Viscosity changes of coal slurry (1-methylnaphthalene as a solvent) during the catalytic hydroliquefaction were studied. A remarkable increase in the viscosity of slurry at 540K was observed for Pittston (highly coking coal), irrespective of the type of catalyst employed. Increases in the viscosity at 610K were observed for weakly coking Illinois No.6 coal, in the presence of an iron or a molybdenum catalyst. Increases in the viscosity for Pittston coal is considered to be associated with swelling behavior of the coal. However, those observed for Illinois No. 6 coal are considered to be related to coal degradation process.
