摘要：
In the reported investigation, the chemical compositions of the young coals of Sangar, formed by the clarain type of coal with a high yield of bituminoids and low-temperature carbonization tar, have been studied. A scheme for the multiple treatment of the Sangar coals has been put forward which provide for the production of wax from the bituminoids and, by the low-temperature carbonization of the coal freed from the bituminoids of semicoke as a smokeless power fuel and of tar as a raw material for the chemical industry.
