Characteristics of coal liquids hydroprocessed in continuous hydrotreater
Coal liquids hydroprocessed in a continuous hydrotreater over Ni-Mo catalysts under varying process severities were characterized to study variations in chemical constituents and physical properties of the coal liquids. A 30 to 70% blend of SRC-I and SRC-II distillate (435 to 665/sup 0/K) produced from Western Kentucky bituminous coal was used as feedstock for the hydroprocessing. Nitrogen removal was found to accompany hydrogen addition to aromatics in the coal liquid. The linear plot of nitrogen removal versus hydrogen consumption for reference catalysts was found to provide a useful reference for evaluating nitrogen removal activity and the hydrogen utilization efficiency of a new catalyst. Hydrotreating was found to drastically reduce the phenolic OH and carbazolic NH content and reduce the heteroatoms, asphaltenes, and aromatics while at the same time increasing the aromatics and alkyl aromatics.
