Abstract:
A process comprising:(a) partially oxidizing solid or liquid hydrocarbon materials, or a mixture thereof, by reacting said materials with an oxygen-rich gas in the presence of a temperature moderator, thereby generating a first synthesis gas mixture comprising carbon monoxide, hydrogen and carbon dioxide; (b) partially oxidizing a natural gas feed by reacting said natural gas with an oxygen-rich gas, thereby generating a second synthesis gas mixture comprising carbon monoxide, hydrogen and carbon dioxide; (c) combining the first synthesis gas mixture with the second synthesis gas mixture, forming a combined synthesis gas mixture comprising carbon monoxide, hydrogen and carbon dioxide; (d) converting a portion of the carbon monoxide in the combined synthesis gas mixture into hydrogen and carbon dioxide; (e) removing the carbon dioxide from the combined synthesis gas mixture, leaving a hydrogen stream; (f) reacting the hydrogen stream with nitrogen to form ammonia; and (g) reacting a portion of the ammonia with a portion of the carbon dioxide to form urea.
