Nitrogenous Chemicals from Carbon Based Materials

Coal and biomass consist carbon-based materials can be used as a source of chemicals. There are four widespread processes allow for making chemicals from coals and biomass: Gasification, liquefaction, direct conversion, and co-production of chemicals and fuels along with electricity. The carbon-based materials are gasified to produce synthesis gas (syngas) with a gasifier which is then converted to parafinic liquid fuels and chemicals by Fischer-Trops synthesis. The humus substances can be recovered from brown coal by alkali extraction. Ammonium sulfate from coal tar by pyrolysis can be converted to ammonia. Nitrogenous biomass materials such as animal and municipal wastes are nitrogen-rich materials. All natural systems include ammonia concentrations below 2 ppm.
