✦ Synopsis
Catalytic activity of molten tin for coal hydrogenolysis was examined under a wide range of reaction conditions. It wasfound that molten tin catalysed mainly the asphalteneformation reaction. Thecatalyst showed almost no activity in gasification and oil formation. The yield of asphaltene exhibited a maximum when plotted against temperature, indicating a recombination reaction at higher temperatures. Hydrogen pressure had a significant effect on asphaltene formation. It is considered that the hydrogen pressure affects both coal fluidity and surface condition of the catalyst thus causing the change in the extent of contact between catalyst and coal.
