✦ Synopsis

The role of hydrogen and hydrogen-donor solvents in the liquefaction of a Victorian brown coal without added catalyst and in the presence of iron-and tin-based catalysts has been studied. Results of an investigation of the effect of temperature and pressure on the conversion parameters, of independent studies of asphaltene hydrogenation, and of work with model ethers are described. A mechanism is tentatively proposed to describe the role of iron, tin and iron-tin catalyst systems based upon these results.

Slurries of Victorian brown coal in either tetralin (1:3) or a hydrogenated creosote oil (HKC 300) (1:3) were reacted with hydrogen in a continuous reactor system both with and without the addition of iron/tin based catalysts. The product yields and distributions from reactions using HKC 300 oil as
