1.0 IntroductionBiodiesel is defined as mono-alky esters of long -chain fatty acid. It is a fuel that derived from the vegetable oils, animal fats, which is similar to the diesel fuel except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as diesel fuels.…
The purpose of this experiment was to compare biodiesel to other fuels. The ecotoxicity of biodiesel was estimated, along with that of other biofuels through the germination of seeds in the presence of different concentrations of fuels. This resulted in biodiesel having an average of 79.4% germinated seeds in a 10% solution of fuel, compared to other fuels whose percentage of germinated seeds decreased with higher concentrations of fuel. In addition, biodiesel was also synthesized and its heat of combustion was found through the use of calorimetry. The heat capacity for the calorimeter was based on the heat of combustion for ethanol, which was then used to determine the heat of combustion for biodiesel. The average heat of combustion for biodiesel was ∆Hcomb= -13090.83 kJ/mole, as opposed to the theoretical value of -11496.6 kJ/mole, which resulted in a 13.9% difference. Furthermore, taking into consideration the ecotoxicity of biodiesel, its effect on the environment, and fuel efficiency, biodiesel proved to be the more favorable fuel relative to the other fuels tested. The goal of the experiment was to compare and determine the advantages of using biodiesel as a fuel as opposed to other fuels.…

The history of Alternative fuels, or at least the concept of it, has been around since the early days of the automobile. Alternative fuels such as biodiesel, ethanol and methanol, have been produced and used on a small scale for decades. They are now being rediscovered due to the rising cost of oil and the instability of world politics. The discovery of these fuels changed the face of the planet, but since day one people have looked for other fuels that improved over the course of history.…
While energy cannot be created or destroyed, it can be transformed between types. The main sources of energy on Earth are the fossil fuels, including coal, natural gas, and oil, and all of these are nonrenewable resources. Each of these were produced over a period of millions of years under the surface of the Earth, and it is not possible to renew these supplies. The main uses for the energy obtained from the fossil fuels include heating our homes and buildings, generating electricity to run everything from computers to alarm clocks, and providing transportation. In addition to being limited in supply, the burning of coal as an energy source releases sulfur dioxide into the atmosphere, where it causes to the formation of acid rain. As a result of the government's decreasing the amount of sulfur dioxide levels, coal is losing popularity as an energy source. The world's population is growing, and the number of industrialized countries is increasing. Whereas in the past a relatively small predictable group of nations competed for fossil fuels, both competition and demand have significantly increased in recent years. There was a time when electrical systems in homes were only required to power such items as lamps, ovens, and television. When today society and technology place a much greater demand on energy production. Scientists and engineers are engaged in ongoing research to develop alternative energy sources, innovative methods for meeting the world's energy demands to reduce the dependence on traditional, nonrenewable resources, now there have been other ways to produce energy which is very good but each way has a disadvantage.…
Palm Oil is a natural commodity that is obtained from the deforestation of tropical rainforests. Palm Oil is found in many products ranging from Soap and detergent, to cooking oil and edibles such as chocolate; it can also be used as biodiesel for automobiles. Though the uses of Palm Oil ranges for over half of everyday consumer products; the use of the oil carries many detrimental and concerning issues in the Environmental aspect. The article pertaining to the topic of Palm Oil; reveals the negative effects of deforestation.…
Petroleum has been a mainstay of the United State's economy for almost a century. However, oil has now been recognized as a strong catalyst for global warming, it is becoming scarce and therefore, an expensive necessity to America's economy. In the recent years many universities and scientists have looked for alternatives to oil in the form of renewable energies. These renewable energy sources would be cheaper in the long run, more efficient and environmentally clean. America as a whole must look into these new forms of renewable energy to determine if they are a practical alternative to the use of petroleum as an energy source. If we do not try to find a clean and efficient alternative to fossil fuels, I am concerned for the future of our world.…
If the oil processing machinery have heat on oil, then the change of oil viscosity and oil binding. Steam heating effect of the process of speculation, make the billet in high temperature, and weaken the enhanced oil thermal motion of molecules and molecular cohesion, resulting in green oil viscosity and surface tension reduction, weakening the binding of grease and part of the green gel and enhance the mobility of the oil, oil get rid of protein hydrophobic adsorption force and to create the conditions to overcome the flow friction resistance. This change makes the oil mill machinery easier to separate the oil from the oil when the oil is pressed. Chemical changes of oil when oil mill machinery processes oil. In the temperature range used in the process of steaming and frying, it is impossible to make the oil produce profound chemical changes. But because oil is film shaped in the blank surface broad, steaming wok especially when heated contact with oxygen in the air will make the oil oxidation, resulting in oil peroxide value increased. In the oil mill machinery’s cooking process may also produce oxygen acid, make oil acid value increase, also may be due to the binding reaction or some low molecular weight fatty acid is distilled, the oil acid value decreased production of fatty acids and other substances.…

