【摘要】 分析了4个温度下水热处理对不同变质程度煤加氢液化反应性的影响。结果表明:(1)200℃~250℃为褐煤和长焰煤加氢液化较好的水热处理温度。(2)在实验条件下,水热处理温度200℃~250℃,褐煤总转化率和油、气产率可达到84.70%和79.29%,沥青烯和前沥青烯产率为5.41%;长焰煤相对应的数据分别为78.2%、70.72%和7.48%。(3)水热处理温度>250℃或<200℃,褐煤和长焰煤液化反应性均降低。更多还原

【Abstract】 The impact of the hydro-thermal treatment on hydrogenation liquefaction reaction of the coal metamorphosed in different degrees was analyzed.The result showed that(1)the preferable hydro-thermal temperature for the hydrogenation liquefaction reaction of the lignite and long-flame coal was 200 ℃-250 ℃;(2)at the experimental conditions,i.e.the hydro-thermal treatment temperature was at 200 ℃-250 ℃,the total conversion rate of lignite and the oil/gas production rate were 84.70% and 79.29%,respectively,the production rate of asphaltene and preasphaltene was 5.41%;the corresponding data of long-flame coal was 78.2%,70.72% and 7.48%,respectively;(3)in case the hydro-thermal treatment temperature was greater than 250 ℃ or less than 200 ℃,the liquefaction reactivity of the lignite and long-flame coal decreased.更多还原
