Conversion of coal to liquid products occurs rapidly at temperatures over 350 C and can be significant in preheaters or short residence time reactors. The extent of conversion can have an effect on the operation of preheaters or effectiveness of subsequent reactors. To obtain process information, Illinois No. 6 coal in SRC II heavy distillate was reacted at 13.8 MPa, temperatures of 400, 425, and 450 C, and at slurry space velocities of 3200-96,000 kg/h-cu m. Product compositions and viscosities were measured. High concentrations of preasphaltenes occur in early reactions resulting in a high viscosity product, but subsequent reactions to asphaltenes and oils are less rapid.
