Estimating the term…
The inventive method for hydrogen sulphide and/or mercaptans decomposition consists in passing hydrogen sulphide and/or mercaptan-containing gas at a temperature less than 200° C. through a hard material layer (catalyst) which decomposes said hydrogen sulphide or mercaptans in such a way that hydrogen or hydrocarbons are released and sulphur-containing compounds are formed on a material surface. Said hard material is placed in a liquid medium layer. Said invention makes it possible to use a hard material (catalyst) without a periodical regeneration thereof.
A method for producing hydrogen and sulphur from a gas containing hydrogen sulphide and/or a mercaptan, said method comprising passing said gas at a temperature lower than 150° C. through a layer of a solid material capable of decomposing hydrogen sulphide and/or mercaptans with isolation of hydrogen or hydrocarbons and formation of sulfur-containing compounds on the surface of the material, characterized in that said solid material is placed in a layer of a liquid phase substance which is capable of dissolving intermediate reaction products and/or sulphur forming on the surface of the solid material.
