In this paper the influences of time, temperature and tetralin/coal ratio, as well as their interdependence, on the liquefaction behavior of a Spanish subbituminous A coal, are presented. The liquefaction experiments were conducted in 35 ml tubing bombs. Coal conversions were determined as weight % (toluene solubles + gases). There is an important influence of time and of temperature on coal conversion. There is also a relationship between the influences of these two parameters. On the contrary, the effect of tetralin/coal ratio is rather low. This may be attributed to the fact that with such a strong H-donor solvent as tetralin, and with the operating conditions used, hydrogen availability is not a critical parameter for the process.
