Abstract
An improved heat utilization in catalytic steam reforming of hydrocarbons to form a product stream rich in hydrogen is obtained by (a) first passing the process gas through a first portion comprising 25-75% of the steam reforming catalyst, whereby the heat needed for the endothermic reactions during reforming and for heating the process gas is supplied partly from a moderately hot flue gas and partly from the product stream; after which (b) the partly reformed process gas is passed through the remaining portion of the reforming catalyst, the heat needed for the further endothermic reactions and for heating the process gas is supplied by a hot flue gas generated by combustion of a fluid fuel, the hot flue gas being thereby cooled to form the moderately hot flue gas mentioned under (a). A reactor for use in this process is also described.
