Abstract

In this study, silica extracted from sugascane bagasse was sulfated by wet impregnation method using 0,5 M H2SO4 solution as sulsating agent. The sulfated silica was subsequently subjected to calcination at different temperatures of 100, 400, 600 and 800 C and then test as catalyst for transesterification of coconut oil using methanol. the experimental results revealed that the catalyst exhibit good catalytic performance , enabling the achievement of up to 85% reaction yields. Physical characteristics of the catalysts were investigated using different techniques, including Fourier Infra-Red (FTIR)spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Particle Size Analyzer (PSA). These characterization techniques reveal that succesful sulfation of the silica was achieved.
