Embodiment 1
[0014] Dissolve 0.1mol of chromium nitrate and 0.3mol of cerium nitrate in 300mL of ethanol, add 40g of activated carbon particles to it, and its specific surface area is 800m 2 / g, the system was heated and stirred at 90°C and evaporated to dryness, and then burned in a nitrogen atmosphere at 400°C for 3 hours to obtain a catalyst capable of simultaneous desulfurization and denitrification at low temperature.
Embodiment 2
[0016] Dissolve 0.1mol of chromium sulfate and 0.5mol of cerium chloride in 500mL of water, add 600g of active coke particles to it, and its specific surface area is 200m 2 / g, the system was evaporated to dryness with heating and stirring at 110°C, and burned in an argon atmosphere at 600°C for 5 hours to obtain a catalyst capable of simultaneous desulfurization and denitrification at low temperature.
Embodiment 3
[0018] Dissolve 0.1mol chromium chloride and 0.1mol cerium sulfate in 200mL water, add 40g active coke particles to it, its specific surface area is 600m 2 / g, the system was evaporated to dryness with heating and stirring at 105°C, and burned in a helium atmosphere at 500°C for 4 hours to obtain a catalyst capable of simultaneous desulfurization and denitrification at low temperature.
