Hydrocracking of used cooking oil for biofuels production

Bioresource Technology, 2009
Hydrocracking of used cooking oil is studied as a potential process for biofuels production. In this work several parameters are considered for evaluating the effectiveness of this technology, including hydrocracking temperature, liquid hourly space velocity (LHSV) and days on stream (DOS).

Biodiesel production from mixtures of canola oil and used cooking oil

Chemical Engineering Journal, 2008
Abstract Used cooking oil (UCO) was mixed with canola oil at various ratios in order to make use of used cooking oil for production of biodiesel and also lower the cost of biodiesel production. Methyl and ethyl esters were prepared by means of KOH-catalyzed transesterification from the mixtures of both the oils.

Biodiesel production from used cooking oil: A review

Renewable and Sustainable Energy Reviews, 2013
Abstract This paper aims at the assessment of the methods of production of biodiesel from different types of used cooking oil. Researches into the productive chain of this type of biofuel were performed in Brazil while several scientific studies approaching processes of pretreatment and transesterification of waste cooking oil were analyzed with ...

Physicochemical Properties of Refined Palm Cooking Oil and Used Palm Cooking Oil

Materials Today: Proceedings, 2019
Abstract In public restaurants, food frying is conducted in the same oil and recycled for the same usage for several days. However, during household frying, the cooking oil is changed after several usage. Obviously, the conditions of the cooking oil changed depend on frying styles and the types of material fried.

Diesel particulate emissions from used cooking oil biodiesel

Bioresource Technology, 2008
Two different biodiesel fuels, obtained from waste cooking oils with different previous uses, were tested in a DI diesel commercial engine either pure or in 30% and 70% v/v blends with a reference diesel fuel. Tests were performed under a set of engine operating conditions corresponding to typical road conditions. Although the engine efficiency was not

Purification of biodiesel from used cooking oils

Applied Energy, 2011
Abstract In Europe, methyl esters cannot be classified as biodiesel until the EN 14214 Standard specifications are fulfilled. The aim of this paper is to examine the efficiency of removing several impurities in biodiesel from used cooking oils by means of three basic operations under conditions that have been kept as close to commercial operating ...

Use of rice husk in waste cooking oil pretreatment

Environmental Technology, 2017
Since 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 ...

Production of Biodiesel from Cooking Oil Using CaO Catalyst

Advanced Materials Research, 2015
Transesterification method was carried out in biodiesel production from cooking oil (CO). Calcium oxide (CaO) was selected as the best catalyst. This study investigated the effects of percentage conversion of oil to biodiesel from methanol to oil molar ratio and catalyst amount.
