Abstract
The liquefaction behaviour of brown coal has been investigated using a reactor system that can be used to rapidly charge a coal slurry into a preheated autoclave and then sample its contents throughout the course of reaction. A comparison of the conversion activity for two brown coals of different atomic H C ratio has been performed. Differences are observed in the amount of oil liberated upon hot-charging, and in oil formed during the total reaction period. The results correlate well with a binary, guest-host structural model developed for low rank coals. A limited comparison with a bituminous coal has also been carried out.
