About CNS-1 catalyst for COS hydrolysis

CNS-1 catalyst for COS hydrolysis is prepared by partial oxidation of coal, tar etc. raw materials. COS, mainly acting as organic sulfur, always co-exists with sulfureted hydrogen, whose content depends on the sulfur content of raw materials and the processing conditions of partial oxidation. Being neutral or weak acid, COS is difficult to be removed by conventional desulfurizastion, resulting in a series of troubles on subsequent operating procedures or products qualities caused by reacted H2S and remained COS. Seeking for a efficient, simple & convenient catalyst and method to remove COS is a problem need to be solved urgently of the factory (especially methanol f/actory). CNS-1 catalyst for COS hydrolysis  is specially researched for the purpose of fine desulfurization of COS.
