The previous report concerned the effects of blending different types of coal on the catalytic hydrogenation reaction. This report describes results obtained by blending Shin-Yubari coal with Yallourn brown coal or Taiheiyo coal or Sohyakoishi coal at various ratios on the hydrogenation reaction in the absence of catalyst.<BR>Due to the interaction of the two coals in the blends, there was a significant decrease in conversion compared to the predicted value when Yallourn brown coal was blended with Shin-Yubari coal. There was a slight decrease in conversion with the other blends. The principle reason was thought to be the hindrance of hydrogen diffusion in the blend due to the liquefied oil and unreacted material from Shin-Yubari coal. While a positive interaction under condition of sufficient active hydrogen availability was previously observed, it was observed that a negative synergism occured under the opposite condition of an insufficient supply of active hydrogen.
