Separation and characterization of coal derived components
Work is continuing on the detailed interpretation of the field-ionization mass spectra of eight hydroxyl aromatic oils and asphaltenes fractions from Wyodak and Kentucky SRC samples. It has become clear that the interpretation of the spectra will be complicated by the presence of nitrogen compounds in the fractions and the amount of oxygen in the fractions. After several chromatographic experiments, it was determind that tetrahydrofuran should be used as the solvent to inject preasphaltenes-1 onto a high-performance silica gel column to eliminate anomalous chromatographic peaks. Two SRC samples from Dr. Howard Silver were characterized by the Chromasorb T/basic alumina procedure and infrared spectroscopy. Experiments were completed on the collection of a large amount of high-performance liquid chromatographic data from model compounds. The data will be used for mobile phase optimization and prediction of retention. 3 figures, 2 tables.
