Abstract

An effect of two different residue for liquefaction of Central Banko coal is
disccused. The residue was obtained from side-stream of refinery plant, which
so-called long residue and short residue solvents. The liquefaction test was
carried out under the reference conditions that have been developed in BPPT
coal liquefaction laboratory, at temperature of 450oC and initial H2 pressure of
12MPa for 1 hour. The result shows that the distillate yield, Bottom (BTM) yield,
and hydrogen consumption were dependent on the nature of solvent. Short
residue solvent shown higher reactivity than the long residue. Reaction between
Central Banko and Short Residue gave distillate yield higher than the long
residue. Moreover, its BTM yield was also lower than that of long residue solvent.
This result confirmed the lower hydrogen consumption for reaction short residue
and Central Banko coal compared to that for reaction long residue and Central
Banko. In this study, it also confirmed that the yield of H2O and CO+CO2 were
dependent on the material input condition. However, the yield of hydrocarbon
gases (C1~C4) was mainly affected by de-alkylation in the solvent and coal during
the reaction
