Ammonia synthesis gas is produced by reaction of steam, an oxidant, and a major portion of fresh hydrocarbon feed in an exothermic catalytic reforming zone to a first reformed gas having very low methane content. The balance of the fresh feed is reacted with steam in an endothermic catalytic reforming zone to a second reformed gas having a low methane content. The first and second reformed gases are combined and passed in indirect heat exchange with reactants in the endothermic reforming zone to provide all of the heat required therein and are then recovered as raw ammonia synthesis gas.

Autothermal steam reforming process

Ammonia synthesis gas is partially converted over iron-based synthesis catalyst, cooled, and further converted over a more active synthesis catalyst.

Supplemental ammonia synthesis

The present invention is an improvement to a process for producing methanol which uses both steam reforming and partial oxidation by adiabatically reforming with substantially pure oxygen the reformed gas to produce the maximum amount of hydrogen for the synthesis of methanol.
