Pseudo Component Lumping of Softening Coal

Abstract

A pseudo component lumping analysis was made analyzing the free induction decays of high-temperature NMR of low rank coals into four components, i.e., a rigid component, an intermediate component and two mobile components (mobile component 1 and mobile component 2). It was found that the characterization using the amount of the mobile component 1 obtained by the pseudo component lumping analysis is more useful than that using the maximum fluidity (MF) obtained by the Gieseler plastmeter for low rank coals.
