METHOD FOR PRODUCING COAL MIXTURE AND METHOD FOR PRODUCING COKE

WIPO Patent Application WO/2020/195863

A1

Provided is a method for producing a coal mixture, which is a simple method and which can suppress a decrease in coal fluidity better than conventional methods. In this method for producing a coal mixture in which a plurality of types of coal are mixed, formula (1) and formula (2) are satisfied. Formula (2): αcalc ≤ 1.2×10-10 (mol/g-coal) In formula (1) and formula (2), αcalc is the hydrogen ion release capacity (mol/g-coal) of the coal mixture per unit mass, αi is the hydrogen ion release capacity (mol/g-coal) of a coal i per unit mass, xi is the blending proportion of the coal i blended in the coal mixture, and N is the total number of types of coal contained in the coal mixture.
