Abstract: A catalyst comprises a mixture of 95% vol. to 30% vol. of an activated carbon catalyst and from 5% vol. to 70% vol. of a filler material as well as a configuration of such a catalyst for the removal of SO2, heavy metals and/or dioxins form waste gas and liquids.

Abstract: 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.

Abstract: 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.

Abstract: A process where a gas, containing SO2 and O2 is brought in contact with a mixture of from 95% vol. to 50% vol. of activated carbon catalyst and from 5% vol. to 50% vol. of an inert filler material, where the SO2 is converted to H2SO4 on the activated carbon catalyst and is then washed from the activated carbon catalyst to obtain a H2SO4 solution.

Abstract: The present invention relates to a method for the catalytic removal of sulfur dioxide from waste gases in two reactors, wherein the first reactor is charged with an activated carbon catalyst. The method comprises: a. provision of a waste gas with a water content of less than 1 g H2O/Nm3 and an SO2 content of at least 5 ppm, b. introduction of the waste gases into a first reactor, c. catalytic conversion of the SO2 into gaseous SO3 in the first reactor by the activated carbon catalyst, wherein catalytic conversion on the activated carbon catalyst proceeds at a temperature of below 100° C., d. introduction of the prepurified waste gases from the first reactor into a second reactor, e. conversion of the SO3 with water into H2SO4 in the second reactor.

Abstract: The present invention relates to a method for the catalytic removal of carbon dioxide and NOx from waste gases in a reactor charged with activated carbon catalyst. The method comprises the following steps: a. saturating the catalyst with water b. saturating or partially saturating the waste gases with water, c. introducing the waste gases into the reactor, d. catalytically converting NOx into NO2? and, in parallel with this, catalytically converting CO2 into carbon and O2 on the same catalyst, e. washing out the activated carbon catalyst with water and discharging the carbon as a solid and NO2? dissolved in water or in the base.

Abstract: A method for the catalytic removal of sulphur dioxide and carbon dioxide from waste gases in a reactor charged with an activated carbon catalyst, includes saturating the activated carbon with SO2, saturating or partially saturating waste gases with water, introducing the waste gases with water, introducing the exhaust gases into the reactor catal ticall convertin the SO2 into H2SO4 and CO2 into C and O2 and into sulphur-carbon compounds on the same catalyst, washing out the catalyst and discharging the H2SO4 as a liquid and the C as a solid and/or bound to sulphur compounds.
