Abstract

A comparison of liquefaction characteristic of two brown coals (South Banko and
Yallourn coals) was studied. A 5L autoclave batch reactor was used under the
condition with temperature at 450 oC , reaction holding time 60 minutes. The
initial hydrogen pressure was varied to compare the effect of different reaction
pressure on the product perolehans. The oil yield for Banko Selatan and Yallourn
increased 6% and 18%, respectively, by increasing initial hydrogen pressure
from 10 MPa to 15 MPa. However in accordance with increasing pressure from
15 MPa to 20 MPa, the yield did not change remarkably. On the other hand, the
CLB perolehan was significantly decreased for both coals when the pressure was
increased from 10 to 15MPa. Moreover, the CLB yield was abruptly decreased
when the hydrogen pressure drastically change to 20Mpa. It was found that the
increasing reaction pressure only affected to the yield of hydrocarbon gas slightly
but remarkably influenced the CO and CO2 gas production for Yallourn coal but
not for South Banko coal.
