摘要：

Kansk-Achinsk lignite hydrogenation in tetralin, isopropanol, ethanol and methanol was studied. Tetralin was the most active solvent. Synergetical effects were observed when the mixture of tetralin and alcohols was used for liquefaction. The variations in liquid product composition were analysed by a mechanistic numerical model incorporating two competing reactions: alkylation and hydrogen donation. The effect of preliminary O-methylation with (CH3)2SO4, reduction with LiA1H4 and with K/isopropanol and reductive methylation with K/CH3J on the oxygen functional group composition and liquefaction behaviour were examined for three coals with different rank. Coal pretreatments were shown to cause dramatic effects on the oxygen-containing group distribution. The liquefaction reactivity with methanol in the presence of ZnCl2 and NaOH catalysts decreased slightly. The liquefaction behaviour is strongly influenced by coal rank-
