ABSTRACT:
In an integrated process for the production of synthesis gas, a partial oxidation unit and a steam methane reformer are used to convert natural gas or another fuel to first and second mixtures of at least carbon monoxide and hydrogen, only the first process consuming oxygen. Carbon dioxide derived from the second mixture is sent to the inlet of the first process to reduce the oxygen consumption. The first and optionally second mixtures may be used as synthesis gas for a process such as a Fischer Tropsch process.
