Study On The Hypercoal Process For Brown Coal Upgrading

May 16, 2007 The Hyper-coal process is a coal refinery process that makes an ash-free coal by thermal extraction and solid-liquid separation technology. This study investigates the upgrading of brown coal by applying the Hyper-coal process. Several kinds of bituminous, sub-bituminous, and brown coals were thermally extracted with 1-methynaphthalene using a high temperature-extraction/filtration unit.
