摘要：

A number of catalysts were prepared for the desulphurization process of tail gases. Their carrier was alumina oxide while the active phase was manganese. The catalysts were being tested in an lab apparatus. The effect of calcination temperature and process temperature of model gas (1 vol % of SO2 + 99 vol % of N-2) were studied. The increase in the desulphurization temperature up to about 500-degrees-C causes the efficiency of the desulphurizing yield to be increased, a further increase of the temperature process decreases the SO2 conversion. The DTA curves of catalysts after the desulphurizing process display the additional peak at a temperature of about 900-degrees-C being, perhaps, responsible for deactivation of the catalysts.
