Syngas, or synthesis gas: (from synthetic gas or synthesis gas) can be applied to any of the above gasses, but generally refers to modern industrial processes, such as natural gas reforming, hydrogen production, and processes for synthetic production of methane and other hydrocarbons.
Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, [1] in various ratios. The gas often contains some carbon dioxide and methane . It is principally used for producing ammonia or methanol .
Syngas can be used for heat production and for generation of mechanical and electrical power. Like other gaseous fuels, producer gas gives greater control over power levels when compared to solid fuels, leading to more efficient and cleaner operation. Syngas can also be used for further processing to liquid fuels or chemicals.
The primary difference between the Fischer–Tropsch process and methanol to gasoline processes such as STG+ are the catalysts used, product types and economics. Generally, the Fischer–Tropsch process favors unselective cobalt and iron catalysts, while methanol to gasoline technologies favor molecular size- and shape-selective zeolites. [ 8 ]
The metal oxides in Section E, the small section between the reaction lines 1 and 2, can be used for CLR and CLG, although a significant amount of H 2 O may present in the syngas product. The section for syngas production lies between reaction lines 2 and 3 (Section B).
Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas. [1]
These "acid gases" are removed from the syngas produced by the gasifiers by acid gas removal equipment prior to the syngas being burned in the gas turbine to produce electricity, or prior to its use in fuels synthesis. Nitrogen oxides (NO x) (NO x) refers to nitric oxide (NO) and nitrogen dioxide (NO 2). Coal usually contains between 0.5 and 3 ...
Producer gas is a low energy gas, with perhaps 50% N, while synthesis gas is a high energy gas composed of significant quantity of H2 and CO. Synthesis gas, derived from the water gas reaction is highly endothermic requiring significant energy input, which is more heat than being made in a downdraft gasifier.
