Reliability on the observed results of biodiesel prepared from high viscous rubber seed oil (RSO) using fluorite and calcined limestone as catalysts has been studied using uncertainty error analysis. In this study, the error analysis was performed for three different deviations 5, 10, and 15% of optimum process parameter conditions of 12:1 methanol: oil molar ratio (mol/mol), 4 (wt %) of catalyst concentration, and 5(h) of reaction time, respectively. All the uncertainty experiments were performed for upper level and lower level of every deviation mentioned with. From these experiments, it was observed that methanol: oil molar ratio (mol/mol) shows more error on a small deviation of optimum conditions when compared with catalyst concentration and reaction time, respectively. It is also observed that molar ratio is the most sensitive process parameter in biodiesel preparation from RSO using fluorite and calcined limestone as heterogeneous base catalysts when compared to catalyst concentration and reaction time, respectively.

萤石和煅烧石灰石作催化剂的橡胶籽油转化为生物柴油的敏感工艺参数的确定—不确定度分析

使用不确定度误差分析，研究了由萤石和煅烧石灰石作为催化剂的高粘度橡胶籽油（RSO）制得的生物柴油观察结果的可靠性。在这项研究中，对最佳工艺参数条件的三个不同偏差5、10和15％进行了误差分析，最佳条件参数条件是甲醇与油的摩尔比（mol / mol），催化剂浓度4（wt％）和12：1。反应时间分别为5（h）。对提到的每个偏差的上，下水平均进行了所有不确定性实验。从这些实验中观察到，当分别与催化剂浓度和反应时间相比时，在最佳条件的小偏差下，甲醇：油的摩尔比（mol / mol）显示出更大的误差。
