Biofuel from Used Vegetable (Cooking) Oil
Qatar Foundation Annual Research Forum Proceedings, 2011Abstract Everyday people use cooking oil at home and various commercial establishments in the hospitability industry. Particularly hotels and restaurants are generating 0.1 million tons /year of waste cooking oil in India and other countries such as US (0.3–0.4 million tons), EU (0.7–1 million tons), United Kingdom (0.2 million tons), and Canada (0.135

Considerations About Using Vegetable Oils in Lubricants
World Tribology Congress III, Volume 1, 2005New lubricating oils obtained from mixtures of synthetic diesters (di-2-ethylhexyl-adipate (DOA) and di-2-ethylhexyl-sebacate (DOS)) and vegetable oils (sunflower, SFO, soybean, SO and rapeseed oil, RO) are studied. The characteristics of all these mixtures are given together with differential scanning calorimetry (DSC) and thermal gravimetric (TG ...

Esterified cellulose nanofibres from saw dust using vegetable oil
International Journal of Biological Macromolecules, 2020In this work, cellulose nanofibres (CNFs) were extracted from sawdust, which is an underutilized by-product from the wood and timber industry. The extracted CNFs by chemical and mechanical treatments had a web-like structure with diameters ranging between 2 nm and 27 nm and lengths reaching a few microns.

Recycling clays used in Bleaching vegetable oils
Bulletin of Pure & Applied Sciences- Chemistry, 2014The efficiency of recycled clays to bleach oils measured by decrease in absorbance of bleached oils was largest when recycled clays had been calcined at 450°C and leached in boiling mixture of 20% acid strength for 16 hours. The Langmuir constant a varied from 0.4x10−2 to 16 x10−2 and b increased from 4.7x10−2 to 95.38x10−2.

Electrocoagulation of vegetable oil refinery wastewater using aluminum electrodes
Journal of Environmental Management, 2009Electrocoagulation with aluminum electrodes was used to treat the vegetable oil refinery wastewater (VORW) in a batch reactor. The effects of operating parameters such as pH, current density, PAC (poly aluminum chloride) dosage and Na(2)SO(4) dosage on the removal of organics and COD removal efficiency have been investigated. It has been shown that the

Conversion of Vegetable Oil to Biodiesel Using Ultrasonic Irradiation
Chemistry Letters, 2003Abstract The influence of low frequency ultrasounds (28 and 40 kHz) versus mechanical stirring on the transesterification reaction of neat vegetable oil with methanol under base-catalysis was studied and the results are presented. It was found that the optimized variables of 6:1 methanol/oil (mol/mol), 0.5% NaOH (wt/wt), and 40 kHz ...

Comprehensive study of process parameters affecting oil agglomeration using vegetable oils
Fuel, 2013Abstract Spherical agglomeration is a size enlargement process in which the disperse medium is held together in aggregates by liquid bridges of an immiscible agglomerating agent in the dispersion medium in general, an aqueous environment. Extensive studies on the process have shown that the process is affected by a number of process parameters.

Discrimination of vegetable oils using monochromatic light
IMPACT-2013, 2013This paper describes a simple and inexpensive method to characterize and differentiate edible oils including castor, olive, sunflower, mustard and groundnut oil. In this method monochromatic light at wavelength 635nm, 565nm, 470nm and 430nm is passed through the oil sample.

Discrimination of olive oil adulterated with vegetable oils using dielectric spectroscopy
Journal of Food Engineering, 2010Abstract The study focused on application of dielectric spectroscopy to identify the adulteration of olive oil. The dielectric properties of binary mixture of oils were investigated in the frequency range of 101 Hz–1 MHz. A partial least squares (PLS) model was developed and used to verify the concentrations of the adulterant.

Cleaning oiled shores: laboratory experiments testing the potential use of vegetable oil biodiesels
Chemosphere, 2004A series of laboratory experiments were carried out to test the potential of vegetable oil biodiesel for the cleaning of oiled shorelines. In batch experiments, biodiesel was shown to have a considerable capacity to dissolve crude oil, which appears to be dependent on the type of biodiesel used. Pure vegetable oil biodiesels (rapeseed and soybean) were
