1.Features and Scope of Application
T306 Zinc Oxide Desulfurization Sorbent, 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 sulfide
H2S+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 + 2H2S
C2H5SH + H2 = C2H6 + H2S
Then hydrogen sulfide is absorbed by zinc oxide
H2S+ZnO=ZnS+H2O
b. Zinc oxide reacts directly with organic sulfur compounds
COS + ZnO = ZnS + CO2
T306 is an ideal desulfurization sorbent for deep purification cases, especially those at higher temperature (350--400℃).
