Abstract
PURPOSE: The title additive free of sedimentation of pulverized coal even after long- time storage, prepared by adding a specific additive to a pulverized coal-oil mixture comprising a pulverized coal and water in a specific proportion.
CONSTITUTION: One wt.% or less of an additive comprising one or more types of compounds selected from (A) an organic compound having suforic acid and/or sulfuric acid groups in the molecule to give the total number of the groups of 2 or more in the form of acid or salt of counter ions, (B) a salt of an organic compound having plural carboxyl groups in the molecule or that of counter ions, and (C) cellulose, starch, natural rubber, or alginic acid derivatives is added to a pulverized coal-oil mixture (D) comprising 20W70wt.% of pulverized coal having an average particle size ≤ 200μ and 7wt.% or less of the total moisture ( the moisture added being 3wt.% or less ). The mixture (D) is obtained by pulverizing coal in an oil, and by heating at 50W200°C and applying vigorous agitation at a shear rate of 2m/sec or higher in any stage of manufacturing process
