Introduction to Ammonia Production | AIChE
Ammonia production has become one of the most important industries in the world. Without the crop yield made possible by ammoniabased fertilizers and chemicals, the global population would be at least two to three billion less than it is today (3).Ammonia production has increased steadily since 1946 (), and it is estimated that the annual production of ammonia is worth

Coal can be used as a feedstock in the production of a wide range of chemical fertilizers and other chemical products. The main route to these products was coal gasification to produce syngas. Primary chemicals that are produced directly from the syngas include methanol, hydrogen and carbon monoxide, which are the chemical building blocks from which a whole spectrum of

Anthracite usage was inhibited by the difficulty of igniting it. This was a particular concern in smelting iron using a blast furnace. With the invention of hot blast in 1828, which used waste heat to preheat combustion air, anthracite became a preferred fuel, accounting for 45% of US pig iron production

A future use of biomass for ammonia production opens a window of opportunity to realize a carbonfree WellToWheel chain. There are no engines currently that can run on ammonia, or ammonia as dualfuel, at today''s standards and with the same operating conditions. The work performed are rather at research level, mainly as fuel research on Cooperative Fuel Research (CFR) II engines, and have

· Anthracite is considered the cleanest burning coal available. It produces more heat and less smoke than other coals and is widely used in handfired furnaces. Some residential home heating stove systems still use anthracite, which burns longer than wood. Anthracite has been nicknamed "hard coal," especially by locomotive engineers who used it
