Abstract
A hydrogen plant for producing hydrogen, including: a reforming reactor system including a first catalyst bed including an electrically conductive material and a catalytically active material, a heat insulation layer between the first catalyst bed and the pressure shell, and at least two conductors electrically connected to the electrically conductive material and to an electrical power supply placed outside the pressure shell, wherein the electrical power supply is dimensioned to heat at least part of the first catalyst bed to a temperature of at least 500° C. by passing an electrical current through the electrically conductive material, where the pressure shell has a design pressure of between 5 and 200 bar; a water gas shift unit downstream the reforming reactor system; and a gas separation unit downstream the water gas shift unit. A process for producing hydrogen from a feed gas including hydrocarbons.
