The economic feasibilities of four continuous processes to produce biodiesel, including both alkali- and acid-catalyzed processes, using waste cooking oil and the 'standard' process using virgin vegetable oil as the raw material, were assessed. Although the alkali-catalyzed process using virgin vegetable oil had the lowest fixed capital cost, the acid-catalyzed process using waste cooking oil w...

Growing concern regarding energy resources and the environment has increased interest in the study of alternative sources of energy. To meet increasing energy requirements, there has been growing interest in alternative fuels like biodiesel to provide a suitable diesel oil substitute for internal combustion engines. Biodiesels offer a very promising alternative to diesel oil since they are rene...

development of oil cooking for biodiesel environment capability

A solar cooking system using vacuum-tube collectors with heat pipes containing a refrigerant as working fluid has been fabricated, and its performance has been analysed experimentally. The experiments were conducted during clear days in July and August of 2002 in Elazı g, Turkey under similar meteorological conditions for three refrigerants and water. Detailed temperature distributions and thei...

In this study, we combined different physico-chemical methods to show the effect of overheating on the quality of golden fry cooking oil. Those methods include spectroscopic methods such us 1H-NMR, 13C-NMR and FTIR. Results showed that both overheating and excessive reuse of golden fry cooking oil seriously affected its quality by increasing its density, viscosity and different indexes like ref...

This paper presents performance study of Peugeot MM540 diesel engine using biodiesel prepared from used cooking oil. Transesterification process is followed to produce bio diesel and is blended with diesel in different proportion of 22:78 and 24:76 by volume and named as blend B22 and B24 respectively. Engine was run at different loads (0, 15, 30, 35, and 40kg) with constant speed of 1000rpm se...

Biodiesel is a non-petroleum fuel designed to run in a diesel engine. It can be made from a variety of different feedstocks, including virgin vegetable oil, waste cooking oil, and animal fats. The aim of this research was to compare and contrast biodiesel made from fish oil to other more traditional sources. In this paper I examined traditional biodiesel feedstocks available in coastal Alaska. ...

The present investigation was conducted to study the effect of processing (soaking and germination) and cooking methods (ordinary cooking and autoclaving) on the chemical composition, sugars and phytic of two varieties soybean seeds, Giza, 21 and Giza, 35. The processing and cooking methods caused increase in both protein and crude fiber contents. Meanwhile, crude oil and carbohydrates contents...
