Abstract 1. IN A PROCESS FOR SYNTHESIZING AMMONIA AT HIGH PRESSURE FROM A FEED GAS STREAM CONTAINING HYDROGEN AND NITROGEN, THE STEPS COMPRISING PASSING SAID FEED GAS STREAM IN HEAT EXCHANGE RELATIONSHIP WITH A PARTIALLY SYNTHESIZED GAS HAVING A TEMPERATURE FROM ABOUT 800 TO 1100*F. TO INCREASE THE TEMPERATURE OF SAID FEED GAS STREAM TO ABOUT 650-800*F. AND REDUCE THE TEMPERATURE OF SAID PARTIALLY SYNTHESIZED GAS, PASSING SAID HEAT EXCHANGED FEED GAS STREAM DIRECTLY FROM SAID HEAT EXCHANGE STEP TO A SYNTHESIS CONVERTER AND SUBJECTING THE SAME TO SYNTHESIS CONDITIONS TO PRODUCE PARTIALLY SYNTHESIZED GAS, AND THEREAFTER PASSING SAID HEAT EXCHANGED PARTIALLY SYNTHESIZED GAS DIRECTLY FROM SAID HEAT EXCHANGER TO A SYNTHESIS CONVERTER AND SUBJECTING SAID PARTIALLY SYNTHESIZED GAS TO FURTHER SYNTHESIS THEREIN.
