THE COMPARATIVE ANALYSIS OF THE EFFICIENCY OF CATALYST ACTIONS DURING THE PYROLYSIS OF LOWLAND PEAT AND BROWN COAL
The article is devoted to the problem of the thermochemical proceeding of low-quality solid combustible minerals, and in particular, the influence of the catalysts of different nature on the depth of the conversion of organic matter. A comparative analysis of the influence of different by nature salts transitive metals - cobalt, nickel, iron and manganese on the output of stationary pyrolysis products from peat and brown coal was conducted, the composition of pyrolysis gas and solid residue was determined. The presented results confirm the revealed tendency - the acceleration of the thermal decomposition of organic matter in peat and brown coal using selected catalysts, which form the following series in the terms of a following raw: FeCl<sub>3</sub> > MnCl<sub>2</sub> > NiCl<sub>2</sub> > CoCl<sub>2.</sub> Thus, catalytic pyrolysis allows to increase the degree of organic matter conversion with comparable energy consumption for its implementation. Moreover, the use of the catalysts of different nature can not only increase the depth of the thermal transformation of the organic matter of caustobioliths, but depending on the goal, to obtain in a preferential degree either a gas component or a solid phase, in the structure of which a certain metal catalyst can be embedded (impregnation) and impart given properties for the purpose of the subsequent formation of selective properties when active carbons are obtained from it.
