| abstract |
The invention relates to a process for the production of low-sulfur gas from crude gas, which has a higher content than the produced gas of sulfur-containing gas constituents, in particular H 2 S and / or SO 2 . The crude gas may contain hydrocarbons, for example methane, and be used for example as fuel gas. Alternatively, the raw gas may be, for example, exhaust gas, for example from the combustion of hydrocarbons and in particular having SO 2 as the sulfur-containing gas constituent. Desulfurization is achieved by generating a plasma in the raw gas while contacting the raw gas with a solid comprising a boride, bromide, bromate, carbide, carbonate, chloride, oxychloride, chlorate, perchlorate, fluoride, iodide, iodate, nitride, Nitrate, oxide, hydride or hydroxide of mono-, di- or trivalent cations and / or a hydrate of these compounds. |
