ABSTRACT:
A hydrogen rich gas such as pure hydrogen, ammonia synthesis gas, or methanol synthesis gas is generated by reacting steam with a nongaseous intermediate, whereby some of the steam is reduced to hydrogen and some of the intermediate is oxidized. Carbon dioxide may be added to or substituted for the steam, whereby carbon monoxide is produced in addition to or in lieu of H.sub.2. The oxidized intermediate is reduced by a reducing gas. The reducing gas is generated by partially reforming a light hydrocarbon such as natural gas or naphtha with steam and/or CO.sub.2, and then partially oxidizing the partially reformed gas with air. The low BTU exhaust gas resulting after reduction of intermediate oxide is used as fuel for the primary reformer. When ammonia synthesis gas is produced by this process, the purge and flash gases from the ammonia synthesis loop are added to the reducing gas.
