ABSTRACT:
Coal extracts from hydrogenative liquid extraction of coals can be more easily and more quickly filtered if the extraction is carried out at a temperature over 420.degree. C. and the resulting extract is fractionated using a cut point in the range 200.degree. to 300.degree. C. to remove low boiling material. The product is then filtered to give a filtrate containing less than 0.1% by weight of mineral matter.
