    A kind of furol slag activated carbon catalyst is obtd. by using CO2, ammonia, Ar or N2 to proceed the modifying treatment in the course of preparation. Said catalyst is used for eliminating and recovering SO2 in the flue gas, the main process including dusting, adsorption, oxidation and mordanting and water washing for regeneration. By using said method the atmospheric pollution of SO2 in the tail gas exhausted from sulfuric acid factory, smeltery, chemical plant and power plant can be effectively eliminated, at the same time, sulfuric acid with concentration about 30% can be recovered. Said method is specially suitable for decontaminating treatment for such flue gas as containing fair amount of dust and relative low SO2.
