Transesterified vegetable oils (biodiesel) are promising alternative fuel for diesel engines. Used vegetable oils are disposed from restaurants in large quantities. But higher viscosity restricts their direct use in diesel engines. In this study, used cooking oil was dehydrated and then transesterified using an alkaline catalyst. The combustion, performance and emission characteristics of Used ...

There is a false notion of existing available, abundant, and long lasting fuel energy in the Gulf Cooperation Council (GCC) Countries; with continual income return from its exports. This is not true as the sustainability of this income is questionable. Energy problems started to appear, and can be intensified in coming years due to continuous growth of energy demands and consumptions. The deman...

For countries, which produce oil crops, vegetable oil is a potential source of alternative fuel. Over the years there have been many attempts to use various types of vegetable oil directly in diesel engines. These include palm oil, soybean oil, sunflower oil, safflower oil, coconut oil, rapeseed oil, jatropha oil etc. Crude Palm Oil (CPO) is one of the promising renewable bio-fuels. Many resear...

This study considers the feasibility of using highly oxygenated and volatile pyrolysis oils from biomass wastes as sustainable liquid fuels for conversion to a hydrogen-rich syngas using the chemical looping reforming process in a packed bed. Pine oil and palm empty fruit bunches oil‘EFB’were investigated with a Ni/Al2O3 catalyst doubling as oxygen transfer material (OTM). The effect of molar s...

Fatty acids esters were produced from two Nigerian lauric oils, palm kernel oil and coconut oil, by transesterification of the oils with different alcohols using PS30 lipase as a catalyst. In the conversion of palm kernel oil to alkyl esters (biodiesel), ethanol gave the highest conversion of 72%, t-butanol 62%, 1-butanol 42%, n-propanol 42% and iso-propanol 24%, while only 15% methyl ester was...

--------------------------------------------------------ABSTRACT-------------------------------------------------Due to depletion of fossil fuel reserves and increasing cost of the petroleum products are the big troubles of today's world .from past to present, tendency of oil price have increased consecutively. Especially, India has deficient amount of fossil fuel .for this reason, India has to...
