Second generation biofuels - Wikipedia, the free encyclopedia - Second generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of biomass.
Biomass is a wide-ranging term meaning any source of organic carbon that is renewed rapidly as part of the carbon cycle. Biomass is derived from plant materials but can also include animal materials. Biofuel - Wikipedia, the free encyclopedia - (Build 201004010646. A biofuel is a fuel that contains energy from geologically recent carbon fixation.
These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form.
Biodiesel - Wikipedia, the free encyclopedia - (Build 2010040106. Bus run by biodiesel Space-filling model of methyl linoleate, or linoleic acid methyl ester, a common methyl ester produced from soybean or canola oil and methanol Space-filling model of ethyl stearate, or stearic acid ethyl ester, an ethyl ester produced from soybean or canola oil and ethanol.
Alcohol fuel - Wikipedia, the free encyclopedia - (Build 2010040. A dish of ethanol aflame Throughout history, alcohol has been used as a fuel.
The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines. The general chemical formula for alcohol fuel is CnH2n+1OH.
Biogas - Wikipedia, the free encyclopedia - (Build 2010040106463. Pipes carrying biogas (foreground), natural gas and condensate Biogas typically refers to a mixture of gases produced by the breakdown of organic matter in the absence of oxygen.
Biogas can be produced from regionally available raw materials such as recycled waste. Biodiesel 101 - (Build 20100401064631)
