Fuderer, A

An improved process for the production of carbon monoxide by the steam reforming of hydrocarbons is described comprising: (a) catalytically reacting a fluid hydrocarbon feed stream with steam in a steam reformer; (b) passing the reformer effluent containing hydrogen, carbon monoxide and carbon dioxide from the steam reformer, without scrubbing to remove the carbon dioxide content thereof, to a pressure swing adsorption system having at least four adsorbent beds, each bed of which, on a cyclic basis, undergoes a processing sequence; (c) recycling the carbon dioxide-rich stream to the steam reformer for reaction with additional quantities of the hydrocarbon feed stream being passed to the stream reformer to form additional quantities of carbon monoxide and hydrogen, with product recovery being enhanced and the need for employing a carbon dioxide wash system being obviated.
