The document describes a chemical process involving urea, ammonium nitrate, water, and high temperature and pressure conditions. Urea is produced through a neutralization reaction of ammonium nitrate at 200 degrees Celsius and 200 atmospheres of pressure. The urea is then dissolved in water and undergoes oxidation.
