Abstract

PURPOSE: To produce oil-contg. deashed coal of extremely low ash content, by puluerizing raw coal, forming a slurry of the pulverized coal, adding a seed (nucleating agent) and a low-boiling oil to the slurry, and then treating the mixture.
CONSTITUTION: Raw coal is pulverized by a wet process to produce pulverized coal having a particle size of serveral tens W hundreds μm (at the same time ash contained in the coal is also pulverized). The pulverized coal is slurried in a proper amount of water. A low-boiling oil such as kerosine and a seed such as a particulate synthetic resin or coarse coal powder having a particle size of several μm, are added to the slurry of the pulverized coal to granulate them. The resulting granulates composed of the pulverized coal, the low-boiling oil and the seed are separated from the slurry and washed with water to remove ash. The granulates are dried to completely remove water. Then the desired product, pelletized deashed coal contg. the oil is separated from the seed. The fresh low-boiling oil is added to the recovered seed, and the mixture is recycled to the granulating stage.
