Abstract
Systems and methods for producing syngas and ammonia are provided. The method can include reforming a hydrocarbon in a first reaction zone in the presence of one or more first catalysts and steam at conditions sufficient to produce an effluent comprising a portion of the hydrocarbon, carbon monoxide, carbon dioxide, and hydrogen. The effluent can be reformed in a second reaction zone in the presence of one or more second catalysts and nitrogen at conditions sufficient to produce a syngas comprising methane, hydrogen, nitrogen, carbon monoxide, and carbon dioxide, or any combination thereof. At least a portion of the nitrogen and hydrogen in the syngas can be converted to ammonia to produce an ammonia effluent. The ammonia effluent can be separated to produce an ammonia product and a purge gas comprising nitrogen. At least a portion of the purge gas can be recycled to the hydrocarbon, the effluent, or a combination thereof.
