      Brian Westenhaus, over at New Energy and Fuel, has been telling me what a good product corn ethanol is very familiar with raising corn for ethanol, and can see how the process has been improved in recent years. Now it takes hardly any petroleum and chemical inputs from the farmer in order to grow a crop if corn for ethanol. In the future, whether ethanol is competitive with petrol without government assistance will depend on the cost of ethanol production relative to the cost of petroleum-based fuels. High oil prices provide an incentive to develop new technologies for alternative fuel production.

    Bioethanol is the product of fermentation of starch contained in renewable resources, such as corn, wheat, rye and rice. Depending on the technology used for its production, dried distillers decoction may exist in different forms: dried distillers grain (DDG); dried distillers grain with solubles (DDGS) and high-protein dried distillers grains (HPDDG), as well as wet distillers grain (WDG Author: Ewa Pecka-Kiełb, Andrzej Zachwieja, Dorota Miśta, WojciechZawadzki, Anna Zielak-Steciwko.

Callahan.

      The search for alternative fuel sources has led to the development of ethanol, a gasoline substitute, but large-scale production of corn-based ethanol is controversial and it . As a result, there was a boost in demand for ethanol as a substitute for MTBE circa In addition, the Energy Policy Act introduced suffi cient to outpace any feasible domestic grain supply expansion if petroleum suffi cient to outpace any feasible domestic grain supply expansion if petroleum Perspective.” Policy Research.

The essential how-to book on making and using ethanol as an alternative renewable fuel. Dwindling petroleum supplies and growing environmental concerns are significantly impacting the cost of petro-fuel and its infrastructure/5(20).

First, from the consumer's perspective, the current blend of 10 percent ethanol gasoline (E10) offers pros and cons. The BTU efficiency of a gallon of ethanol is about 40 percent less than a. Dwindling petroleum supplies and growing environmental concerns are significantly impacting the cost of petro-fuel and its infrastructure.

The search for alternative fuel sources has led to ethanol, a gasoline substitute that is already in the marketplace as Gasohol and E/5(23). We compare petrol fuel and rice-to-ethanol production using emergy indices.

Rice-to-ethanol reduces green house gas emissions as a substitute for petrol fuel. Rice-to-ethanol production has better sustainability than that of petrol fuel.

Neither petrol fuel nor biofuel production are sustainable in the long term. Bioethanol is not a renewable fuel. Grain ethanol as a petroleum substitute: a perspective Technical Report Alston, T. Present tax exemptions for gasohol are more than sufficient to move ethanol into the gasoline market in.

To better judge ethanol's strengths and weaknesses, we decided to buy a flex-fuel vehicle (FFV) and put E85 to the test. E85 is an ethanol mixture promoted as an alternative to gasoline. All petroleum-based fuels can be replaced by renewable biomass fuels such as bioethanol, bio-diesel, and bio- hydrogen.

Ethanol has long been considered as a suitable alternative to fossil fuels either as a sole fuel in cars with dedicated engines or as an additive in fuel blends with no engine modification requirement when mixed up to 30%.Cited by: Ethanol use in Brazil as a motor fuel has been largely promoted since the two oil shocks of the s, either as a gasoline additive (anhydrous ethanol) or as a gasoline substitute (hydrated ethanol).

Ethanol Benefits and Considerations. Ethanol is a renewable, domestically produced transportation fuel. Whether used in low-level blends, such as E10 (10% ethanol, 90% gasoline), E15 (% to 15% ethanol), or E85 (flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season—ethanol helps reduce emissions.

Like any alternative fuel, the use of ethanol. Recently, there has been interest in using maize for the production of ethanol as a substitute for petroleum-based fuels. It is an important source of carbohydrate, protein, iron, vitamin B, and minerals.

Climate change, however, is a growing concern among corn growers by: 1. On the negative side, General Motors figures it would take billion bushels of corn to create enough ethanol to substitute completely for auto fuel, about 20 times the national production.

Xinglong Energy Inc. in Jiling, with an annual capacity of million gallons of ethanol, is now the biggest fuel ethanol producer, and China expects to achieve a total annual fuel ethanol production capacity of about million gallons in the near future. 9 Initially, these processes targeted the use of grain that was stored so long as a war Cited by:   Simply put, bioethanol is ethanol (alcohol) that is derived exclusively from the fermentation of plant starches.

Though ethanol can be extracted as a byproduct from a chemical reaction with ethylene and other petroleum products, these sources are not considered renewable and therefore disqualify most ethanol from being considered bioethanol. In the USA, for example, ethanol production from maize grain (hereaft er called maize-ethanol) was 15 billion liters inrequiring 36 MMt of grain, or about 13% of the total maize crop.4 Although the Energy Policy Act mandates annual production of 28 billion liters of ethanol by ,Cited by: 1.

Introduction. While US interest in fuel ethanol has grown since the oil crises of the s, its use in gasoline blends accounted for only percent of total fuel use in motor vehicles in Although ethanol (i.e., ethyl alcohol) has the advantage of being derived from domestic resources, its use for fuel has often been criticized as technically, economically and environmentally Cited by: Ethanol is a relatively low-cost alternative fuel that boasts less pollution and more availability compared to unblended gasoline, but there are a number of benefits and drawbacks to this newer form of fuel.

For environmental purposes, ethanol is less harmful than unblended : Larry West. Ethanol is a renewable fuel made from various plant materials collectively known as "biomass."More than 98% of U.S. gasoline contains ethanol, typically E10 (10% ethanol, 90% gasoline), to oxygenate the fuel, which reduces air pollution.

Ethanol is also available as E85 (or flex fuel), which can be used in flexible fuel vehicles, designed to operate on any blend of gasoline and ethanol up to 83%. develop grain-based U.S. ethanol production in the first place. The third point regarding fuel oxygenates is of greater importance than we realize, as MTBE was a product originally being promoted by oil companies as a competitive substitute for grain-based ethanol.

Historically, ethanol is produced in two different ways: as a fermentation product (i.e., bioethanol) or from the petroleum by-product ethylene (i.e., synthetic ethanol).

Synthetic ethanol accounts for less than 10 percent of ethanol production and is used almost exclusively in industrial applications (ORNL, ).

fuel debate). In fact, it has been shown that DDGS can replace corn in livestock diets on a up to a level, depending on the species.such as ethanol, biodiesel, and other liquid and gaseous fuels, could offer an important alternative to petroleum over this timeframe and help reduce atmospheric pollution.

This book looks at recent trends in biofuel production and considers what the future might hold if such alternatives were to displace petroleum in transport. Net Energy Balance (NEB). Despite our use of expansive system boundaries for energy inputs, our analyses show that both corn grain ethanol and soybean biodiesel production result in positive NEBs (i.e., biofuel energy content exceeds fossil fuel energy inputs) (Fig.
