摘要：

Three Spanish low rank coals, including a brown lignite, a black lignite and a subbituminous coal, and a German bituminous coal were liquefied for 1 h in a stirred autoclave with tetralin. The influence of temperature on conversion was studied from 300 to 475°C observing retrogressive reactions at T > 450°C. A study of the influence of rank on liquefaction has been made, finding an increase in conversion as rank decreases. A comparison of these results with those of others investigators is presented. Linear correlations between liquefaction yields and H/C ratios and volatile matter are established. © 1990.
