1. Performance Characteristics and Applications:
1. High desulfurization accuracy: When the inlet H2S is 10000 ppm, the outlet H2S≤ 0.03ppm， The desulfurization accuracy (<1ppm) is 30 times higher than that of ordinary Fe2O3;
2. Fast reaction speed: Using an air velocity of 1000-2000h-1, it is 3-6 times higher than ordinary Fe2O3;
3. Large working (penetration) sulfur capacity: Under conditions 1 and 2, the one-time precision desulfurization of H2S sulfur capacity with O2is 15-20%, which is 3-6 times that of ordinary Fe2O3desulfurizers. The industrial side flow test of 8 domestic iron oxide desulfurizers by Beijing Chemical Experimental Factory showed that T703 type precision desulfurizer has the highest working sulfur capacity and is far ahead, 3-5 times that of other iron oxides.
4. Good strength and water resistance. Boil for 2 hours or soak for 30 days without powdering, and the strength remains unchanged; After 100 impact tests of sudden charging and unloading under a pressure of 12Mpa, there was no change in strength.
5. Wide applicable temperature range, 5-90 ℃.
This precision desulfurization is suitable for the precision desulfurization of various gases such as natural gas, water gas, semi water gas, air gas, coke oven gas, shift gas, CO2regenerated gas, food CO2, synthetic raw material gas, biogas, exhaust gas, etc. It can also be used in conjunction with T504 hydrolysis catalyst for precision desulfurization of organic and inorganic sulfur.
