Embodiment 1
[0020] a SnCl 4 and V 2 o 5 as the active component, with activated carbon as the carrier, with Fe 2 o 3 and CeO 2 It is a desulfurization and denitrification catalyst as an auxiliary agent, and its raw material components are: tin chloride with a content of 0.1% of the mass of activated carbon, ammonium metavanadate with a content of 0.5% of the mass of activated carbon, iron nitrate with a content of 5.0% of the mass of activated carbon, The content is 2.0% cerium nitrate of activated carbon mass.
[0021] Its preparation process comprises the following steps:
[0022] Step 1. Weigh a certain amount of activated carbon, soak it in water for 2 hours, and wash it three to five times to remove surface impurities;
[0023] Step 2, dissolving tin chloride, ammonium metavanadate, ferric nitrate and cerium nitrate in water with 10 times the mass sum of the four at room temperature, adding oxalic acid with 3 times the mass of ammonium metavanadate as a cosolvent, stirring to f...
