FIELD: chemistry.
SUBSTANCE: formulation of a gas desulphurisation adsorbent contains two components, the first of which is a natural material and contains 47-87 wt % of manganese dioxide, whereas the second component represents expanded vermiculite produced by the thermal treatment of natural slate in an amount of 1-30 wt %. The first component is specified in ferro-manganese nodules, and/or manganese peroxide, and/or cryptomelane.
EFFECT: invention enables improving consumption parameters, extending the range of using the adsorbent in the area of gas flow purification with the low acceptable pressure difference and wet gas flows, eliminating the dust-like particle entrapment by the purified gas flow, as well as improving technical-and-economic indexes of gas desulphurisation.
