10 Disadvantages of Biofuels - HowStuffWorks

Biofuel production using food crops such as corn, soybeans and sorghum has the potential to alter drastically the world's access to affordable food. The simple supply-and-demand economics of biofuels -- increase demand for corn, for example, and corn becomes more expensive -- can pose a threat to some regions' food security, or the access to affordable nutritious food for the …

Diesel Fuel - an overview | ScienceDirect Topics

Diesel fuels are complex compounds of hydrocarbon molecules, which generally boil within the temperature range of 150 C to 380 C [1, 33].They are normally blended from several refinery streams, mostly coming from the primary distillation unit. However, in a conversion refinery, components from other units, like cracking processes, are often used to increase diesel fuel …

Difference Between Kerosene and Diesel | Difference Between

Difference Between Kerosene and Diesel Kerosene and diesel are part of crude oil’s byproducts following a refining process. Crude oil, also called petroleum, is extracted from the ground and then taken to the refinery stage where several molecular constituents will be derived. Among others, lies the diesel and kerosene which are often confused by some people.

Ethanol - Wikipedia

Ethanol - Wikipedia

Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic chemical compound.It is a simple alcohol with the chemical formula C 2 H 6 O. Its formula can be also written as CH 3 − CH 2 − OH or C 2 H 5 OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH.Ethanol is a volatile, flammable, colorless liquid with a ...

From there distillation occurs. This recovers 95% ethanol which goes through a molecular sieve to become 100% ethanol and goes into denatured ethanol storage with gasoline. From distillation whole stillage is also recovered. This goes into separation/centrifugation and yields thin stillage and WDG.

Downstream Processing - an overview | ScienceDirect Topics

Since azeotropic distillation is complicated and expensive, molecular sieving methods have been implemented recently in large-scale ethanol purification. The molecular sieves let the smaller water molecules (0.28 nm) pass through while retaining dehydrated ethanol (0.44 nm) (Chopade et al., 2015). It is possible to regenerate molecular sieves ...
