Abstract:
An integrated process for the production of ammonia-based fertilizer and liquid hydrocarbon products from fossil fuel derived synthesis gas, said process comprising:contacting said fossil fuel with steam and oxygen-containing gas under partial oxidation conditions sufficient to produce a synthesis gas; passing said synthesis gas comprising nitrogen gas, hydrogen gas and carbon monoxide in a mole ratio of hydrogen to carbon monoxide of between 0.8 to 1 and 5.2 to 1 to a catalytic synthesis gas conversion process under Fischer-Tropsch synthesis conditions for the conversion of the carbon monoxide gas and a portion of the hydrogen gas to fuel products comprising substantially liquid hydrocarbon products and light hydrocarbon gaseous products, wherein said conversion is carried out predominantly in the absence of a water gas shift reactor suitable for the conversion of CO to hydrogen; separating the liquid and gaseous hydrocarbon products from the nitrogen gas and the unreacted portion of the hydrogen gas while recovering the hydrocarbon products; passing the nitrogen gas and the unreacted hydrogen gas as a feedstream to a process for the hydrogenation of the nitrogen whereby ammonia-based fertilizer is produced and recovered.
