開發替代能源是刻不容緩的課題，而其中生質柴油(Biodiesel)受到各國重視。生質柴油透過轉酯化反應可將動植物油脂與低碳數醇類經觸媒催化而成，本研究利用basic oxide-supported on 沸石當作轉酯化反應的觸媒，從合成沸石、離子交換改質到轉酯化反應進行一系列的研究，並藉由改變反應參數溫度、反應物比例等建立轉酯化反應較佳的條件。 ;The present proposal will be undertaken with the following objectives:• To develop novel catalysts using alkali and alkaline earth metal oxides supported on various mesoporous materials and naturally occurring clay minerals for transesterification of Jatropha curcas oil in a fixed bed reactor.• To synthesize mesoporous materials such as mesoporous silica (SBA-15), mesoporous zirconia, mesoporous ceria and mesoporous carbon by template method.• To modify the basicity of the synthesized mesoporous materials by impregnation/incorporation of alkali metal oxides (Na, K) and alkaline earth metal oxides (CaO, MgO).• To modify naturally occurring clay minerals such as sepiolite and montmorillonite by alkali metals and alkaline earth metals.• To characterize the supports and the catalysts by the following techniques: XRD to confirm phase formation. BET surface area to measure surface area of supports and catalysts. SEM & TEM to study the surface morphology of the catalyst. XPS to identify the different metallic and oxidic species in the catalyst. UV-Vis DRS to find out the different environment of the active species. Chemisorption studies to find out the percentage dispersion of active metal components. Acidity measurements etc.• To optimize preparation conditions and the loading of alkali and alkaline earth metals for transesterification of Jatropha curcas oil in a fixed bed reactor.• To optimize reaction parameters such as methanol/oil ratio, catalyst weight, reaction temperature and reaction pressure.• To correlate the physicochemical properties of the modified catalysts and the reaction results.
