Research development in purification of glycerol produced from the homogeneous base catalyzed biodiesel
摘要
Abstract
The glycerol and other by-product component from the production of biodiesel by homogeneous base catalysis are introduced. The whole purification process of glycerol produced from the biodiesel is concluded and the changes of the components in the biodiesel by-products during purification are studied. Meanwhile,the main factors (the categories and dosage of dilute,acid species and pH value) which influence the glycerol purification from by-products are analyzed. It is recommended that the combined processes “pretreatment & the purification of crude glycerol” are suitable to generate high purity glycerol,and methanol is often used as diluents for the separation of glycerol from other components under acid condition within the pH of 2.5—4.0(adjusted by phosphoric acid).Then high-purity glycerol can be finally obtained through a series of processes such as vacuum distillation,ion exchange,membrane separation,extraction and molecular distillation followed by decolorization with activated carbon.关键词
