    摘要: A process to treat/clean a gas, containing SO2, CO2 and O2 comprising the steps of: bringing the gas in contact with an activated carbon catalyst, converting SO2 to SO3/H2SO4 on the activated carbon catalyst, washing the SO3/H2SO4 from the activated carbon catalyst to obtain a sulfuric acid solution and a SO2 depleted gas; bringing the SO2 depleted gas in contact with an aqueous ammonia solution wherein CO2 is converted to obtain a SO2 and CO2 depleted gas containing ammonia; and bringing the SO2 and CO2 depleted gas containing ammonia in contact with the sulfuric acid solution obtained in step a. to form a solution containing ammonium sulfate and a treated, clean gas.

    摘要: A process for removal of heavy metals and/or dioxins from a fluid including heavy metals, where the fluid is brought in contact with a mixture including between 30% vol. and 60% vol. of an activated carbon catalyst impregnated with sulfur, between 30% vol. and 60% vol. of an activated carbon catalyst impregnated with iron and between 5% vol. and 40% vol. of a filler material, the total of these three ingredients being 100% vol, where the fluid is left in contact with the mixture, the heavy metals and/or dioxins are absorbed onto the mixture to obtain a fluid with a depleted level of heavy metals, which fluid is then evacuated from the mixture.
