Title:
PREPARATION OF COAL SLURRY
Document Type and Number:
Japanese Patent JPS6018585
Kind Code:
A
Abstract:

PURPOSE: To obtain coal slurry having such viscosity that it can be transported by pipeline, by blending coal particles adjusted to particle diameters in a specific range with a liquid to give slurry having a specific concentration.

CONSTITUTION: Coal particles having 5W95wt% cumulative weight ratio, having a particle size distribution adjusted in such a way that it obeys the formula [D is coal particle diameter(μm); D50 is coal particle diameter(μm)(5W500μm) at 50wt% cumulative weight ratio; F is cumulative weight ratio(wt%) of coal particle finer than coal particle diameter D; a is 2W5 in ≥D50 particle diameter range, and 1W3 in ≤D50 range particle diameter range] is blended with a liquid such as water, petroleum oil, methanol, etc. and the coal concentration is adjusted to ≥55wt%, to give the desired slurry.
