Rheological characterizations were made for a coal liquefaction preheater slurry; measurements were made in line at high temperature and high pressure. Above 400/degree/K, the coal-solvent slurry (35 wt.% coal) was pseudoplastic and was adequately modeled by a power-law equation. Experimental data over a temperature range of 400 to 700/degree/K were correlated, and critical slurry velocities for transition from laminar flow were calculated for flow in several pipe diameters. 15 refs.
