Preparation of biodiesel from waste cooking

The reaction time and different molar ratio of oil to sodium hydroxide solution through saponification process were optimized. The top layer is usually yellow or light brown color methyl ester. As with the oil, the water content of the alcohol affects the extent of conversion enough to prevent the separation of glycerol from the reaction mixture.

A sudden increase in oil viscosity is attributed to oxidation and polymerization of unsaturated fuel parts entering into oil through dilution.

The by product of biodiesel such as glycerol which can be used in so Related posts: This is the main reason why almost all vehicles prefer using biofuel for combustion purpose.

Biodiesel is known for its reduced oxidation stability. In this process, 0. It is widely used today to produce the oxygenate MTBE added to cleaner burning gasoline. Technical feasibility assessment of oleic sunflower methyl ester utilization in diesel bus engines.

Saponification For saponification process required amount of WCO was taken in a three necked flask and mixed with different stoichiometric amount of aqueous sodium hydroxide solution. The use of non-edible oil for biodiesel production compared with edible oil is very significant in developing countries because of the tremendous demand of edible oil as food and they are far too expensive to be used as fuel at present [ 56 ].

After saponification and acidification FFA was produced. This feedstock could instead enter the animal or human food chain, and as the global population has risen their use in producing bio-fuels has been criticized for diverting food away from the human food chain, leading to food shortages and price rises.

In this sense, methods that permit minimizing the costs of the raw material are of special interest. Volume will either be measured or calculated or both. Lubricity The lubricity of the fuel depends on the crude source, the refining process to reduce sulphuric content and type of additives used.

There are concerns that biodiesel feedstock may compete with food supply in the long-term. Ganvir, professor in petrochemical department in Laxminarayan Institute of Technology, Nagpur for his valuable guidance, practical suggestion and encouragement to bring about this completion of this project.

Density Biodiesel is slightly heavier than conventional diesel fuel specific gravity0. In the present study biodiesel was prepared from WCO by three-step method to increase the reaction yield and minimize the methanol molar ratio.

In the project we focused on the production of biodiesel from waste cooking oil. Distillation point The distillation point characteristics of the biodiesel are quite different from that of diesel.

In Bangladesh the potentiality of producing oil source is investigated and it is found that the production potential is not too high. The use of non-edible oil for biodiesel production compared with edible oil is very significant in developing countries because of the tremendous demand of edible oil as food and they are far too expensive to be used as fuel at present [ 56 ].

The use of waste frying oil, instead of virgin oil, to produce biodiesel is an effective way to reduce the raw material cost because waste frying oil is estimated to be about half the price of virgin oil [ 8 ].Apr 12,  · Looking for a guide on How To Make Biodiesel Using A Used Cooking Oil?

This suitable short video explains precisely how it's done, and will help you get good at drive green. You can also make biodiesel from waste cooking oil, but that is a little more involved, so let's start with the basics.

The objective of this research was to prepare biodiesel from waste cooking oil and to study the performance characteristics in a diesel engine without any modification.

In this work, biodiesel was prepared from waste cooking oil collected from a local restaurant in Multan, Pakistan.
