Characterisation of the products of low temperature pyrolysis of Victorian brown coal in a semi-continuous/flow through system
Qi, Ying; Han, Will; Subagyono, RR Dirgarini; Fei, Yi; Marshall, Marc; Jackson, W. Roy; Patti, Antonio F.; Chaffee, Alan L. (Elsevier BV, 2018-07-24)Two Victorian brown coal samples, a run-of-mine Loy Yang coal (LY) and a Loy Yang light lithotype (LL), were subjected to pyrolysis at 420–460 °C and 330–460 °C, respectively, under a continuous nitrogen flow. The process ... -

Subagyono, RR Dirgarini; Marshall, Marc; Jackson, W. Roy; Fei, Yi; Chaffee, Alan L. (American Chemical Society, 2015-12-04)Our previous work suggested that liquid product yields from wood, unlike those from other biomass types, were not increased by CO/H2O reaction. Reactions of blue gum (BG) and fossil wood (FW) using high-temperature, ... -
