Short residence time hydropyrolysis of carbonaceous material

摘要

A process for treating carbonaceous material with hydrogen including adding the carbonaceous material into a first reaction zone of a reactor having at least two reaction zones; adding hot hydrogen to the stream of carbonaceous material to effect a reaction with same to produce reaction products; quenching the mixture while insuring that the total residence time varies from about 2 milliseconds to about 2 seconds; removing at least a portion of the reaction products from the quenched mixture; and introducing the residual carbonaceous material into a subsequent reaction zone and repeating the steps for the subsequent reaction zone.
