Production of biodiesel was involved transesterification process that implicated the reaction between used cooking oil and methanol with aid of KOH. The reaction was carried out at 15 min, 30 min, 60 min, 90 min, and 120 min to evaluate the effect of reaction time on the yield of fatty acid methyl ester (FAME). The highest yield of FAME was obtained at reaction time 60 min. Besides that, the yi...

The prime aim of the current work was to illustrate the components existing in repeatedly used cooking oil and to develop an economical process for the production of fatty acids from low cost feedstock waste. The waste cooking oil was characterized by the occurrence of high molecular weight hydrocarbons and polymerized derivative of esters. Triacontanoic acid methyl ester, 2,3,5,8-Tetramethylde...

The kinetics of Cu(II) transport through a bulk liquid membrane with different membrane materials was investigated in this work. Three types of membrane materials were used: fresh cooking oil, waste cooking oil and kerosene, each of which was mixed with di-2-ethylhexylphosphoric acid (carrier) and tributylphosphate (modifier). Kinetic models derived from the kinetic laws of two consecutive irre...

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 ...

Cooking oils are among the most important dietary components. Some of the influential factors in the combustion pattern of cooking oils include the mode of cooking, knowledge of the diseases caused by cooking oils, and price of cooking oils. This cross-sectional, descriptive-analytical study was conducted in the winter of 2018. The research units were selected via simple random sampling. The sa...

Indonesia is a country with large area of oil palm plantations, so there are many factories for the production cooking oil. Indonesian people use lot because processed food in mostly fried which causes used to be wasted. The purpose this study was determine resistivity on quality can useful field renewable energy and reduce environmental pollution due excessive waste cause damage aquatic ecosys...

Palm oil and soybean oil are the 2 most widely used cooking oils in the world. Palm oil is consumed mainly in developing countries, where morbidity and mortality due to cardiovascular disease (CVD) are on the rise. Although claims about adverse or protective effects of these oils are commonly made, there are no epidemiologic studies assessing the association between these oils and cardiovascula...

Introduction Auto-ignition of cooking oils causes a significant proportion of household fires [1,2]. In addition, the majority of the 50% of all accidental fires in hotels, restaurants and fast food outlets that start in kitchens involve liquid cooking oil or fat as the primary ignition source [3,4]. The potential risk of loss of life and property damage due to cooking oils fires is high. Cooki...
