Abstract

A method of improving the mechanical resistance of coke comprises forming a liquor of fine grained coal and oil with the oil being of from 5% to 30% of the total weight, forming coal pellets of the liquor at an increased temperature of from approximately 80.degree. to 100.degree. C, and heating the pellets to transform them into coke in a known coking process. Prior to being carbonized, the pellets are advantageously coated with a separating layer of a substance preventing agglomeration, such as hematite ore, lime, fine coke, etc.
