PROCESS FOR THE PREPARATION OF GASES WHICH CONTAIN HYDROGEN AND NITROGEN ABSTRACT OF THE DISCLOSURE : An improved process is disclosed for preparing gases containing hydrogen and nitrogen, especially suitable for the synthesis of ammonia. Using natural gas or virgin naphtha as the starting materials, the reforming reaction with steam takes place in two serially arranged stages, the first of which occurs at an inlet temperature of from 400°C to 650°C and an exit temperature of from 650°C to 750°C, a conversion of from 20% to 50% being effected, the second stage working at an exit temperature of from 750°C to 850°C and the conversion is now up to 70%. The air reforming is carried out at an exit temperature of the gas between 920°C and 1050°C and the sensible heat of the gases effluent from the air reforming at such temperature is exploited for actuating the second steam reforming stage. Tube bundle heat-exchangers, the tubes of which are filled with an appropriate catalyst, are used.
