Flash hydrogenation is a short residence time (1 to 10 sec) gas-phase, non-catalytic process in which pulverized coal is rapidly heated (20,000-30,000° C/sec) in hydrogen to obtain liquid and gaseous hydrocarbons directly. Experiments were conducted in a 2 lb/hr, 1 ID x 8 ft long downflow tubular reactor in the range of 500° to 900°C and 500 to 3000 psi H2 pressure for North Dakota Lignite and New Mexico subbituminous coal (L). The ultimate analyses of these coals are given in... 

Details of the correlation for the lignite are reported elsewhere Q) For New Mexico subbituminous coal, data from 47 experimental runs, also with l /coal weight ratio of about 1, were correlated. For these runs, 166 data points, corresponding to different locations in the reactor, were available for CH4, C2H6 and BTX concentrations. Oil data, obtained from the total amount of oil collected in the condensors, were available for 17 runs.
