To sum up- butanol probably the most energy and less impacting on environment due to chemical structure- more carbon atoms and bigger hydrocarbon chains but ethanol is the cheapest to produce and can be made from lots of different things making it easier to produce. Also easiest to use as a fuel as it most closely resembles petrol so cars don’t have to be specially designed for it.

    The world will run out of fuel to power our transportation within the next couple generations. The pollutants and greenhouse gases that we our emitting while using the remaining fuel has a negative impact on the earth’s biosphere. Our dependency on foreign oil does not support the economy of the US; while we are supporting unstable countries in the Middle East. The price of gasoline is approaching the point of being unaffordable for many. It is obvious that our reliance on fossil fuels is causing problems that have to be addressed. Biofuels are an important and necessary renewable resource. We must increase the development and production of biofuel in order to reduce and slowly replace gasoline as our primary transportation fuel. Although many people know the potential of biofuels, they have trepidations. There are several significant concepts that are overlooked in the discussion of biofuel production, which could offset the main obstacles and concerns.…

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    In this paper, I will briefly review how ethanol is produced in different parts of the world. I will also review several of the advantages of using ethanol as a renewable source of energy for the transportation sector. Many environmental organizations support the use of ethanol as it burns cleaner than fossil fuels. Ethanol is considered a renewable resource because it is plant based. Additionally, this paper will review several of the common disadvantages of using ethanol as an alternative fuel source for the transportation sector. One of the main issues is the amount of farm land required to produce enough ethanol to significantly offset the amount of fossil fuel currently consumed. This paper will also review current United States policies that support the use of ethanol by American consumers.…

    The main justifications found for this phenomenon are based on global warming and environmental pollution as well the scarcity of petroleum sources around the world. The first biofuels generation use crops as raw material or feedstock, and mostly they are biodiesel and bioethanol, which accounts for over 90% of biofuels that is currently used in the world. In Brazil, Sweden and the United States there are 6 million vehicles that can accept mixtures ethanol/gasoline to 85%. The processing steps are different depending biofuels and raw materials used to obtain the final product. Main steps for bioethanol production, and the technologies used in the first generation are simpler than second generation are, which are based on cellulosic material. In addition, the production costs and investment are lower for the first generation, and it has promoted its popularity (Gonzalez, 2009). However, popularity doesn't necessarily mean benefits, and there are several critiques to biofuels as well as there are praises about this new…

    Abstract: This paper analyzed the basic physical and chemical characteristics of methanol diesel blended fuel. The power and fuel economy performances were studied experimentally when methanol diesel blended fuel was supplied to JiChai 3012 diesel engine, without any changing of the configuration of this machine. The results show that compared to common diesel engine, the diesel engine using 10% and 20% methanol blended fuel show a slightly decrease in power, a less than 5% decrease in the dynamic performance, and an increase in fuel consumption; while the smoke is the reduced by 10% and 20% methanol blended in diesel. Introduction In the modern world, energy and environmental protection have become two major problems which human face. As one kind of energy conversion tool, diesel engine is the one of the most important oil fuel consumer and the exhaustemission of these engines is one of the important reasons causing atmospheric environment pollution. Therefore, how to reduce oil fuel consumption and the environment pollution has become the focus of attention in the modern world science. The methanol resources is rich, especially it can be refined from the coal which is relatively rich in our country. The methanol resource can be self-sufficient in our country, and the methanol industry is also on surplus condition in the worldwide. At present, the methanol gasoline…

    In this experiment, the proponents used mixtures with varied proportions of ethanol and hydrogen peroxide to know which would make a more efficient, clean, and stable combination. Compared to conventional fuels, ethanol contains 36% oxygen thus resulting in more complete combustion. This greatly lowers the formation of carbon monoxide by allowing it to react with oxygen present in ethanol yielding a more eco-friendly gas. Hydrogen peroxide is also added to ethanol since it contributes to the addition of oxygen for complete combustion. The proponents made use of iron stands and iron rings placed on opposite sides of the Tirrill burner. One iron ring held the container of water, where a metal cup with the ethanol-hydrogen peroxide mixture floated. Another iron ring held the beaker with water and a thermometer to measure the water’s temperature. This experiment was tested using five setups with differing ratios of ethanol and hydrogen peroxide. The mixture was indirectly heated to produce a flame. The burning was timed until the ethanol-hydrogen peroxide mixture had completely evaporated. Each ratio was tested three times to assure the precision and accuracy of the results, making a total of fifteen trials. The outcome has led the proponents to conclude that the eight is to two ratio of ethanol to hydrogen peroxide is the best combination to make into fuel.…

    With an increasing awareness in the fight against global warming and greenhouse gas emissions, governments around the world are looking for alternative sources of energy. These include wind, solar and hydro energy sources, known as renewable sources (Able to be regrown). However, one fuel source in particular is currently being used and produced to power both vehicles and electrical generators around the world; biofuels. Biofuels are renewable gas or liquid fuels made from plant matter such as corn, sugar cane and vegetable oils. The two main types of biofuels are known as ethanol and biodiesel; both made from feedstock and are expected to largely reduce greenhouse gas emissions from vehicles. Yet, are biofuels really a viable alternative to solar energy with this fight against global warming increasing?…

    The United States produces a quarter of the world’s total carbon emissions, and American’s per capita emissions are five times the world average. More than 25 percent of manmade emissions of carbon dioxide in the U.S. are from transportation. Light duty vehicles, sport utility vehicles (SUVs), minivans, and other light trucks are prolific carbon dioxide emitters. Using renewable fuels in transportation can help reduce the air pollution associated with burning petroleum. Compared to gasoline, ethanol made from corn is estimated to reduce greenhouse gas emissions by 20-30 percent. Moreover, ethanol from cellulose – made from the stalks, stems and leaves of plants reduce it by about 85 percent or more.…

    From the experimental data and through its analysis, the enthalpy of combustion for the five alcohols were determined; methanol, ethanol, propanol, butanol, and pentanol. As the line of best fit in the graph suggests, the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph, the enthalpy of combustion increases from 140kJ/mol for methanol, which has the smallest molecular mass, to 530kJ/mol for propanol, which has the largest molecular mass.…

    Secondly, biofuels are more environmentally friendly energy sources when compared to conventional energy sources. As biomass-based energy sources are potentially carbon dioxide neutral and recycle the same carbon atoms in the environment (Demirbas, 2008). That is, the carbon content of the biomass comes from the living organisms, once the carbon content is released into the atmosphere, it will be re-absorbed back by living organism through photosynthesis and hence it forms a carbon cycle with no net release of carbon content to the atmosphere. Moreover, biofuels contain much lower sulphur content than that of petrol and diesel such that the use of biofuel neither leads to air pollution nor global warming.…

    Ethanol is a renewable energy source. Assuming a net energy gain, ethanol blended fuels can help limit climate change and reduce greenhouse gases. Unlike fossil fuels, ethanol does not increase atmospheric carbon dioxide levels and it also displaces gasoline consumption. When used as a fuel additive, ethanol has the potential to displace 10% of gasoline consumption and 15% diesel consumption. This gasoline alternative also reduces our reliance on imported oil, which in turn improves the security of our energy supply, as well as some of the harmful effects of petroleum exploration, processing and transportation (Eco Network, 2010).…
