Biodiesel fuel is made from natural and renewable resources. It can be manufactured from algae‚ vegetable oils‚ animal fats‚ or recycled restaurant greases. Fresh soybean oil is most commonly used. In general they are made from fats and oils‚ which are hydrocarbons. These hydrocarbons are filtered and mixed with an alcohol‚ such as methanol‚ and a catalyst‚ resulting in a chemical reaction whose major products are biodiesel fuel and glycerol. Biodiesel fuel is light to dark yellow in color as

changes to existing systems. Secondly‚ biofuels are environmentally superior fuels. Thirdly‚ there is need to meet the global environmental concern about climate change‚ ensure energy security‚ reduce imports‚ generate employment for the poor and achieve a number of other objectives. Of the bio-energy alternatives‚ one exciting trend is biodiesel – the manufacture and use of diesel-like substitute from plant and animal fats. The rationale of taking up a programme for the production of bio-diesel

Coco Methyl Ester (CME)/ Biodiesel You may be perhaps heard several rumors regarding Coco methyl ester (CME) or also recognized as Biodiesel. Biodiesel is a substance that can boost and make your automobile run better. This substance comes from coconut oil and goes through into a procedure called as esterification. It is not come from a typical crude oil‚ which is normally being imported from different oil-producing nations. After extorting the coconut oil from copra or dried coconut meat

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

BIODIESEL INCORPORATED Summary Josh‚ Long and Hammond came up with a business idea of manufacturing and distributing biodiesel. The major generation sources‚ petroleum‚ coal‚ natural gas aand nuclear are non renewable resources and have detrimental effects on the environment. The petrochemical fuel industry manifest itself in the form of oil fields and reserves‚ pipelines‚ transport ships‚ and fuelling stations. The whole idea behind the biodiesel was that it can be produced again and it did not

IMPORTANCE OF BIODIESEL The world’s accessible oil reservoirs are gradually depleting due to a burgeoning demand of fossil fuels. Owing to the enormous dependency of transport vehicles running on gasoline engines‚ the development of bio-gasoline may well reduce the dependence of the fuel market on fossil fuels. Biofuel development has gained the attention of researchers in recent years owing to the rate of depletion of fossil fuels. Several processes are currently employed in the conventional

Theory: In the production of biodiesel from cooking oils (glycerides) and methanol are combined with sodium hydroxide as a catalyst. This causes the oils to break apart and reaction of the oils with the methanol. As seen in Figure 1‚ this produces biodiesel (in the form of esters) and glycerol. Figure 1: The production of biodiesel (esters) from glyceride (cooking oils) and an alcohol (methanol). In combustion‚ a substance can be completely or incompletely combusted. In complete combustion‚
