CHARACTERIZATION OP MEDIUM DISTILLATE CUT (100-230°C) OIL FROM HIGH-ASH "MINA DO LEÃO" BRAZILIAN COAL TAR

Brazilian coal tar oil has been characterized by combined spectroscopic and chromatographic methods. A coal tar cut (100-230°C) obtained from a Gasifier Plant operating with "Mina do Leau" high-ash coal was fractionated into ABN "acid-base-neutral"groups. Infrared spectra and ele...

description Brazilian coal tar oil has been characterized by combined spectroscopic and chromatographic methods. A coal tar cut (100-230°C) obtained from a Gasifier Plant operating with "Mina do Leau" high-ash coal was fractionated into ABN "acid-base-neutral"groups. Infrared spectra and elemental analysis of each fraction has demonstrated the success of the fractionation step. GC/MS analysis of the total cut before the ABN fractionation revealed only hydrocarbons present in the sample. However, after the pre-fractionation step several nitrogen containing compounds of environmental concern were positively identified by GC/MS in the tar bases fraction.
