This study aims to prepare a supported catalyst based on zeolite Y doped with NaOMe (sodium methoxide) for the transesterification of waste cooking oil (WCO). The catalytic screening data showed that NaOMe/zeolite is prominent WCO prepared by solvent-free, ball-milling process. We initially tested 5–20% sodium methoxide loading onto and found 20% optimum reaction. reaction required comparativel...

Biodiesel has gained wide acceptance as an alternative to petroleum-derived fuel due its environmentally friendly characteristics such low aromatic and sulfur content, biodegradability exhaust gas emission. Although many types of feedstock could be used produce biodiesel, waste cooking or frying oil (WCO) is a promising multiple-advantage solution. However, the use WCO biodiesel some drawbacks:...

In this study, Aspergillus niger ADM110 fungi was gamma irradiated to produce lipase enzyme and then immobilized onto magnetic barium ferrite nanoparticles (BFN) for biodiesel production. BFN were prepared by the citrate sol-gel auto-combustion method and characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron mic...

Synthesis of biodiesel from various plant oils is realized by the transesterification triglycerides with methanol or a reaction usually defined as methanolysis. The usage low-quality oils, such waste cooking oil (WCO), followed undesirable side reactions result increased content free fatty acids (FFA), and water. presence FFA in WCO requires pretreatment stage before subjecting it to In present...

One of the most dangerous cancers in humans is Melanoma. However, early detection of melanoma can help us to cure it completely. This paper presents a new efficient method to detect malignancy in melanoma via images. At first, the extra scales are eliminated by using edge detection and smoothing. Afterwards, the proposed method can be utilized to segment the cancer images. Finally, the extra in...

New de novo sources of omega 3 (n-3) long chain polyunsaturated fatty acids (LC-PUFA) are required as alternatives to fish oil in aquafeeds in order to maintain adequate levels of the beneficial fatty acids, eicosapentaenoic and docosahexaenoic (EPA and DHA, respectively). The present study investigated the use of an EPA+DHA oil derived from transgenic Camelina sativa in Atlantic salmon (Salmo ...

This work explores the feasibility of using waste cooking oils (WCO) as eco-lubricants. Five WCO from different food facilities were studied. Three them fractionated into both lighter and heavier fractions by molecular distillation. A comprehensive chemical characterization (fatty acids distribution, polar compounds acidity) was carried out on all WCOs their fractions, which led to set relation...

The depletion of conventional fuels and increase in global warming due to burning forces scientists develop sustainable alternative which are renewable suggested biodiesel as an immediate substitute for the diesel fuel. potential waste cooking oil is increasing recent years people avoiding usage (WCO). In this work, was produced from WCO used partial studied impact titanium oxide (TiO 2 ) nanop...

Various proportions of bentonite clay performing as co-catalysts were evaluated for the production biodiesel from waste cooking oil (WCO). The results showed that use a heterogeneous co-catalyst could significantly increase yield by approximately 50% control. improved properties produced including acid number, free fatty acids (FFA), relative density, kinematic viscosity and flash poi...
