PROCESS FOR PRODUCING AMMONIA AND UREA

摘要

Disclosed is a process for the production of ammonia comprising a step wherein synthesis gas is formed by catalytic partial oxidation. Also disclosed is a process of producing urea, wherein ammonia is formed in a process involving a step of catalytic partial oxidation, and carbon dioxide formed in the same process is reacted with said ammonia so as to form urea.

主权项

1. A process for the production of ammonia, comprising the steps of
(a) providing a hydrocarbon material; (b) subjecting the hydrocarbon material to catalytic partial oxidation (CPO) in a CPO reactor so as to produce a synthesis gas comprising carbon monoxide, hydrogen and carbon dioxide; (c) subjecting the synthesis gas to a water gas shift reaction in a hydro-treating reactor so as to react carbon monoxide with water to form a gas mixture comprising hydrogen and carbon dioxide. (d) separating hydrogen from the mixture of (c); (e) reacting the hydrogen with nitrogen under ammonia-forming conditions so as to produce ammonia, wherein the catalytic partial oxidation of (a) is a short contact time catalytic partial oxidation, conducted under a space velocity of 100,000 to 250,000 hr−1.
