Pysh'yev S. Oxidized Desulphurization of High-Sulphur Low-Metamorphismous Coal

3. The thesis is dedicated to some questions of environmental protection and high-sulphur coal using as raw material for energy (power) and sulphur compounds obtaining. Selective oxidation of pyrite sulphur of low-metamorphismous coal via fluid process, which proceeds as a result of steam-air mix handling, has been in detail studied for the first time. The possibility of desulphurization gases obtaining with high sulphur dioxide content has been shown. It permits to remove the latter by one of known cyclic methods. The principles of "ecological purified" technology were elaborated. Principled scheme of the desulphurization coal process leading has been proposed.
