Abstract The process of lignite desulphurization via its treatment by an oxidant (air or air–steam mixture) has been studied. research objective was useful determination steam application in oxidative desulphurization. It proved that the water should be included composition to increase hydrogen sulphide and combustible constituent content gases obtained during processes under research. impact factors which affect reactions between solid (in our case – lignite) gaseous reagent (oxidant, i.e. air upon investigated, if these occur kinetic area. Such are linear rate movement coal grain size. values size, reaction transfer from pyrite sulphur organic diffusion into area occurs by, have determined. Under “transfer” conditions, coefficients mass ( β, m/s) as well Sherwood criteria boiling layer differences calculated.
