The Production Of Aviation Biofuel From Renewable Feedstock

In the United States biofuel production has grown a lot over the last two decades. In 1995 production was at 500,000 gallons, by 2005 it was 75 million gallons, and by 2006 it was at 224 million gallons [Biofuels ‘13]. The main plant used in the United States biofuel production was the soybean [Biofuels ‘13]. Currently 4 percent of the world’s demand for primary energy comes from biofuels. The more popular and more well-known hydropower only provides 2 percent of the world’s primary energy demand [Maugeri ‘10]. Most modern cars can use up to a 10 percent biofuel mix in their engines without any modifications, though some cars called flex-fuel can use 100 percent biofuel or gasoline [Maugeri ‘10]. One big advantage to using biofuel is that it produces a higher octane rating than gasoline which helps improve engine performance [Maugeri ‘10]. Biofuels currently cost a little more to make compared to gasoline at about a ten to eight ratio respectively [Sanders ‘10]. Hopefully with more farms producing the components for making biofuels hydroponically it can help drive the price down to where it can be competitive with gasoline and one day completely replace it.

Both biodiesel and ethanol are derivatives of biomass that have been processed to create a liquid biofuel. Both types of biofuels have been touted as secure and environmentally safe alternatives to fossil fuels, however the research verifying these claims is extensive but often contradicting. In the following paper, the efficiency and quality of the two types of biofuel will be discussed. The effects of variables such as source materials and production techniques on efficiency and quality will be considered. Due to the limited scope of this paper however, only generalized net analyses of ethanol and biodiesel production will be considered. The production of ethanol requires one of two source materials, cellulose

In this chapter, it was tried to describe a new perspective for the future aviation industry fuel provision. Considering serious constrictions ruled by CAAA, it is of high probability that Avgas, the current conventional aviation fuel, will be forbidden because of air polluting problem it causes and the fact that it contains considerable amounts of lead element which is hazardous. Ethanol, as a green biofuel, has a promising production potential to be introduced as an alternative fuel according to the current aviation market capacity. Advantages and disadvantages of ethanol usage as an aviation alternative was fully described. The necessary airplane engine modification was mentioned to compensate some of ethanol drawbacks along with some case

Our world is finite. That means that there is only a limited amount of air, water, rock, plants and animal material. Earth is like a spaceship with only so many resources. There are no supply ships to drop in and give us a refill of resources. It make us (as global citizens) the caretakers or stewards aboard the spaceship. So, as global citizens we have to take care of our planet and make sure that it has enough resources for its own well being, the other biodiversity living on Earth and even humankind. We must preserve and wisely use what we have. Using renewable resources and energy is one way to do just that. Biofuels are a type of renewable resources. In this report I will be talking about, what are biofuels, what can they do, how biofuels are made, are they available around the world? Should biofuels be used to replace fossil fuels? Why or why not, how do biofuels impact the food supply in 3 rd World Countries, who uses biofuels? Also the cost, pros and cons and environmental benefits or concerns.

In the United States, biodiesel and biofuel production have increased dramatically in recent years due to environmental issues from excessive petroleum usages. The world is now severely depended on oil for many purposes: powering cars, airplanes, farm vehicles, irrigation pumps, etc. It also plays a significant role as raw material for making many products like chemical products, medicines, and fabrics. In the USA, it is becoming more accessible to lessen the dependency on foreign oil. The second highest expense for airlines is the cost of jet fuel. Any increase in oil prices effects huge amount on the airlines costs and maintenances. The global demand for aviation fuel is above 40 billion gallons per year which influenced researchers to explore high quality but low cost feedstocks to produce aviation standard fuel (Oil Price.Com, 2011). Therefore, the key concern of commercial aviation is to find reliable fuel alternatives to cut costs, and reduce volatility of fuel supply and carbon emissions. In recent years, usage of bio jet fuel has got considerable

Biofuels have been used as a source of energy for thousands of years. Wood was the first biofuel to be used as a means to create fires for cooking. Since that time we have discovered numerous ways to use them and the various forms of biofuels that are available for use. Presently our use of biofuels consists largely of additives to gasoline in the form of ethanol. Ethanol is found in almost all of our gasoline products today, in which about 10% is typically mixed as an additive. Some gas stations are now offering nearly pure ethanol fuel known as E85 which is 85% ethanol. This makes ethanol the most common biofuel used worldwide. In response to this, farmers around the world have increased biofuel plant production as a means to meet the new growing demand for it. As time goes on, more modern farming practices are expected to continue to increase the output at which farmers can grow corn and other ethanol producing plants thereby “fueling” the biofuel gas industry. With more resources available to use, ethanol will be an even cheaper additive than it is now.

Biofuels are an essential commodity when it comes to reducing carbon emissions from transportation. The production of biofuels produced from raw materials will ensure the availability of biofuels to maintain the biofuel industry

In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.

To answer the call of this crisis, the world may turn to other energy sources like biofuels, which are a relatively developed, yet innovative alternative to fossil fuels. Biofuel is a cleaner and renewable source of fuel that is able to combat fossil fuel price increases in relation to the limiting supply of fossil fuels with many existing and currently developing biofuel technologies to lower greenhouse gas emission and environmental damage. Biofuel technology derives from organic biomass which may include trees, grasses, plants and aquatic plants. From the photosynthesis of these biomass materials, plants convert carbon dioxide (CO2) and water into carbohydrates (simple sugars) and lignocellulose.

This essay focuses on two renewable energy resources. First of all, biofuel is now accepted as alternative energy in worldwide. The figures continue upward trend in the biofuel production. ‘An annual growth rate of 6.8% from 2006 to 2030 is expected for total biofuels consumption in the transport sector’ (International Energy Agency: 2008 cited in Zhou, et al., 2009:S11). Significant leaders of the biofuel market are Brazil, the United States and the European Union. The results of research indicated that 92% of the world’s ethanol is produced by Brazil and US together, while 90% of the world’s biodiesel manufactured by the EU. In addition, several developing countries in Asia such as Indonesia, Malaysia, Thailand, and the Philippines have an enormous potential for biofuel production. Now these countries are

Aircraft Greenhouse Gas (GHG) emissions – accounting for 12 percent of all US transportation GHGs emissions and 3 percent of total US GHG emissions– endangers public health and welfare (EPA rule and regulation, 40 CFR Parts 87 and 1068). Federal Aviation Administration estimates that nearly 30% of GHGs reduction in aviation sector can be achived with the biojet fuel adoption (FAA, 2012). With the growing concern on the environment, much efforts including reduction plans have been put by governing bodies to limit emission from aviation fuel consumption.

The use of sustainable fuels is still seen as pricey and problematic. Indeed there are still several issues to be addressed and governments together with stakeholders should closely work in order to regulate and ease the supply of those sustainable fuels within the aviation industry, without jeopardising the food sector (Sustainable Aviation Fuel

Biofuels such as Ethanol, Biodiesel, Biogas, Biokerosene, Butanol, Other bio-alcohols are being seen as cleaner forms of energy but ethanol and biodiesel however are increasingly

An alternative fuel for internal combustion (IC) engines is considered as a viable option because of the pollution effect & amount of petroleum products available. As an alternative fuel is biodegradable and renewable fuel, biofuel is the most suited substitute for biodiesel. In developing countries the demand for

With an ever growing population and increasing development around the world, the need for alternative energy sources greatly increases with every passing day. One of the main forms of alternative energy being pushed is biofuels. This is due to their decreased emissions in comparison to more conventional fuels such as diesel and gasoline. I will be covering many aspects in this paper that will highlight the benefits of biofuels, how it started and where it is predicted to be in the future.
