Process for manufacturing a hydrogen-containing synthesis gas from a natural gas feedstock, comprising the conversion of said natural gas into a raw product gas and purification of said product gas, the process having a heat input provided by combustion of a fuel; said process comprises a step of conversion of a carbonaceous feedstock, and at least a portion of said fuel is a gaseous fuel obtained by said step of conversion of said carbonaceous feedstock, and the Wobbe Index of said fuel is increased by a step of carbon dioxide removal or methanation.

Process for the synthesis of ammonia comprising the steps of reforming of a hydrocarbon feedstock into a raw product gas, purification of said raw product gas obtaining a make-up synthesis gas, conversion of said synthesis gas into ammonia; said purification includes shift conversion of carbon monoxide into carbon dioxide and the reforming process requires a heat input which is at least partially recovered from at least one of said step of shift conversion, which is carried out with a peak temperature of at least 450° C., and said step of conversion into ammonia.

A process for production of ammonia includes: providing a reaction stream including carbon monoxide and hydrogen; passing the reaction stream and steam over a water gas shift catalyst in a catalytic shift reactor, forming a shifted gas mixture depleted in carbon monoxide and enriched in hydrogen; passing the shifted gas mixture with an oxygen-containing gas over a selective oxidation catalyst at ≧175° C., forming a selectively oxidized gas stream with a portion of the carbon monoxide converted to carbon dioxide; removing some of the carbon dioxide from the selectively oxidized gas stream in a carbon dioxide removal unit; passing the carbon dioxide depleted stream over a methanation catalyst in a methanator to form a methanated gas stream, optionally adjusting its hydrogen:nitrogen molar ratio to form an ammonia synthesis gas; and passing the ammonia synthesis gas over an ammonia synthesis catalyst in an ammonia converter to form ammonia.

Provided herein is a gas mixer for the safe mixing of a hydrocarbon containing gas with a gaseous oxidant. The gas mixer and method for mixing described includes a closed mixing vessel where bubbles of gas injected at the bottom of the vessel are mixed during their rise to the top of the vessel, forming a homogeneous mixture that can safely be removed. This simple design and method allows for safe mixing of gases and is applicable to catalytic oxidative processes such as oxidative dehydrogenation of paraffins where there is a risk of thermal runaway of reactions.
