Abstract

Catalytic hydrotreatment of South Banko coal liquid (SBCL) distillates was
studied through single and two-stage hydrotreatment over a commercial
NiMo/Al2O3 catalyst. The hydrotreatment was conducted in an autoclave of 50 ml
capacity under the conditions of 360 – 450 oC and 30 – 120 min at initial
hydrogen pressure of 10 MPa. The hydrotreatment reduced the contents of all
hetero-atom species (S, N and O). sulfur species were easiest to be removed
even at low temperature of 360 oC. In contrast nitrogen species were most
refractory. The higher temperature and more amount of catalyst enhanced the
denitrogenation reaction. The two-stage hydrotreatment was more effective for
the denitrogenation and deoxygenation because of the fresh hydrogen in the
second stage and the combination of lower and higher reaction temperature at
each stage.
