Glycerol is a good alternative source for butanol production. While glucose sources are valuable and limited, glycerol is abundant and has a low market price because it is a waste product of biodiesel production. Butanol production from glycerol is economically viable using metabolic pathways that exist in the bacterium Clostridium pasteurianum ...
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).
Butanol is an alcohol which can be used as a fuel in most gasoline internal combustion engines without engine modification. It is typically a product of the fermentation of biomass by the bacterium Clostridium acetobutylicum (also known as the Weizmann organism).
Butanol combustion: C 4 H 9 OH + 6O 2 → 4CO 2 + 5H 2 O + heat Propanol combustion: 2C 3 H 7 OH + 9O 2 → 6 CO 2 + 8H 2 O + heat The 3-carbon alcohol, propanol (C 3 H 7 OH), is not often used as a direct fuel source for petrol engines (unlike ethanol, methanol and butanol), with most being directed into use as a solvent. However, it is used ...
The main products of syngas fermentation include ethanol, butanol, acetic acid, butyric acid, and methane. [2] Certain industrial processes, such as petroleum refining, steel milling, and methods for producing carbon black, coke, ammonia, and methanol, discharge enormous amounts of waste gases containing mainly CO and H
The long roots of switchgrass suck up excess nitrogen while the plant grows. There are evolving markets for using harvested switchgrass in erosion-control silt socks and poultry bedding.
The largest use of 1-butanol is as an industrial intermediate, particularly for the manufacture of butyl acetate (itself an artificial flavorant and industrial solvent). It is a petrochemical derived from propylene. Estimated production figures for 1997 are: United States 784,000 tonnes; Western Europe 575,000 tonnes; Japan 225,000 tonnes. [8]
He wants industry – real estate, homebuilding, and remodelers – “to know that we have a space that we need your help to fill,” he told USA TODAY.
