WEBOct 1, 1984 · Process slurries emanating from reactors generally contain 5 to 10 wt.% of solids. Solid—liquid separation processes must be used to separate the mineral residue and unconverted carbon from liquefied coal. Difficulties in removing those solid components represent a major obstacle to economic production of liquefied coal products.
