Extraction of sulfur (IV) oxide, nitrogen oxides and carbon oxide from flue gases using a sorbent under conditions of its mechanical activation

Abstract

Abstract The paper substantiates the feasibility of creating an adsorption technology with controlled activation of the adsorbent for the removal of sulfur dioxide, nitrogen oxides, and carbon from the flue gases of coal-fired power plants. In laboratory conditions, the effect of mechanical activation on the adsorption capacity of ash was studied. It is shown that the controlled mechanical activation is able to increase the adsorption capacity of ash relative to sulfur dioxide by 2.7 times, to nitrogen oxides by 2.1 times, to carbon monoxide by 5 times or more.
