Claim Text:
1. Process for the production of synthesis gas from a hydrocarbon feedstock, comprising the steps of: a. reforming at least a portion of said hydrocarbon feedstock in an endothermic reforming stage in a heat exchange reformer and withdrawing from the heat exchange reformer an effluent stream of primary reformed gas; b. passing the primary reformed gas from the heat exchange reformer through an autothermal reforming stage (ATR), catalytic partial oxidation stage (CPO) or partial oxidation stage (POX), and withdrawing a stream of hot effluent synthesis gas; and c. splitting the hot effluent synthesis gas into at least a first synthesis gas stream and a second synthesis gas stream, wherein said first synthesis gas stream is used as heating medium in indirect heat exchange in the heat exchange reformer of step (a) with an exit temperature in the range of from 450-800° C.; and wherein said second synthesis gas stream is directed to a second heat exchanger and cooled by indirect heat exchange to produce a cooled second synthesis gas stream.
