The sedimentation rates of benzene insoluble matter (BI) obtained from liquefaction of Taiheiyo and Moura coals were measured in benzene by adding n-alkanes (methane, ethane, propane and butane) as anti-solvent. The sedimentation rates for both BI were remarkably accelerated by adding propane and butane, but not by adding methane and ethane. The sedimentation rate for Moura BI was faster than that for Taiheiyo BI by adding n-alkanes.
