Coal slurry was normally pumped at 500 ml. per minute leading to an average residence time in the mixer of 17 to 18 minutes. Since oil/coal contacting was complete in about 5 minutes, it is felt that the slurry feed rate could be, at least, doubled with no effect on product grade and recovery.
cleaner coal unsuitable for the Lurgi gasifiers. Hence, methods need to be evaluated which can beneficiate the coarser fractions of the coal, without reduction to fine sizes (smaller than 5 mm). Coal Beneficiation Technology Options For the beneficiation of coarse coal (larger than 56 mm), there are basically two wet
