Abstract
The urgent problems of decarbonization in the power-generating sector are analyzed, along with the potential routes to solve ecological problems connected with CO2 evolution from the combustion of coal - one of the major kinds of fuel for power generating facilities in the world, and especially in Russia and in Kazakhstan. The technology and equipment of the technological line for low-temperature (not higher than 75 °C) hydroconversion of power-generating coal into high calorific (heat of combustion 45 MJ/kg), ecologically safe (purified from ash) liquid hydrogenated coal fuel (HCF) with low carbon content (less than 45 %) are described. The methods for processing coal fuel in the form of water-coal suspension are considered. The routes to conserve the coal industry are discussed, relying on the production of hydrogenized coal fuel with low prime cost from power-generating coal, which will ensure technologically efficient and ecologically safe transition to low-carbon power engineering with zero greenhouse gas emission.
