- The overall objective of this work is to demonstrate conversion of coal to produce at least 70% by weight of the coal as liquids, with ratios of liquids to gases in excess of 10/1, resulting in low hydrogen consumption and a significant reduction in the cost of producing hydrocarbon liquid fuels from coal. Utilizing a small continuous-flow reactor designed and constructed for this research, the maximum possible ratio of liquids to gases will be defined, operating at short residence times of a few seconds, at the same time converting more than 70% of the carbon in the coal to liquids. The practical ability to attain coal particle center-line temperatures of 500 °C in one second or less, using hot hydrogen gas in turbulent flow, will also be demonstrated. Particle heat-up rates for a few selected system pressures and particle sizes will be determined. Catalysts will be screened and selected for sufficient activity and selectivity. Particle heat-up rates for small coal particles slurried in a super-critical hydrocarbon-type fluid will be examined, using hot hydrogen gas in turbulent flow as the heat transfer medium.
