converted into activated iron oxide with hydroxyl structure through chemical synthesis, and processed by adding compound additives and binders. The product has the characteristics of high active substance content, special structure, large sulfur capacity, low resistance, high purification degree, good oil resistance, etc., and is used for the removal of hydrogen sulfide and mercaptan in MTBE refining, and can be used in conjunction with the catalyst to remove hydrogen sulfide and small molecule mercaptan in MTBE raw materials to less than 5.0ppm.
Principle of desulfurization:
FeO(OH)＋2H2S 
FeSSH +2H2O
