Pretreatment of lignite including drying of low rank coal is one of the most important processes for its utilization. Volume shrinkage and recovery of lignite have been measured with a swelling apparatus at 30℃. Dewatering with conc. H_2SO_4 is a reversible process, while conventional drying process is not with respect to volume changes. Volume changes during dewatering and drying process of lignite are responsible to the molecular association and inter- and intra- molecular bonding. Spin-spin relaxation times of proton in lignite molecules and associated water molecules are also providing the characterization during the dewatering and drying process.
