✦ Synopsis

Coal liquefaction residue characteristics were discussed. The heavy organic matter content and the ash content affect the viscosity of residue. A simplified kinetic model was developed that could estimate the heavy organic matter content of residue at some liquefaction conditions and its ash content could be calculated from its balance. The viscosity of the residue at some liquefaction conditions could be thus estimated. These estimations found fairly good agreement with experimental results.
