Aerospace technology has been successfully applied, in a DOE sponsored program, to the urgent national goal of coal conversion to liquid and gaseous fuels. The adaption of rocket reactor technology to the direct hydrogenation of pulverized coal has resulted in a new generation of coal conversion reactor technology which can be used to efficiently produce a wide array of liquid and gaseous fuel products. Liquid rocket injection/mixing techniques are used to very rapidly mix streams of pulverized coal and hot hydrogen to implement a direct hydrogenation reaction in a matter of milliseconds. The amount of reaction time determines the product mix. Reaction times have been varied from 33 to 600 milliseconds producing mainly liquid products at the shorter residence times and synthetic natural gas at the longer residence times. Continuing development of this process could result in the early and economical conversion of some of our plentiful coal supplies to much needed liquid and gaseous fuels. (DePo)
