Abstract

For the efficient use of gases formed in a number of thermochemical procedures of carbon processing, it is necessary to purify them from hazardous impurities, such as H2S, HCN, NH3, resinous substances. To purify the gases, it is proposed to use the liquid catalytic procedure with the soluble derivatives of cobalt phthalocyanine as a catalyst. This method allows achieving the required purification extent with low expenses. The purified gases can be used to obtain electricity and heat, and also as chemical raw material for obtaining ammonia, methanol, liquid fuel, etc. Elemental sulphur is obtained as a result of purification.
