Biodiesel production from waste cooking oils
Fuel, 2008Abstract Alkali-catalyzed transesterification of waste cooking oils, collected within Ho Chi Minh City, Vietnam, with methanol was carried out in a laboratory scale reactor. The effects of methanol/waste cooking oils ratio, potassium hydroxide concentration and temperature on the biodiesel conversion were investigated.

Biodiesel from Plant Oil and Waste Cooking Oil
2019Vegetable oil derived from oilseed plantations or crops is the most commonly used feedstock for the production of biodiesel. These oils, primarily including those obtained from rapeseed, sunflower, and palm, are transesterified with methanol in the presence of an alkaline catalyst to reduce their viscosity so that their fuel properties are comparable ...

Production of Bio‐Oil from Waste Cooking Oil by Pyrolysis
Chemical Engineering & Technology, 2021AbstractWaste cooking oil (WCO) is an important feedstock for biofuel production due to its low cost and extensive availability, primarily by transesterification. A more recent approach to take advantage of this feedstock is through pyrolysis. In this study, WCO was collected from a fast food restaurant and then pyrolyzed, employing two different ...

Use of rice husk in waste cooking oil pretreatment
Environmental Technology, 2017Since industrial wastes are increasing, the development of studies to find ways for their use is urgent. Waste cooking oil is an important source for the production of biodiesel, one of the main biofuels in Brazil. However, during cooking, the oil undergoes conditions that change its properties and decrease its quality, such as its acidity value ...

Enzymatic Conversion of Waste Cooking Oils Into Alternative Fuel—Biodiesel
Applied Biochemistry and Biotechnology, 2006Production of biodiesel from pure oils through chemical conversion may not be applicable to waste oils/fats. Therefore, enzymatic conversion using immobilized lipase based on Rhizopus orzyae is considered in this article. This article studies this technological process, focusing on optimization of several process parameters, including the molar ratio ...
