摘  要：
为研究采用固体碱催化剂催化制备生物柴油的相关技术,以棉籽油为对象,选用Na3PO4/MgO负载型固体碱为催化剂,以棉籽油的生物柴油转换率为指标,通过单因素和正交试验,分析催化剂的最佳制备工艺,并对催化剂进行X射线衍射、扫描电镜和热重表征分析。在此基础上对该催化剂催化棉籽油制备生物柴油的工艺进行探讨。研究结果表明,催化剂的最佳制备工艺为:Na3PO4负载量32%,焙烧温度600℃,焙烧时间3h,共混温度70℃;使用优选的催化剂制备生物柴油的工艺条件为:反应时间2.5h,反应温度70℃,醇油摩尔比15:1,催化剂用量5%;催化剂的活性与Na3PO4晶相有关。

摘  要：
In order to study the related technology for preparing biodiesel by transesterification of cottonseed oil using solid based catalyst,with supported solid base Na3PO4/MgO as catalyst and biodiesel conversion rate as index,the optimum conditions for catalyst preparation were analyzed by single-factor and orthogonal experiments.The catalyst was characterized by methods of XRD,SEM and TG.Furthermore,the transesterification conditions from cottonseed oil to biodiesel were investigated using solid base catalyst.It was obtained that the optimum conditions for catalyst preparation were:32% of Na3PO4 dosage on MgO,600℃ of roasting temperature,3 h of roasting time and 70℃ of blending temperature.Catalytic activity was related to Na3PO4 crystalline phase.The optimal conditions of transesterification with optimized catalyst were:2.5 h of reaction time,70℃ of reaction temperature,15:1 of mass ratio of methanol to oil,5% of quality ratio of catalyst to oil.
