抄録

We have examined the validity of our new brown coal conversion process consisting of hydrothermal extraction and catalytic hydrothermal gasification both of which are operated at 300 to 350℃. Six kinds of low rank coals, Loy Yang (LY), Wara (WR), Berau Binungan (BB), Mukah Balingian (MB), Thai Lignite (TL), and Philippine Lignite (PL), were found to be extracted by 54, 48, 42, 40, 44 and 58 wt%, respectively, by water at 350℃. At 350℃, 97% of the LY extract was successfully gasified by our new Ni supported carbon catalyst, yielding CH_4 and H_2 in high yields. Through the hydrothermal extraction and the hydrothermal gasification, LY was converted into 53% of upgraded coal, 22% of CH_4, and 23% of CO_2 on carbon basis. In addition, 4.4mol of hydrogen was simultaneously generated from LY containing 100mol of carbon. This process transferred 95% of energy involved in the raw coal to the products at 350℃, showing its high thermal efficiency.
