How can you reduce vegetable oil viscosity?
There are a number of ways to reduce vegetable oil's viscosity. These methods include; Transestrification, Pyrolysis, Micro Emulsion, blending and thermal depolymerization. One of the most common methods used to reduce oil viscosity in the Biodiesel industry is called transesterification. This is not a new process and by all accounts it was conducted as early as 1853, by the two chemists, E. Duffy and J. Patrick. One of the first uses of transesterified vegetable oil was powering heavy duty vehicles in South Africa before World War II. South Africa abandoned the technology and went on to pioneer making fuel from coal instead.
The transesterification refining process creates esters from vegetable oil by using an alcohol in the presence of a catalyst. This reaction takes a triglyceride molecule, or a complex fatty acid, neutralizes the free fatty acids and removes the glycerin, thereby creating an alcohol ester. One method of transesterfication mixes methanol with sodium hydroxide and then aggressively mixes the resulting methoxide with vegetable oil, which results in a "Methyl Ester".

I surf the internet today and find this brief and comprehensive case study on how to convert diesel engine to run with biodiesel. Introduction and Fuel Types Now that gas prices have gone through the roof again folks are going to be hearing a lot about alternative fuels and automotive advancements that save gas. While a lot of attention has been given to new and exotic technologies like hydrogen powered cars and hybrid electric vehicles, a simpler and more time-tested solution exists in the form of biodiesel and vegetable oil fuels. Instead of expensive new technologies, the trusty diesel engine running domestically grown bio-fuels and/or used cooking oil is suddenly being rediscovered as a viable alternative. On this page, you'll learn more about biodiesel, and about the process of converting a used Mercedes Benz diesel to run on vegetable oil. The process described in this article, and much of its content, was inspired by another article written by Lyle Pearl of Santa Fe, NM. You can also download and read Lyle's original article in PDF format to supplement this article. |
