Iron oxide desulfurization agent because of its high sulfur content, low price, can be recycled at room temperature and so on, and is welcomed by users. But there are also poor strength, meet, desulfurization gouache precision (1ppm) and other shortcomings, affecting its industrial application. In view of the above situation, our company technical personnel after several years of painstaking research, developed a series of hyf new type of iron oxide desulfurization agent, which is characterized by: 1, high desulfurization accuracy: imported h2si1000ppm, the export of 0.05ppm h2s, than the average fe2o3 of the desulfurization accuracy (1ppm) 20 times higher; 2, fast response: the use of 1000-20000h-1 fe2o3 to be higher than ordinary airspeed 3 - 6 times. 3, work (through) sulfur capacity: under the conditions of 1 and 2, a one-time fine removal of h2s sulfur content of o2 is 20% - 3, 15 - 6 times the average fe2o3 desulfurization agent. 4, good strength, good water resistance. Boiled 2h or soak for 30 days without powder, strength unchanged. 5, suitable for a wide range of temperature, 90 - 5 6, can be used in the absence of o2 or high co2 conditions. H2s sulfur content 12 - 15%. The application of desulfurization of natural gas, water gas and semi water gas, air gas, coke oven gas, gas, and co2 transform anger, food co2, steel raw material gas, methane gas, petrochemical and other gases finishing off h2s, and can also be matched with 504 h2s+co2 hydrolysis catalyst reaches more than 0.06ppm, compensate for the lack of active carbon desulfurization the agent, so that the iron oxide desulfurizer new technology has been widely used.
