摘要
Abstract
Biodiesel is a clean and renewable energy,which has drawn more and more attention in recent years. However,the high production cost of biodiesel has hindered its industrial applications. Many strategies including adopting cheap raw materials,efficient catalysts,new technologies and equipments have been developed to solve this problem,among which the development of cheap raw materials should be preferred. The spent bleaching clay from oil plants has a large oil content ranged from 20% to 40%,by recycling which to produce biodiesel can reduce the raw material costs as well as achieve resource utilization of factory waste. This article reviews the current research progress about biodiesel production from spent bleaching clay including the one-step and two-step processes. The two-step process is well developed but is complicated and a large amount of solvent is required. In contrast,the one-step process is simpler and less costly,while the reaction time is longer and the separation of catalysts is more difficult. Therefore,it is necessary to explore a one-step process featured with high reaction rate,high efficiency and easily recycled catalysts in the future.关键词
