Abstract:
     Said invention uses ferrous hydroxide (iron hydroxide) in a buffer solution consisting of acetic acid, sodium (potassium) acetate and ammonia to eliminate H2S, O2 and CO2 from gas under the catalytic action of hydroquinone or salicylic acid. Said method overcomes the problems of high limiting value for sulfur removal, heavy corrsion, serious ammonia loss and environmental pollution of previous several desulfurization methods and dilute ammonia water catalytic oxidation method, and solves the disadvantages of poor buffer capacity of desulfurizing liquor of semi-water gas desulfurizing deoxygenation method. It is characterized by good desulfurizing deoxygenation effect, simple technological process, low cost, free from environmental pollution, and is applicable to desulfurization of waste gas.
