Titel
Fertilizer production from coal and coal bed methane with minimized carbon emissions
Abstract
The production of nitrogen fertilizers is responsible for a significant part of the carbon dioxide emissions especially if the production is based mainly on coal, e.g. China and South Africa. A life cycle analysis for the production of urea and ammonium nitrate is performed and the advantages and disadvantages of both fertilizers for crop growth are discussed. For both cases, the option of carbon dioxide sequestration into deep coal beds for enhanced coal bed methane recovery is considered. It is shown, that CO2 emission to the atmosphere can be reduced by 93 % in the case of AN manufacture and storing the CO2 separated during synthesis gas production.
