在钴钼催化剂存在下，在连续搅拌釜式反应器中，用氢气处理北达科他州褐煤在蒽油中的浆料。对所获得的褐煤溶解数据进行了动力学分析。已发现溶解速率在初始褐煤浓度中为一阶，在分数转化中为约十分之四阶。结果表明，表观活化能随着温度的升高而增加，其值为19至33千卡/克摩尔。
A slurry of North Dakota lignite in anthracene oil has been treated with hydrogen in a continuous stirred tank reactor in the presence of a cobalt-molybdenum catalyst. A kinetic analysis of the lignite dissolution data obtained has been carried out. The rate of dissolution has been found to be first order in initial lignite concentration and approximately four-tenths order in fractional conversion. Results indicate that the apparent activation energy increases with increasing temperature with values from 19 to 33 kcal/g mole.
