生物柴油调和燃料理论热值比对分析

摘要

The Jatropha biodiesel,swill-cooked dirty oil biodiesel and rubber seed biodiesel were prepared in laboratory by transesterification,and according to the different volume ratio,36 kinds of biodiesel blend fuels were prepared with the 0# diesel.The theoretical calorific values of blend fuels according to Mendeleev's formula and mass fraction were calculated,and linearly fitted with the mesured calorific value respectively to find out the best calculation method of theoretical calorific value.The results showed that theoretical calorific value according to mass fraction was suitable for the calculation of calorific value of Jatropha biodiesel blend fuel;theoretical calorific value according to Mendeleev's formula was more suitable for the calculation of calorific value of swill-cooked dirty oil biodiesel blend fuel;two kinds of methods were suitable for the calculation of theoretical calorific value of rubber seed biodiesel blend fuel.%通过酯交换法在实验室制备了小桐子生物柴油、地沟油生物柴油和橡胶籽生物柴油,与0#柴油按照不同体积比配制出36种生物柴油调和燃料.计算生物柴油调和燃料的门捷列夫理论热值和质量分数理论热值,分别与测定热值进行线性拟合,得出最佳理论热值计算方法.结果表明:质量分数理论热值计算方法适用于小桐子生物柴油调和燃料;门捷列夫理论热值计算方法适用于地沟油生物柴油调和燃料;两种方法均适用于橡胶籽生物柴油调和燃料理论热值计算.
