Ethanol fuel - Wikipedia
Ethanol fuel is fuel containing ethyl alcohol, the same type of alcohol as found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. Several common ethanol fuel mixtures are in use around the world.
Biofuel Basics - Department of Energy
Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.
生物燃料乙醇 - 百度百科
生物燃料乙醇是一种“生长出来的绿色能源”，可以用含淀粉（玉米、小麦、薯类等）、纤维素（秸秆、林木等）或糖质（甘蔗、糖蜜等）等原料经发酵蒸馏制成，除大量应用于化工、医疗、制酒业外，还能作为能源工业的基础原料-燃料（燃料低热值为26900kJ/kg）。 燃料乙醇是通过对乙醇进一步脱水，使其含量达99.6%以上，再加上适量变性剂而制成的。 [1] 生产燃料乙醇的生物质原料从工艺角度来看，生物质中只要含有可发酵性糖（如 葡萄糖 、麦芽糖、 果糖 和蔗糖等）或可 …
Ethanol explained - U.S. Energy Information Administration (EIA)
In the United States, nearly all fuel ethanol is produced from corn kernel starch, which is considered a conventional biofuel under the U.S. Renewable Fuel Standard Program (RFS). Ethanol has other potential sources aside from fermentating grain starch and sugars.
Biofuels explained Biofuels and the environment - U.S. Energy ...
2022年4月13日 · Pure ethanol and biodiesel are nontoxic and biodegradable, and if spilled, they break down into harmless substances. However, fuel ethanol contains denaturants to make fuel ethanol undrinkable. Similar to petroleum fuels, biofuels are flammable (especially ethanol) and must be transported carefully.
Biofuels, from ethanol to biodiesel, facts and information
2019年7月15日 · Much of the gasoline in the United States contains one of the most common biofuels: ethanol. Made by fermenting the sugars from plants such as corn or sugarcane, ethanol contains oxygen that...
Biofuels - Energy System - IEA
Biofuels play a particularly important role in decarbonising transport by providing a low-carbon solution for hard-to-abate sectors such as trucking, shipping and aviation. They can often be used in existing engines with little to no modification.
Bioethanol – European Biomass Industry Association
Bioethanol has been extensively tested in light duty flexible fuel vehicles (FFV) as E85G. ETBE is also used in blends of 10-15 % with gasoline to enhance its octane rating and reduce emissions. Blends of gasoline with up to 22% ethanol (E22G) can be used in spark ignition engines without any material or operating problems.
Ethanol vs. Petroleum-Based Fuel Carbon Emissions
2022年6月23日 · Biofuels have been proven to emit significantly lower greenhouse gas (GHG) emissions than petroleum-based fuels, and recent scientific studies indicate that net-zero emission biofuels are not only possible, but achievable. Corn ethanol and other biofuels
What is bioethanol and what is it used for? | Repsol
Biofuels or e-fuels are liquid fuels that come from renewable raw materials and one of their main assets is that they have zero or low CO 2 emissions during their production and final use. Among them, we can mention biodiesel, biogas, or bioalcohols such as bioethanol. What is bioethanol and how is it obtained?
