Heteroatom compounds in coal liquid distillates were analyzed by GC-AED to identify thier structures and to classify their reactivities in catalytic hydrotreatments with NiMo supported on alumina under the conditions of 360-450℃ and 30-120min at the hydrogen pressure around 15MPa. All the heteroatoms (N,S, or O)-containing compounds were detected and distinguished by GC-AED, and some of them were identified by using standard samples and Gc-MS. The hydrotreatment reduced the contents of all the heteroatoms, the removal conversion being in the order of S>O≧N. The higher temperature and hydrogen pressure enhanced the denitrogenation reactions. It is pointed out that the extent of hydrogenation of the produced oil should be important and well correlated to the heteroatoms (especially N and O) removal.
