摘要

采用随机优化设计方法,对以原料和热粘土为催化剂,以橙籽油为原料生产生物柴油的工艺参数进行了分析。设计采用响应面法(全分数阶乘),该方法确定了各个设计点的数值性和离散性。过程优化通过改变五个因素来执行,每个因素在两个不同的水平上。优化过程以甲醇油摩尔比(mol/mol)、催化剂浓度(重量%)、反应时间(min)、温度(℃)和搅拌速度(转/分,rpm)为自变量(输入),以生物柴油产率(vol/vol)为因变量(响应)。利用Design Expert Software (version 12.0)完成设计矩阵、三维曲面图、等高线图和方差分析(ANOVA),并对生物柴油的最佳产率进行了预测和实验,以确定参数的交互效应。相关回归系数表明,该模型对生土和热土具有满意的性能。以原料和热粘土为催化剂,以橙籽油为原料制备生物柴油的实验和实际最优产率分别为79.53和94.58% v/v,预测产率分别为79.55和92.98% v/v。实验条件为:时间150分钟,温度65℃,甲醇/样品摩尔比12:1,催化剂浓度3.0 wt. %,搅拌速度300 rpm。结果表明生物柴油的实际产率与预测产率是一致的。结果表明,以热改性粘土为催化剂制备生物柴油的产率最高。

Effects of process parameters variations and optimization of biodiesel production from orange seed oil using raw and thermal clay as catalyst
In this study, process parameters for the production of biodiesel from orange seed oil using raw and thermal clay as catalyst were analyzed using randomized optimal design. The design was a response surface method (full fractional factorial) which identified the various design points as being numerical and discrete. The process optimization was performed by varying five factors, each at two different levels. The process parameters: methanol to oil molal ratio (mol/mol), catalyst concentration (weight %), reaction time (minutes), temperature (°C) and agitation speed (revolution per minutes, rpm) were the independent variables (input), while the biodiesel yield (vol/vol) was the dependent variable (response) in the optimization process. The designed matrix, 3D (three dimensional) surface plots, contour plots and analysis of variance (ANOVA), was achieved using the Design Expert Software (version 12.0), the optimum biodiesel yield was predicted and experimented to ascertain the interactive effects of parameters. The correlating regression coefficient indicated the satisfactory performance of the model for the raw and thermal clay. The experimental/actual maximum optimal biodiesel yield for the biodiesel production from the orange seed oil using raw and thermal clay as catalyst was 79.53 and 94.58% v/v while the predicted biodiesel yield was 79.55 and 92.98% v/v. The set of conditions that caused these positive effects were established at Time of 150 minutes, Temperature 65 °C, methanol /sample molal ratio of 12:1, catalyst concentration of 3.0 wt. % and agitation speed at 300 rpm respectively. Thisresults shows agreement between the actual and predicted biodiesel yield. It can be concluded that the best biodiesel yield can be achieved using thermally modified clay as catalyst.
