  • Short residence time hydropyrolysis of carbonaceous material
    Patent number: 4003820
    Abstract: 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.
    Type: Grant

  • Coal hydrogenation to produce liquids
    Patent number: 3960700
    Abstract: Crushed coal is mixed with hot hydrogen, at 500.degree. to 1,500.degree.C. and 600 to 3,000 psig., in a reactor, and then, after a short reaction time, rapidly quenched. The total heat-up, reaction, and quench time is less than 2 seconds. This short residence time results in less gas production and less polymerization of the liquid components.
