Title: Fundamental approach to characterization and processing of coal-derived-liquid (CDL). Seventh quarterly report, March-May 1986. [Distillates from SRC-II coal liquids]

Technical Report ·
OSTI ID:7257385

Adsorption thermodynamic properties of nearly fifty model compounds have been measured. Data have been used to develop a model to predict adsorption equilibrium based on molecular structure of the adsorbing species. Molecular weight has a major influence on both heat of adsorption and entropy of adsorption values. Additional contributions are observed from aromatic rings and polar (hydrogen bonding) functionalities. The model has been used to predict the adsorption of three fractions distilled from SRC-II coal-derived-liquid (CDL). Theoretical considerations of the steady state composition of surface adsorbed species in a flow system reveal that with a broad boiling range material only the heaviest portion is adsorbed on the catalyst. These findings have major implications to catalytic processing of CDL. The results of the adsorption measurements and from the theoretical considerations will be related to kinetics derived from catalytic hydroprocessing of the distillates. 11 figs, 6 tabs.
