  • Patent number: 7060118
    Abstract: Process for the preparation of hydrogen and carbon monoxide rich gas by steam reforming of hydrocarbon feedstock in presence of a steam reforming catalyst supported as thin film on the wall of a reactor, comprising steps of (a) optionally passing a process gas of hydrocarbon feedstock through a first reactor with a thin film of steam reforming catalyst supported on walls of the reactor in heat conducting relationship with a hot gas stream; (b) passing effluent from the first reactor to a subsequent tubular reactor being provided with a thin film of steam reforming catalyst and/or steam reforming catalyst pellets and being heated by burning of fuel, thereby obtaining a partially steam reformed gas effluent and a hot gas stream of flue gas; (c) passing the effluent from the second reactor to an autothermal reformer; and (d) withdrawing from the autothermal reformer a hot gas stream of product gas rich in hydrogen and carbon monoxide.

  • Patent number: 6746624
    Abstract: Process for the preparation of hydrogen and carbon monoxide rich gas by catalytic steam reforming of a hydrocarbon feedstock comprising steps of: (a) optionally passing a process gas of hydrocarbon feedstock through a first reactor with a steam reforming catalyst heated by a hot gas stream; (b) passing the effluent from the first reactor to a subsequent tubular reactor containing a steam reforming catalyst and being heated by burning of fuel, thereby obtaining a hot gas stream of steam reformed product gas and a hot gas stream of flue gas; and wherein a reforming catalyst is placed on a metallic support having substantially the same shape as a wall of the reactor and being arranged in heat conduction relationship with the reactor wall.

  • Patent number: 5932141
    Abstract: The process of this invention prepares a hydrogen and carbon monoxide rich gas stream by passing a hydrocarbon feedstock mixed with steam to a tubular reaction with a thin layer of film of a steam reforming catalyst supported on the inner walls thereof; passing the effluent from the tubular reaction to a fixed bed steam reforming catalyst; and withdrawing from the fixed bed a hydrogen and carbon dioxide rich product gas, said tubular reactors being heated burning of fuel. Optionally, the feed to the tubular reactor herein designated the second tubular reactor, may be the effluent from a similar tubular reactor, herein designated the first tubular reactor in heat conducting relationship with hot flue gas from the second reactor.
