摘要
以橡胶籽油为原料制备橡胶籽生物柴油,通过运用相关的物性数据估算方法,估算得到了橡胶籽油及其生物柴油的基本物性参数,有效地解决了部分临界性质(如临界温度难以测定的问题);同时估算出包括气体黏度、液体黏度、液体热导率、表面张力、纯溶液饱和密度、理想气体热容和纯液体热容在内的与传递性质和平衡性质有关的物性参数;分别测定了不同温度下橡胶籽油及其生物柴油的相关物性,并与估算所得结果进行对比。模拟结果表明,在实验温度下,橡胶籽生物柴油运动黏度的最大误差为4.32%,表面张力的最大误差为3.82%,橡胶籽油及其生物柴油其他的相关物性参数与实测值误差均在5%以内。
The rubber seed oil was used as raw material to prepare rubber seed biodiesel. The basic physical properties of the rubber seed oil and the biodiesel were estimated by using relevant physical property data estimation methods,which effectively solved some problems of critical properties(such as the critical temperature is difficult to measure). It was also estimated that the physical properties related to transfer property and equilibrium property including gas viscosity,liquid viscosity,liquid thermal conductivity,surface tension,pure solution saturation density,ideal gas heat capacity and pure liquid heat capacity. The relevant physical properties of the rubber seed oil and its biodiesel at different temperatures were measured and compared with the estimated results. The simulation results showed that the maximum error of the kinematic viscosity of the rubber seed biodiesel was 4.32% and the maximum error of the surface tension was 3.82%. The errors of other related physical parameters and measured values of the rubber seed oil and the biodiesel were within 5%.
