Abstract:	摘要： Raw coal of Khoot deposit and pyrolyzed coal samples were analyzed for ash content and composition, surface area and porosity, as well as thermal conversion characteristics in air atmospheres. The results confrm that the Khoot coal is a middle-rank sub-bituminous B-D mark coal. The porosity of raw coal, char of pyrolyzed coal or after thermolysis (thermal dissolution) was determined by scanning electron microscopes. The liquid tar product of thermolysis of Khoot coal was investigated by Fourier transform infrared spectroscopy, super(13)C and super(1)H nuclear magnetic resonance spectrometric analysis. The results of thermal dissolution of Khoot coal in tetralin with constant mass ratio between coal and tetralin (1:1.8) at 450 [degrees]C show that 61% of liquid product can be obtained after thermal decomposition of the coal organic mass. The char after pyrolysis was activated by heated water steam (called char-made activated carbon). The inherent physiochemical characteristics of sub-bituminous coal largely in 出版日期： 2015-01-01 出處： Journal of environmental engineering and management, 2015-01, Vol.25 (3), p.159-165 識別號： ISSN: 1022-7636 識別號： EISSN: 1022-7636
