摘要：

The activity of hydrocracking catalysts used for the upgrading of coal extracts is reduced by mineral matter deposition. The influence of digestion and filtration conditions in a coal liquefaction process have been investigated to determine their effect on ash levels and trace elements in the extract solution. It has been shown that the digestion pressure has a significant effect on ash levels, while other conditions have little effect. Trace element proportions vary considerably from feed coal ash to extract solution ash with known deactivating species showing the largest increase.
