AMMONIA AND UREA PRODUCTION - PDF
The carbon monoxide is converted to carbon dioxide for use in urea production, and the carbon dioxide removed: CO + H 2 O! CO 2 + H 2 The remaining traces of CO and CO 2 are converted to methane and then the gases cooled until the water becomes liquid and can be easily removed. The nitrogen and hydrogen are then reacted at high temperature and pressure using an iron catalyst to form ammonia.

Urea production is not carbon sequestration – AMMONIA .
Urea production is not carbon sequestration by Trevor Brown. April 22, 2016. To make urea, fertilizer producers combine ammonia with carbon dioxide (CO2), but when farmers apply that urea to the soil, an equal amount of CO2 is emitted to the atmosphere. No CO2 is permanently stored or sequestered through the production of urea. This is .
