Abstract

PURPOSE: To provide a high-strength, high-reactivity, good-quality coke by a process wherein coals are hydrogenated in hydrogen atmosphere to be dissolved into hydrocarbon solvent, ash component is removed, and solvent is recovered to provide a reformed coal, which is compounded with raw coal for coke production.
CONSTITUTION: Coal such as caking coal, brown coal, and grass peat is mixed into hydrocarbon solvent such as dry distilled coal tar or its fractional distillation product so as to provide an approximate weight ratio of solvent:coal=1:1W10:1 and formed into slurry. The mixed slurry is heated at about 300W500°C under partial hydrogen pressure of about 10kg/cm2 to allow the coal to be dehydrogenated and dissolved into the hydrocarbon solvent. Then, undissolved solid is separated by a centrifugal separator, etc. and slovent is recovered by using an evaporator at about 250W450°C. The obtd. reformed coal having a 0.3W2wt% is compounded with raw coal for coke production thereby providing a required coke.
