标题 Biodiesel Biodiesel is made by vegetable oil or animal fat. Traditional diesel Is made by fossil fuels ------------------------------------------------------------------------- 标题 Benefits for using Biodiesel 1: It provides a market for excess production vegetable and animal fats 2: It decrease, although will not eliminate, the country’s dependence on imported petroleum 3: Biodiesel is renewable and does not contribute to global warming due to its closed carbon cycle. A life cycle analysis of Biodisel showed that overall toxic gas emissions were reduced by 78% compared with petroleum-based diesel fuel. 4: When added to regular fuel in an amount equal to 1~2%, It can be convert fuel with poor Iubricating properties, such as modern ultra-low-sulfer diesel fuel, into an acceptable fuel. --------------------------------------------------------------------------------- 标题 Biodiesel produce Biodiesel is produced by transesterifiction reaction. http://www.pixnet.net/photo/master920735/74520791 --------------------------------------------------------------------------------- 标题 How to do it in laboratory 1: Add NaOH to Methol and dissolve completely(PS: You have to use CSTR (continuous stirred-tank reactors) because it is for a long time). 2: Add material (vegetable oil or animalfat) to Methol solution. 3: Stirrer in the temperature you like (313K~353K) the temperature higher the reaction rate quicker you get 4:Percolating the solution and put the solution you do in the separating funnel and set free it 12~24 hours 5: Use many separating methods to separate solution. (there are many compounds and elements in it but we only need Biodiesel) ------------------------------------------------------------------------------- 标题 Main issues 1: Soup and water is too much. 2: Separate solution is very hard. 3: Make quantitative to product is very hard and slow. 4: There are many unknown substance in waste cooking oil. 5: Vegetable oil and animal fats are more expensive than petroleum. --------------------------------------------------------------------------------- 附上图片集^^ http://www.pixnet.net/album/master920735/13308998 -- 网路上嘴炮靠手指 现实中嘴炮靠舌头 网路现实都嘴炮 可以考虑当AV男优 --