Oil: Oils are esters of glycerol and fatty acid. In other words, oils are tri-glycerol ester of fatty acid. Hence ester of glycerol is known as glycerides and fatty acids both are saturated and unsaturated. Oils are liquid at ordinary temperature. Example: Rice bran oil, Coconut oil, Soybean oil, palm oil. Etc. Fats: Fats are same as oil, i.e. Fats are esters of glycerol and fatty acid, except that fat is solid at ordinary temperature. The melting point above 20°C. Example: Butter, Tallow, Lard etc. Waxes: Waxes are esters of long chain fatty acid. Usually contain 24-28 carbon atoms with long chain primary alcohol containing 16-36 carbon atoms or with alcohol of the steroid group. Waxes are non crystalline. Example: Bees wax, Carnauba wax, opal wax. Etc. Properties of oil: 1. At room temperature oils liquid. 2. Oils contains large proportion of unsaturated fatty acid. 3. Oils are insoluble in water but readily soluble in Hexane, ether, benzene, Carbon tetra chloride, etc. 4. Oils are easily hydrogenated like alkenes. 5. Oils react with Iodine, chlorine in aqueous alcoholic solution to form iodo-chloro derivatives. Terms related Definitions: Iodine value: Iodine value may be defined as the number of gm of Iodine that will add across the Carboncarbon double bond in hundred (100) gm of the fats or oils. Or simply the amount of iodine (in gm) absorbed by 100gm of fat. Significance: Iodine value is a measure of the extent of un saturation in fats or oils. The greater the number of double bond more iodine is required to break this bonds.ie. Iodine value is more. For example Oleic acid has one (C=C) double bond and it iodine value is 85whereas Linoleic acid contain two (C=C) double bond has iodine value is 181. Iodine value of Rica bran oil is 99-108. If Iodine value is below 90 then it is called non drying oil, If iodine value is above 90 and below 140 then it is called semi drying oil and if iodine value is above 140 then it…

The fatty acid compositions of oils added to the chicken rations as an energy source in this experiment was shown in Table (3), and reflection of these oils on fatty acid compositions in all meat chicken was presented in Tables (14, 15, 16 and 17). These compositions of soybean oil and palm oil (PO) were summarized in Table (3) showed that the largest amount in palm oil was oleic acid (39.8 %), followed by palmitic acid content (38.42 %), stearic acid content (5.08 %) and vaccinic acid content (1.92%) compared to soybean oil, which contains the lowest amounts of these fatty acids, which recorded these values (20.69, 9.32, 4.16, and 1.73%, respectively). While, the highest amount showed in…
The Atomic H/C and O/C for heavy oil obtained from different HDO solvent is presented in Fig. 2. Conversion and removal of unstable acid, aldehyde, sugar and water might reduce the O/C ratio. The atomic ratio was calculated by the value of water excluded heavy oil, since H/C ratio could also decrease, despite hydrogenation. Compared with that of bio-oil (0.9), atomic O/C ratio was effectively reduced via HDO reaction (0.2-0.8), H/C ratio reduced 1.0-2.0 (compared with that of bio-oil; 2.1) due to the deoxygenation or dehydration. In case of using polar protic ethanol, O/C ratio steadily decreased from 0.6 to 0.3 with increasing temperaturem while H/C ratio maintained the value of 0.1. However, polar aroptic acetone…
