Abstract

A process with its device for the catalytic synthesis of ammonia, from 300º to 500ºC and under a pressure of between 100 and 450 kg/cm2, on a single adiabatic layer of an iron-based catalyst, whose process comprises direct recycling towards the entrance of said layer of an amount comprised between 30% and 80% of the gases leaving the layer and containing at least 12 mol% of ammonia, the difference (δ s) being between the percentages ammonia molars in the gases that leave said layer and that respectively penetrate it from 3% to 6%.
