In an improved ammonia production a purge taken from a recycle stream of a primary reactor is fed without compression over an ammonia synthesis catalyst comprising a transition metal, eg ruthenium, promoted by alkali or alkaline earth metal on a carbon support having a basal plane surface area of at least 100 m<2>/g, a ratio of BET surface area to basal plane surface area of not more than 5:1 and a ratio of basal plane surface area to edge surface area of at least 5:1 |
