Abstract

A characterization of synthetic liquefied oil from coal was conducted to prepare
for further treatment of its quality. One of few techniques in improving the coal oil
is done through hydrotreatment process to remove its nitrogen, sulfur, oxygen
and aromatics contents known as heteroatoms which make the oil stability not
good. Experiment using small-scale fixed bed reactor shows there is an
improvement in the quality of recycle solvent used for coal liquefaction after first
hydrotreatment. coal slurry using first hydrotreated oil as solvent shows lower
viscosity than that of non-hydrotreated oil, and if mixed with coal from Banko, the
coal concentration could achieve as high as 50%. Nitrogen and sulfur contents in
hydrotreated oil are reduced to negligible level and the storage stability is
remarkably improved after hydrotreatment. The quality of fuel from second
hydrotreatment is still lower than that of petroleum productc in terms of ‘cetane
number’, ‘smoke point’, contents of sulfur and aromatics.
