Abstract

This study of coal liquefaction in the absence of catalyst and solvent was
conducted. In this research a comparison of two different coals was carried out to
see characteristic of each coal on the liquefaction reaction. The effect of
hydrogen and CO/H2O were also checked to understand the mechanism of the
process. Lignite or brown coal from Tanjung Enim and sub bituminous coal from
East Kalimantan are used in this study. The results suggest that increase in coal
rank from lignite to sub bituminous did not alter the conversion significantly.
Surprisingly, the reduction in conversion of sub bituminous coal by its inorganic
and mineral content noted for hydrogenation reactions (with added tetralin) is not
observed in CO/H2O reactions. For lignite, there is a tendency for conversion to
increase.
Kata kunci: lignit, sub bituminous coal, non solvent hydrogenation
