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

A process for dry coal hydrogenation-liquefaction has been developed that permits short residence times (seconds) and achieves notably high space rate utilization factors. The purpose of the work reported here is to identify more precisely the process variables that determine space rate utilization
Experimental kinetic data for three Australian coals are compared with predictions from the mathematical model developed in Part I. For these coals, as well as data reported for North American coals, the model is found to show good agreement, using the characteristic molecular weight as the only par
