摘要：
Filtration of coal digest can be greatly facilitated by liquid phase extraction using an aromatic solvent oil of coal in at leasttwo stirred reactors in series. Control of residence time is greatly enhanced, reducing or eliminating short residence time digest components which increase filter cake resistivity and long residence time components which have repolymerised and cause loss of yield.
