Summary
Analyses of experimental data produced in a single-stage system for direct conversion of coal to a product containing more than 50% by weight of the coal as C₂C₄ gases, revealed that the conversion of coal to liquids occurs much more rapidly than the follow-on conversion of the liquids to hydrocarbon gases. The analyses revealed further that most of the hydrocarbon gases are produced from the coal-derived liquids, as opposed to direct production from the coal matrix. It is for that reason that it was deemed necessary to conduct experiments in two-stage reactor system, before a prototype reactor system could be designed. Large amounts of experimental data concerned with conversion of coal to liquids, including kinetic data, are already found in the literature. Primary interest namely production of C₂-C₄ hydrocarbons, therefore is focussed upon the conversion of the coal-derived liquids to C₂-C₄ gases. Since the first step of conversion of coal to liquids is not to be studied kinetically, that step of the overall process is performed in the simplest manner possible, utilizing a one-gallon autoclave. The liquids from the autoclave are then separated from the solids, consisting of unreacted coal, mineral matter, and catalyst when used, and the liquids passed to the second stage. Solids separation is performed by filtration.
