Novel dispersed catalysts for hydropyrolysis and low temperature hydrogeneration of coals

Stephens, H.P.

Results of fixed-bed hydropyrolysis and low temperature hydrogenation tests with a selection of coals and dispersed catalysts are described. Tar yields greater than 60% have been achieved in hydropyrolysis using sulphided molybdenum (Mo) with Mo concentrations as low as 0.1% daf coal for a number of bituminous coals. The hydrogenation tests indicated that the threshold temperature with these catalysts for oil generation from bituminous coals is 350{degree}C. 16 refs., 2 figs., 2 tabs.
