ABSTRACT OF THE DISCLOSURE A process for ammonia production includes preparing a hydrogen and nitrogen synthesis gas by autothermally reforming a hydrocarbonaceous feed, such as a hydrocarbon feed, with oxygen enriched air and steam in an autothermal reformer utilizing a first, monolithic catalyst having a palladium and platinum containing catalyst therein, and a second, platinum group metal steam reforming catalyst. The autothermal reformer provides a relatively simple and compact reactor within which a wide variety of hydrocarboneaceous feeds, from heavy hydrocarbon feedstocks to natural gas, may be utilized for the synthesis process, which is advantageously carried out at an elevated pressure. By controlling H2O to carbon, O2 to carbon, and N2 to carbon feed ratios, a given feed can be autothermally reformed to yield a synthesis gas of desired ammonia synthesis ratio of about 3:1 H2:N2.
