pdf for production of biodiesel from neem oil its performance

Abstract

In the current energy scene of fossil fuel, renewable energy sources such as biodiesel, bioethanol, biomethane, and biomass from wastes or hydrogen have become the subjects of great interest. These fuels contribute to the reduction of dependence on fossil fuels. In addition, energy sources such as these could partially replace the use of those fuels which are responsible for environmental pollution and may be scarce in the future. For these reasons they are known as “alternative fuels”. Vegetable oil cannot be directly used in the diesel engine for its high viscosity, high density, high flash point and lower calorific value. So it needs to be converted into biodiesel to make it consistent with fuel properties of diesel. Biodiesel production is a valuable process which needs a continued study and optimization process. The present study was intended to consider aspects related to the production of biodiesel from Neem oil and investigating its fuel properties. The seeds of Neem contain 30-40% oil. This report deals with biodiesel obtained from Neem oil which are mono alkyl esters produced using ‘Transesterification’ process. The optimum conditions to achieve maximum yield of biodiesel were investigated at different temperatures and with different molar ratio of Neem oil and methanol. The most expected result including layer of glycerin and soap has been investigated at 3:1 molar ratio of methanol and Neem oil at 55 to 61 °C temperature ranges. It was apparent that the fuel properties of biodiesel including density, kinematic viscosity and calorific value lie within the standards biodiesel properties especially (ASTM 6751-02) recommended standard of kinematic viscosity lies between 1.90 to 6.0 centistokes. Biodiesel can make a major contribution in the future if it meets the few percent of petroleum and it can provide improved fuel properties lower emission of unburned hydrocarbons, carbon monoxide but higher level of oxides of nitrogen.

Neem Oil as a Biofuel

Neem oil is a vegetable oil pressed from fruits and seeds of neem, an evergreen tree which is widespread to the Indian Subcontinent and in many tropical areas.

Characteristics:

Neem oil is Light to Dark Brown in color, Bitter in taste and has a strong odor.
It comprises of Triglyceride and Triterpenoid compounds.
Neem Oil is Hydrophobic in nature and in order to emulsify it in water for application purpose.

Neem Oil contains steroids (Campesterol, beta-sitosterol, stigmasterol) and a plethora of Triterpenoid


Method of Extraction

The method used such as pressing (expelling) or solvent extraction is likely to affect the composition of oil as the methods that are used are unlikely to remove the same mix of components in the same proportion. Neem Oil can be obtained through pressing (crushing) of the seed kernel through cold pressure or through a process incorporating temperature controls.

Neem Oil can also be obtained from solvent extraction of the neem seed, fruit, oilcake or kernel. A large industry in India extracts the oil remaining in the seed cake using hexane. This solvent-extracted oil is of a lower quality as compared to the cold pressed oil and is mostly used for soap manufacturing. Neem cake is a by-product obtained in the solvent extraction process for neem oil.
