The present invention provides an improvement in a process for the preparation of hydrogen and a carbon monoxide-rich gas by steam reforming of a hydrogen-rich gas in the presence of a steam reforming catalyst. The improvement comprising the essential steps of passing a heated, prereformed hydrogen feedstock through a second tubular reactor which is provided with a thin film of the steam reforming catalyst, and which is heated by the burning of fuel, thereby to obtain a partially-steam-reformed gas effluent and hot flue gas, passing the partially-steam-reformed gas effluent through a fixed bed, steam reforming catalyst, and withdrawing a product gas stream comprising hydrogen and a carbon monoxide- rich gas from the fixed bed.
