Desulfurizer is the agent to remove free sulfur or sulfur compounds from fuel, raw materials or other materials. In the control or treatment of pollutants, it in mainly refers to agents used to remove sulfur oxides (including SO2 and SO3) in the exhaust gas. Various basic compounds can be used as a desulfurizer. Desulfurizer used in removal of sulfur dioxide in flue gas the most inexpensive lime, limestone and calcareous alkaline solution. Desulfurizer can absorb most of the sulfur dioxide in flue gas before discharge. It can be used for lime spray absorption or incorporated directly into pulverized coal solid lime powder and injected into the burner to fix the sulfide into fuel residue. Chemical plants, smelters and others often use sodium carbonate, an alkaline solution of aluminum sulfate, both of which can be recycled after desorption, as desulfurizer in the treatment of exhaust gas containing sulfur dioxide.

Desulfurizing principle of iron oxide desulfurizer is sulfur-containing compounds in waste gas adsorption into the holes of desulfurizer, thereby purifying gas. When desulfurizer after reaching saturation, namely its desulfurization ability, no longer need to be recycled, such as by steam stripping regeneration.
Ferric oxide desulfurizer, however, after using for a long time, its activity will continue to decline, as the holes is obstructed by some impurity content, can be recycled waste desulfurizer of the active ingredient. Iron oxide desulfurizer mainly iron oxide as the main active components, add a variety of catalyst and carrier to make.
▪ It is widely used in fertilizer,chemical,petrochemical,coal chemical etc. Industry raw material
▪ the removal of hydrogen sulfide in process gas,the dry removal of H2S in the sulfur-bearing gas such as natural gas,watergas,semi-water gas,carbon gas,shift gas,coke oven gas,liquefide
gas,methane,CO2and city gas.
▪ It also has good effect of organic sulfur's desulfurization.
Working Principle:
Desulfuration Reaction: Fe2O3.H2O+3H2S=Fe2S3.H2O+3H2O
Renewal Reaction: 2Fe2S3.H2O+3O2=2Fe2O3.H2O+6S (strong exothermic reaction)
Note: The desulfuration renewal can be cyclic regeneration when there is O2 or O2/H2S≥2.5 in the air, and the reaction formula combines into 2H2S+O2=H2O+2S with the iron oxide as the catalyst
