No.65 Coking properties of reforming coal produced by Thermal-hydrogenation processing of brown coal

Abstract

Our previous studies clarified that the thermal-hydrogenation processing of low rank coal results the elemental composition of reforming coal proceeds to the apparent area corresponding to the bituminous coal through dehydration, decarboxylation and methane removal reactions. Also the H / C and O/C change depending on the reaction conditions of coal reforming was revealed. In this study, along with morphological analysis by optical microscopy and chemical structure analysis by 13C-NMR, reforming coal obtained was evaluated by tests of coking by small test coke oven.
