Under laboratory conditions , simulate a fixed bed reactor , and explore Superfine iron oxide and manganese oxide as the main active component , carbonyl sulfide, desulfurization effect factors as well as the appropriate regeneration conditions , and the desulfurizing agent to the desulfurization agent life . Carbonyl sulfide and hydrogen sulfide concentration in the gas phase mass spectrometer outlet gas line detection and analysis of the desulfurizer the sulfur tolerance Coulomb sulfur measurement instrument and analysis using intelligent particle strength testing machine mechanical strength of the desulfurizer . The experimental results show that : the desulfurization agent having excellent desulfurization performance , high sulfur tolerance and mechanical strength . Experiments investigated the kind and amount of additives , the extrusion method , the influence of the preparation conditions of the water addition , the drying temperature and time , calcination temperature and time, etc. , and operating conditions such as reaction temperature, space velocity , etc. on the desulfurization effect . The results show that : dried at 120 ℃ 4h, 500 ° C and calcined 10H , the reaction temperature was 400 ° C , the space velocity was 1000h-1 under the conditions , the desulfurizing agent has a good desulfurization performance , the outlet concentration of carbonyl sulfide by 10000 × 10-6 reduced to 0.1 × 10-6 , while the outlet concentration of hydrogen sulfide as low as 2.8 × 10-6; the desulfurizer mechanical strength 92.6N/cm, sulfur capacity of 31.58gS 100g- 1 . The effects of the regeneration reaction temperature regeneration regeneration conditions such as the concentration of oxygen in the atmosphere and the water vapor concentration on the desulfurization effect of the desulfurization agent in the regenerated . The results show that : the optimum conditions for regeneration of the desulfurizing agent is: a regeneration temperature of 700 ° C , 45% H2O , the water vapor concentration in the regeneration atmosphere , and an oxygen concentration of 0.5% O2 , and after regeneration of the desulfurization agent having excellent desulfurization effect .
