This paper reports results of an investigation which was undertaken in order to improve purification of liquid fuels obtained by coal liquefaction processes. It is shown that settling and filtration rates increased substantially after agglomeration. And, ground coal was found to be an economical substitute for diatomaceous earth in filtration. The effects of certain solvents on the agglomerating tendencies of solids in the unfiltered oil (UFO) from the SRC and COED processes were determined by oil immersion microscopy. The significant results obtained by these experiments are listed. Economic advantages are presented. 13 references.
