Adsorbents and catalysts based on carbon materials used to remove hydrogen sulphide from gases are reviewed. Alongside with traditional carbon-based materials, much attention is paid to using carbon nanotubes and nanofibres to prepare catalysts for selective oxidation of hydrogen sulphide to sulphur. The efficiency of purification from hydrogen sulphide using catalysts based thereon is much higher, and nitrogen doping of materials substantially improves characteristics of this process. The paper describes three base technologies for hydrogen sulphide removal. They are developed at the Boreskov Institute of Catalysis, Siberian Branch, Russian Academy of Sciences and are based on the use of the fluidized bed of the catalyst for selective oxidation of hydrogen sulphide and catalysts-sorbents in the fixed bed. The technologies were as follows: 1) treatment of acid gases from amine purification of associated petroleum gas; 2) purifying gases from blowing off sour crude oil, and 3) utilizing oxidation of hydrogen sulphide directly as a component of associated petroleum gas. Efficient carbon catalysts and sorbents are suggested to be used for the second-stage treatment of tail gas from facilities made according to base technologies.
