Nine hydrocarbons were blended with coals, and their effectiveness on coke strength was evaluated by several methods such as indirect tensile test and temperature-variable dynamic viscoelastic measurement. Peri-type polyaromatics enhanced the coke strength, and a good relationship between the coke strength and their boiling point was seen. On the other hand, cata-type polyaromatic and paraffin showed poor effect. The properties of additives to enhance the coke strength can be not only high fluidity but also high affinity to coal molecules.
