Fundamental Approach to Characterization and Processing of Coal-Derived-Liquid (CDL). Sixth Quarterly Report, December 1985-February 1986

摘要

Adsorption thermodynamic properties of nearly fifty model compounds have been measured. Data are being used to develop a model to predict adsorption equilibrium based on molecular structure. Molecular weight is shown to be a major influence on both heat of adsorption and entropy of adsorption. Additional contributions to heat of adsorption are observed from aromatic rings and hydrogen bonding. Particularly strong interactions are observed with basic nitrogen compounds. The model is based on a group-additivity concept. The model is being used to predict the adsorption of a 250 to 375 sup 0 C distillate from SRC-II coal derived liquid. These results are being compared with those derived from catalytic hydroprocessing of the distillate. 10 refs., 6 figs., 1 tab. (ERA citation 12:003307)
