hpf法脱硫（Desulfurization by HPF process） HPF HPFHPF HPF desulfurization Desulfurization desulfurization Desulfurization HPF desulfurization belongs to liquid phase catalytic oxidation desulfurization catalyst regeneration, HPF in the whole process are in desulfurization and Catalysis is the use of coke oven gas in ammonia absorber, HPF wet oxidation desulfurization catalyst, H2S in gas and other acidic component into the liquid phase and gas phase reaction by ammonia, converted to ammonium thiochloride acid ammonium salt, The oxidation of oxygen in the air into elemental sulfur. HPF process choose to use HPF (cobalt iron quinone complex) Combined type catalyst, the desulfurization efficiency of coke oven gas to reach about 99%. One one by one A, ,, HPF HPFHPF The basic reaction of HPF desulfurization The basic basic reaction for desulfurization desulfurization. The basic method of desulfurization reaction 1. desulfurization reaction NH3+H2O In the H2O NH3. NH3 - H2O +H2S In the NH4HS+H2O NH3 - H2O +HCN In the NH4CN+H2O NH3 H2O in +CO2 NH4HCO3 NH3 H2O in +NH4HCO3 (NH4) 2CO3+H2O NH3 H2O +NH4HS+ (x+1) in Sx (NH4) 2Sx+H2O 2NH4HS+ (NH4) 2CO3+2 (x-1) S In 2 (NH4) 2Sx+CO2+H2O NH rate Exergy in +NH4HCO3 NH4HOO-+H2O NH4HS+NH4HCO3+ (x-1) S In the (NH4) 2Sx+CO2+H2O NH4CN+ (NH4) 2Sx In the NH4CNS+ (NH4) 2S (x-1) (NH4) 2S (x-1+S) In the (NH4) 2Sx 2. regeneration reaction NH4HS+1/2O2, S: +NH4OH (NH4) 2Sx+1/2O2+H2O - Sx +2NH4OH NH4CNS: In the H2N-CS-NH2 in the H2N-CHS=NH H2N-CS-NH2+1/2O2 to H2N-CO-NH2=S: H2N-CO-NH2+2H2O In the (NH4) 2CO32 in the The 3. side reaction exergy NH4OH+CO2 2NH4HS+2O2, (NH4) 2S2O3+H2O 2 (NH4), 2S2O3+O2 (NH4) 2SO4+2S: HPF catalyst desulfurization by hydroquinone (H), PDS (Gu six bicyclic phthalocyanine ammonium sulfonate), ferrous sulfate (F) aqueous solution which is composed of small amounts of ADA, manganese sulfate and salicylic acid catalyst,. The catalytic mechanism of HPF desulfurization catalyst is still in further research, the components in desulfu
