Low-temperature pyrolysis of synthoil centrifuged solids. [5 refs]

Technical Report ·
OSTI ID:7219372
One of the steps in the SYNTHOIL process is a centrifuging operation to remove suspended particles of partially reacted coal and mineral matter from the coal liquefaction product. The solids that are separated by centrifuging are permeated with oil. As a method of oil recovery, the centrifuged solids were treated thermally at temperatures to 300/sup 0/C and at heating rates of 55 to 75/sup 0/C/minute. Appreciable quantities of oil, amounting to as much as 53 wt percent of the solids on an ash-free basis, were recovered. Spectrometric analyses of the recovered oil indicated that it contained lighter organic components and significantly less inorganic material than the centrifuged liquid.
