Abstract

Preparation of reusable catalyst based on KF-modified kaolinite clay for reusable catalyst application on biodiesel conversion has been investigated. Materials preparation were carried out by simple mixing and solid reaction between KF and kaolinite at various KF loading. The effect of KF content loaded the surface structure and surface basicity have been studied. Characterization of the materials was investigated based on scanning electrone microscopy-energy dispersive-x ray spectroscopy (SEM-EDX) SEM, x-ray diffraction (XRD) and gas sorption analysis. Increasing the reusability and the effectivity of catalysts utilization was studied by comparing reflux method and microwave (MW)-assisted reaction of biodiesel production from Jatropha oil. Results showed that increasing solid basicity is the character plays important role for increasing catalytic activity in biodiesel conversion. By comparing the reaction method, it is found that similar biodiesel yield was obtained with shorter time, higher turnover frequency (TOF) and better reusability over MW assisted-method.
