Abstract


With the growing shortage of oil resources and the enhancement of people 's awareness of environmental protection , to find a way to replace petroleum fuels and environmental pollution renewable energy is on the agenda . Biodiesel much of attention with its advantages of renewable and environmentally friendly . Soybean acid oil as raw material to produce bio- diesel , can not only solve the problem of the current high price of biodiesel feedstock , but also to solve the vegetable oil refinery, oil feet disposal problem of environmental pollution caused by improper , has good economic and social benefits. Therefore , the use of soybean acid oil biodiesel synthesis has important research significance . In this paper, anhydrous ferric chloride catalyzed pre- esterification reaction , the potassium hydroxide catalyzed transesterification reaction process to produce bio- diesel . Compared to traditional step esterification process can greatly reduce the alcohol - oil ratio , and the esterification reaction time is greatly shortened . Then microwave-assisted base-catalyzed transesterification of fatty acid esters of glycerol conversion rate of acidification oil has greatly improved . Biodiesel yield to 91.5% from 82.1% of the conventional method . The production of bio- diesel process simulation model , the use the experiment proceeds powerful data and ChemCAD of material balance and energy balance function , accounted for the established process model simulation results with actual production data consistent , indicating that the model can be compared to predict the performance of the entire process of production . On this basis, the use ChemCAD sensitivity analysis and optimization analysis of the model as a whole and some of the key unit module tuning , and ultimately achieve the purpose of optimizing the entire process .
