A reactor/purifier for generating pure hydrogen in a stack or array of pairs of alternatingly connected high ( la ) and low ( lb ) pressure reactor chambers wherein a gas-porous turbulence-promoting screen structure washcoated with a steam-reforming catalyst ( 2 ) is sandwiched between a planar hydrogen-selective palladium alloy membrane ( 3 ) and a planar gas-impermeable heat-conducting metal plate ( 1 ) within the high pressure reactor ( lb ) chamber of each high pressure reactor chamber; and wherein the catalyst-coated structure ( 2 ) in each high pressure chamber ( la ) is reacted with steam and hydrocarbon fuel, such as methane or syn/gas, and/or carbon monoxide at an appropriately controlled temperature of between about 200°C to 650°C to produce hydrogen and carbon oxides within an isothermal temperature range in each high pressure ( la ) reactor chamber, while simultaneously permeating pure hydrogen therefrom through the membrane ( 3 ) into the corresponding connected low pressure reactor chamber ( lb ), and with the required heat transfer to and from the catalyst being provided in situ predominantly by conduction through the corresponding metal plate (1). |
