1.Features and Scope of ApplicationT306 Zinc Oxide Desulfurization Adsorbent, developed by the Northwest Research Institute of Chemical Industry, is applicable to desulfurization of residue cracking gases or syngas and purification of feed gases for organic synthesis processes. It is suitable for both higher (350--408) and lower(150--210) temperature use. It can convert some simpler organic sulfur while absorbing inorganic sulfur in gas stream.Main reaction of the desulfurization process is as follows:(1) Reaction of zinc oxide with hydrogen sulfideH2S+ZnO=ZnS+H2O(2) Reaction of zinc oxide with some simpler sulfur compounds in two possible ways:a. Organic sulfur compounds, catalyzed by zinc oxide, react with hydrogen to form hydrogen sulfide:CS2 + 4H2 = CH4 + 2H2SC2H5SH + H2 = C2H6 + H2SThen hydrogen sulfide is absorbed by zinc oxideH2S+ZnO=ZnS+H2Ob. Zinc oxide reacts directly with organic sulfur compoundsCOS + ZnO = ZnS + CO2T306 is an ideal desulfurization adsorbent for deep purification cases, especially those at higher temperature (350--400).2.Physical Properties Related Product Searches:T306 Zinc Oxide Desulfurization Adsorbent,High Quality,T306 Zinc Oxide Desulfurization Adsorbent, Zinc Oxide Zinc Oxide Desulfurization Adsorbent,T-306
