Abstract

Catalytic hydrotreatment of South Banko coal liquid (SBCL) middle distillate (b.p.
300 – 420 oC) was performed over NiMo sulfides catalysts. The hydrotreatment
was conducted in an autoclave of 50 ml capacity under the conditions of 340 –
420 oC, 60 and 120 min and initial hydrogen pressure of 5 – 10 MPa. The
hydrotreatment reduced the contents of all heteroatom species (S, N and O).
Sulfur species were easiest to be removed, while nitrogen species were most
refractory. Reactivities of some representative heteroatom species were
measured to find the refractory species in coal liquid by GC-AED. Carbon
supported catalyst was compared to alumina supported one confirming its higher
activity for hydrodesulfurization, hydrodenitrogenation and hydrodeoxygenation.
