An evaluation of the process requirements resulting from changing the Hydrane process from a two-stage hydrogenation to a single-stage hydrogasification process was undertaken by the Dravo Corporation for the Morgantown Energy Research Center, US Department of Energy, Morgantown, West Virginia. Hydrogenation is the reaction of coal with hydrogen to produce gaseous and/or liquid products. Hydrogasification is the gasification of coal by direct reaction with hydrogen to produce gaseous products only. The present single-stage process scheme has further developed hydrogasification to incorporate rapid heating of fine coal particles (70%, -200 mesh) to the reaction temperature (1600 to 2000/sup 0/F). The heating rate has been estimated to be in excess of 1 x 10/sup 60/K per second. The combination of the two foregoing operations, i.e., rapid heating of the particle in an atmosphere of hydrogen, results in devolatilization of the coal particles and rapid reaction of devolatilized hydrocarbons with hydrogen. This process has also been termed flash hydropyrolysis. The advantages which accrue to this process are: increased throughput, high methane yield, single pass and simple design.
