Patent ·
OSTI ID:6800995

In a process for agglomerating finely divided carbonaceous solids from an aqueous slurry containing from about 10 to 40 weight percent finely divided solids comprising finely divided carbonaceous solids and finely divided inorganic solids, comprising: (A) mixing the slurry with an amount of oil to produce agglomerates of the carbonaceous solids containing from about 10 to 15 weight percent oil; and, (B) recovering the agglomerates as a product, an improvement comprising: (C) admixing oil in an amount of about 40 to 70 weight percent based on the weight of finely divided solids with the slurry to produce a mixture; and, (D) mixing clean, finely divided carbonaceous solids with the mixture to produce agglomerates containing from about 12 to about 15 weight percent oi whereby an aqueous slurry containing finely divided carbonaceous solids which do not agglomerate upon the addition of from about 10 to 30 weight percent oil can be agglomerate
