For commercialization of coal liquefaction processes, blending of various types of raw coal will be an important consideration. In this report, Shin-Yubari coal, Taiheiyo coal, Sohyakoishi coal and Yallourn brown coal were blended in various ratios to investigate the effects of a mixture of two types of coal on the hydrogenation reaction. The conversion of the blended coals were compared to conversion obtained for each pure coal. A blend of Yallourn brown coal and Shin-Yubari coal exhibited a clear deviation from additivity and a positive synergism was observed. Brown coal requires hydrogen donor solvent to enhance its hydrogenation capability. It is considered that hydroaromatics derived from Shin-Yubari coal promote the hydrogenation reaction of Yallourn brown coal.
