Storage Stability Of Biofuel, Mahendra Varman Munusamy M. Varman
Storage Stability Of Biofuel, Mahendra Varman Munusamy M. Varman
Mahendra Varman Munusamy (M. Varman)
Biofuel is one of the prime candidates to take over the role played by fossil fuel as the main source of energy in the future. Numerous studies have been done on the potential of biofuel to produce similar power output generated by the current petrol and diesel which are depleting without any drawbacks. The objective of this particular study is to investigate 4 of the more established vegetable oil in the energy industry namely jatropha, palm, coconut and canola oil in terms of storage stability of biofuel at room temperature and 80ºC. The biofuels were tested in terms of density, …

The aim of this research was to study biodiesel production from low cost feedstock of waste cooking oil (WCO) using hydrodynamic cavitation apparatus. A two-step processes esterification process and transesterification process using hydrodynamic cavitation for the production of biodiesel from WCO is presented. The first step is acid-catalyzed esterification process for reducing free fatty acid (FFA) content of WCO and followed by base-catalyzed transesterification process for converting WCO to biodiesel as the second step. The result of esterification process with methanol to oil molar ratio of 5 and temperature of 60 oC showed that the initial acid value of WCO …
Degradation Of Automotive Materials In Palm Biodiesel
Degradation Of Automotive Materials In Palm Biodiesel
A.S. Md Abdul Haseeb
As compared to petroleum diesel, biodiesel is more corrosive for automotive materials. Studies on the characterization of corrosion products of fuel exposed automotive materials are scarce. Automotive fuel system and engine components are made from different ferrous and non-ferrous materials. The present study aims to investigate the corrosion products of different types of automotive materials such as copper, brass, aluminum and cast iron upon exposure to diesel and palm biodiesel. Changes in fuel properties due to exposure of different materials were also examined. Degradation of metal surface was characterized by digital camera, SEM/EDS and X-ray diffraction (XRD). Fuel properties were …

Wayne State University Dissertations
Recently, topics including global warming, increased environmental awareness, recycling, and organically produced meat and vegetables have been prevalent in the media and research arenas. The rapidly increasing cost for fossil fuels and the pursuit of environmental conservation has brought about the interest in a renewable and clean burning fuel, specifically biodiesel. Biodiesel, or vegetable oil ester as it was originally referred to, has been improving and progressing since the early 1900's. Fortunately, significant advancement in the understanding of raw vegetable oil as a fuel as well as converting it to ethyl or methyl esters, now known as biodiesel, has been …
