Claim Text:
1. A method of production of ammonia comprising the steps of: in a first reactor system, extracting oxygen from air using an oxygen selective membrane, thereby producing nitrogen enriched air, and gasifying combustible material in a gasifier, using said oxygen extracted from said air, to produce syngas; in a second reactor system, receiving a hydrogen-depleted syngas from a third reactor system and removing oxygen from said nitrogen enriched air by combustion to produce oxygen-depleted nitrogen enriched air and a carbon dioxide output, with the carbon dioxide output recycled to the gasifier in the first reactor system; and in the third reactor system, separating hydrogen from said syngas directly from said first reactor system to produce hydrogen-depleted syngas and reacting said hydrogen with said oxygen-depleted nitrogen enriched air from said second reactor system to produce ammonia.
