Extraction of Brown Coals from Kansk-Achinsk and Lena Basins with Toluene and Water Containing Fluids
The conversion of different brown coals from the Kansk-Achinsk and Lena Basins in an aqueous
medium and in toluene containing mixtures with water and tetralin additives was studied under
supercritical conditions over the temperature range of 375-550 Β°C and at pressures from 7 to 40
MPa. It was found that the liquefaction of brown coals in the medium of toluene solvent with small
amount of hydrogen-donor tetralin co-solvent effectively occurred at low temperature 400 Β°C. On the
other hand, coal methanation, hydrolysis, and oxidation reactions with the predominant generation of
methane, carbon dioxide, and hydrogen prevailed in the water containing mediums. In a supercritical
toluene at 440 Β°C, the addition of a small amount of water (15 %) stimulated destruction of coals with
the predominant production of liquid products and moderate gas yields. The use of calcium oxide,
sodium hydroxide and hematite as the catalysts increased the yields of liquid products.ΠΠ·ΡΡΠ΅Π½ΠΎ ΠΏΡΠ΅Π²ΡΠ°ΡΠ΅Π½ΠΈΠ΅ Π±ΡΡΡΡ
