Abstract

An analysis of identifying a derivative product of liquefied coal model
hydroprocessing was conducted. For that purpose, an integration gas
chromatography flame ionization-nitrogen phosphorous detector and mass
spectrometry (GC-FID/NPD/MS) was used. Hydroprocessing process was
performed by vibrating micro autoclave tipe batch using Ni-W/Alumina catalyst
under initial hydrogen pressure 6 MPa, reaction temperature 375oC and one hour
retention time. The analysis result showed that the predominant reaction were
hydrogenation, hydrodenitrogenation (HDN) and hydrodeoxygenation (HDO).
The HDO of methyl phenol and ethyl phenol took place faster than the other
hydroprocessing reactions such as HDN of quinoline and aromatic hydrogenation
(butyl benzene, naphthalene, phenanthrene dan pyrene). This indicates that the
hydrogenation reaction or the cleavage of C-O bonding took place very fast that
alkyl could not be detected in the oil. The HDN reaction or the cleavage of C-N
took place slower but the the nitrogen containing compound vanished faster due
to selective adsorption of the catalyst. However the hydrogenation reaction of
mono-aromatic took place faster than poly-aromatic
