Biodiesel is considered an environmentally friendly alternative because it reduces the amount many toxic substances. Plants such as soybeans require carbon dioxide from the air to produce their stems, roots and leaves. During biodiesel production from soybean oil, carbon dioxide is produced and released in the atmosphere. Carbon dioxide is considered a green house gas (GHG). However, this cycle of GHG emission does not neccersarily contribute to the atmospheric carbon dioxide levels. This is because the next soybean crop will reuse the carbon dioxide emitted for its growth. Another important environmental benefit is that biodiesel reduces particulate matter (PM), hydrocarbon (HC) and carbon monoxide (CO) emissions. These benefits occur because biodiesel contains 11% oxygen by weight. Oxygen allows the fuel to burn better, resulting in fewer emissions from unburned fuel. And lastly, biodiesel fuels do not contain any sulfur and does not have an unpleasant smell when it is emitted from vehicles.
Pure biodiesel showed a significant decline in all of its harmful chemicals except NOx when...
Have you ever wondered how those big heavy construction equipment are able to work day in and day out and able to go through so much work? Well that’s because of their mechanics like me and I’m going to show you what they do day in and day out to keep them going. Thesis Statement: The career of diesel mechanic is challenging, because of everyday is something new and anything can happen. The research will describe the career of diesel mechanic, what is required to become a successful, and the impact this career has on society.
When the problems with gasoline use are considered, the catastrophic environmental effects are the primary concern. Automobile use consumes 70 percent of the United States oil supply and is responsible for one-third of the nation’s carbon emissions (Lovins 173). This results in pollution, global warming, and health problems for the people, plants, and animals. The search for alternative fuel is powered by the increasingly evident environmental problems and long-term health of the planet (Povey 17). Fortunately, reducing emissions globally is predicted to have a positive effect and offset previous harms (Backer).
In Thailand, fruit bundles have to be transported from the plantation to the mills and refineries, which are located in Krabi province. The Thailand government is using palm oil biodiesel to become more sustainable. They are trying to reduce the dependence on import and to improve energy security in the country. After analyzing the life cycle production of methyl ester, it was found that the three major energy consumptions is transportation, fertilizer, and methanol. There should be a reduction in the amount of fertilizer. Biodiesel should be used instead of diesel and fossil fuels, which are often used, for a more environmental friendly way. There should be non-fossil fuels to produce methanol. There should be efficient utilization of co-products, including fibers and shells to improve overall energy output (Pleanjai and
Both gasoline and ethanol have been around since the time of Henry Ford. Gasoline has been the more accessible of all of them. Ethanol and natural gas have been gaining more support over the years and now gasoline contains ten percent ethanol. Propane is mostly used in fleet vehicles. Cars today can run on gasoline with a little ethanol, but too much ethanol can severely damage a vehicle. Only flex fuel vehicles can handle more than ten percent ethanol in a system. Natural gas vehicles are starting to come onto the market. All three fuels have their pros and cons, but the ultimate decision is up to the consumer.
Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapours.
Reading up information and searching for clues (which were not extremely easy), turns out to have broadened my knowledge on Nature and Biomimicry itself and that there are so many people already using wind turbines to harvest the winds energy and know how the world can be saved. Therefore I have come to the conclusion and have seen that my hypothesis has been proven right.
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
Scientists have made great strides in reducing the cost of the biofuel production process by modifying the structure of various plants. In a study published in the journal Science, by genetically modifying plants, the majority of the organic polymer which strengthens cell walls known as lignin can be removed. Doing so avoids the need to soak the plants in hot acid and cuts down the overall cost of the biofuel dramatically. According to the U.S. Department of Energy, biodiesel production reached 1.6 billion gallons in 2013. With a projected transportation fuel use of 214 billion gallons for 2015, biofuels represent approximately a 0.7% fuel
Fuel injection is the introduction of fuel in aninternal combustion engine, most commonlyautomotive engines, by the means of aninjector.
Biodiesel is mainly used as a transportation fuel and as such, their main target demographic would be local individuals over the age of 18 that drive. Moreover, biodiesel is used by larger forms of transportation such as trucks, buses and tractors. With these vehicles generally being work vehicles, it is fair to assume that the target demographic is also working class people whose jobs require them to spend a long time on the road.
Has it ever crossed your mind that our country is facing a huge problem which is fuel shortage? Well, it’s high time you do! Nowadays, any modern country could not develop or survive without source of energy like the most common source of energy is oil. However, our country is depending on oil which is an unrenewable source of energy. Therefore, fuel shortage is a major issue that facing our country which may lead to various negative effect. The consumption of the fuel over the period 2000 till 2008 has increased as the growth production increased by 27% whereas the production of the oil has been decreased by around 22% which leading to a gap which is currently covered through imports. Therefore, the steep increase in the oil consumption turning Egypt from net exporter during the period 1980 to net importer in 2007 which negatively affect all the Egyptian people. Fuel crisis in Egypt is increasing day by day as oil is the foremost source of energy, the consumption of the fuel is increasing due to the population growth and the desire to improve the conditions and standard of living of the people. Also the urbanization and industrialization leads to fuel crisis which may lead to a lot of negative effects toward our country. Therefore, the imports may increase and also the international prices for most of these products. Moreover, petroleum products subsidy leads to undermine the government ability to increase public spending as education and health. Also Egypt government calls on citizens to ration electricity by cutting electricity off. Therefore, There is a lot of organizations were set up to solve this problem as International Atomic Energy Agency (IAEA) , Nuclear Power Plant Authority (NPPA) which took a major rule in ...
fective, cost efficient and environment-friendly process like, simple distillation and study the comparison of different methods present on this field . We aim to reduce the sludge , metals ,dirt and the other volatile matter present in the collected sample of used lubricating oil.
Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
Biofuels produce lesser levels of toxic emissions. The usage of fossil fuels captures heat within the atmosphere of the earth which causes the greenhouse effect, resulting to global warming. Hence biofuels release fewer of these greenhouse gases and so likely contribute less to global warming. Primarily the burning of fossil fuels and clearing of forests have intensified the natural greenhouse effect
