ABSTRACT: This work is aimed at solving the problem on sorption purification of waste gases from sulfur dioxide on the wastes of phosphoric industry, i.e. thermophosphorus slags (TPhS). The solution of this problem is implemented by the new technical result, which is caused in increasing the depth of treatment by sulfur dioxide. Essential features of the claimed technical solution are the sorption purification of sulfur dioxide from waste gases on sorbent, containing layer of the granular TPhS. The experimental results showed that the highest activity of the sorbent, calcined at 500°C, is manifested at a temperature of sorption of 200 °C. With further increase of the process temperature, the degree of sorption does not change and duration of work of the sorbent is reduced.
KEYWORDS: Thermophosphorus slag; adsorption of SO2; catalysis; calcination; chemisorptions; activation of metal oxides
