为了美国蒙大拿次烟煤的加氢液化,研究了一种新催化剂体系——金属氯化物浸渍在固体煤上,于5%HCl-H_2气氛中。在半连续的反应器中进行不同金属氯化物的初步筛选。最好的催化剂再在连续短停留时间的管式反应器中试验。当反应气体含有5%HCl时,油收率增加,约为没有HCl时的2倍到5倍以上,这取决于 For the hydrogenation liquefaction of Montana sub-bituminous coal in the United States, a new catalyst system, metal chloride, was impregnated on solid coal in a 5% HCl-H 2 atmosphere. Preliminary screening of different metal chlorides was carried out in semi-continuous reactors. The best catalysts were tested in tubular reactors with short residence times. When the reaction gas contains 5% HCl, the oil yield is increased, about 2 to 5 times higher than in the absence of HCl, depending on
