The influencing factors analysis of direct liquefaction product of YuXian Bituminous Coal
Abstract：With the analysis of direct liquefaction product under high temperature and high pressure of Yuxian bituminous coal, it is found that after the addition of high dispersion of iron catalyst which is developed independently by China, the product could obtain a higher rate of oil yield and coal conversion （respectively 51.73% and 83.9% ）. The Consumption of H2 in the Liquefac- tion unit of this experiment is only 6. 12% , which is obviously less than typical process abroad. The result will lead to a cost advantage and a throughput increase of the experimental device. Meanwhile, the experiment shows that the reaction pressure is as low as 19MP and the reaction condition is milder. As a result, the experiment will be much safer. And the test requirements of experimental equipment and the operation cost will decrease greatly.
