Abstract

A coal liqueafaction test was carried out to investigate the reactivity of an
Indonesian brown coal, called South Banko, and an Australian brown coal, called
Yallourn. The liquefaction reaction was conducted to ascertain the effect of
reaction temperature on the reactivity of both brown coals and it represents on
the oil, CLB, CO+CO2 and C1~C4 yields. The result shows that South Banko coal
is more reactive than Yallourn coal. South Banko coal gives a higher oil yield
than that of Yallourn. Oil derived from South Banko coal increases as reaction
temperature rises. In contrast, oil derived from Yallourn decreased as reaction
temperature increased. This result indicated that South Banko has more labile
structure than that of Yallourn and it can easily break down the structure of South
Banko coal. In term of hydrocarbon gas, Yallourn produces higher yield than that
of South Banko. This suggests that Yallourn coal has alkyl groups in its structure.
It was also found that CO+CO2 yields are similar to both brown coals. South
Banko has less CLB yield than that of Yallourn but the CLB yield of South Banko
coal is higher than that of Yallourn while temperature is increased to 470oC. In
short, the study shows that South Banko coal is more reactive than that of
Yallourn coal and it is very potential for the coal liquefaction feedstock.
