A Belgian coal was subjected to non-catalytic liquefaction with tetralin as a hydrogen donor solvent in a magnetically stirred 500cm3 autoclave (no. I) and a 70cm3 autoclave which was shaken horizontally (no. II). At 425"C, coal conversion in both autoclaves increased when the tetralin/coal ratio wa
