High pressure liquid chromatography (HPLC) provides a fast, relatively simple analytical method for analysis of the complex organic mixtures found in coal liquefaction processes. This technique offers distinct advantages over the more commonly used technique of gas chromatography. The feasibility of using HPLC to characterize products from liquefaction processes such as the Solvent Refined Coal (SRC) process are reported. Quantitation of chromatograms has been accomplished by assuming a Gaussian waveform and using a least squares method for computing peak areas relative to that of an internal standard. The effects of catalytic agents, namely, a commercial Co-Mo-Al catalyst, iron pyrite, mineral residue from the Wilsonville SRC pilot plant, coal ash, and process variables such as hydrogen partial pressure and temperature on the chemical composition of process solvent (creosote oil) and, also, of the liquid fraction of solvent/coal slurries during hydrogenation and hydrodesulfurization have been followed using HPLC. In so doing, the changes in composition of specific major constituents have been monitored with reaction.
