New Zealand has a dwindling supply of natural gas currently used as both a petrochemical feedstock and as a fuel for thermal power stations. However, the country has large reserves of coal, much of it at depths that make it difficult to mine using conventional methods. It is possible to gasify the coal underground and produce a gaseous mixture of hydrogen, carbon dioxide, carbon monoxide and water that can be used as a replacement for natural gas as a feedstock or fuel. This paper describes a design study on the production of urea from underground coal gas in New Zealand.
