Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.
Biodiesel sample. Blends of biodiesel and conventional hydrocarbon-based diesel are most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system known as the "B" factor to state the amount of biodiesel in any fuel mix: [8] 100% biodiesel is referred to as B100; 20% biodiesel, 80% petrodiesel is ...
For the purposes of the definition alternative fuel in subsection 2(1) of the Act, the following, when used as the sole source of direct propulsion energy of a motor vehicle, are prescribed to be alternative fuels: (a) ethanol; (b) methanol; (c) propane gas; (d) natural gas; (e) hydrogen; (f) electricity;
Biofusion assembly of two BioBrick parts.The schematic diagram shows the 6 base pair scar site made due to the deletion and insertion of nucleotide in the XbaI and SpeI sites. Pam Silver's lab created the Silver assembly standard to overcome the issue surrounding the formation of fusion protein.
The two most common types of biofuel are bioethanol and biodiesel. Brazil is the largest producer of bioethanol, while the EU is the largest producer of biodiesel. The energy content in the global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. [17]
Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel.In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from a reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel.
The most liberal definition accepts all of the above input materials and allows for any form of output fuel: liquid, gas, or "clean" solid. This is the approach of petrochemist James G. Speight; he also mentions that in the context of substitutes for petroleum-based fuels it has even wider meaning. [11]
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
