Abstract

B r o w n Coal Liquefaction (BCL) process had been developed through the
construction and the operation of 50 T/D pilot plant Ill Australia (1985-1990) by
KOBE STEEL Group. After the successful completion of the Pilot Plant Project,
newly Improved BCL process has been developed1). The feasibility study on
the commercialization of coal liquefaction plant in Indonesia has also been
carried out under the cooperation with BPPT supported by NEDO Limonit
ore (α-FeOOH) can be used as an industrial catalyst for direct coal liquefaction
with its high activity and low production cost. In this paper, the catalytic activities
of Indonesian limonit ore, Soroako Limonit were examined using a gas flow type
autoclave comparing with the other iron catalysts for the liquefaction of
Indonesian brows coal. It appeared that the Soroako limonit has a high
catalystic activity while finely pulverizing to sub-micron particle size can be
done economically. It can be concluded that Soroako limonit is one of most
suitable catalysts for the coal liquefaction plant constricted in Indonesia in the
fut-ure.
