Coal-methanol slurry and its production process

摘要

A coal-methanol slurry having excellent storage stability, transportability and combustibility has been provided by using coal particles having a maximum particle size not greater than 1,500 mu m and a cumulative particle size distribution specified with respective to particles of 74 mu m and smaller, 10 mu m and smaller and 3 mu m and smaller and controlling the concentration of the coal particles within a specific range defined in relation to the degree of carbonization of the coal employed. A useful and advantageous production process of the slurry has also been provided, featuring an addition of water and the timing of its addition.
