摘要
A method of deashing coal wherein the coal is wetted with hydrocarbon liquid to form agglomerates and the hydrophilic agglomerates are then separated from a water and ash phase to yield deashed coal agglomerates. The hydrocarbon liquid is then recovered from the coal agglomerates by a vacuum stripping in the absence of oxidizing gases with or without use of super heated steam. Where super heated steam is used the removed hydrocarbon liquid is subsequently separated from the steam by cooling.
