This study comparatively investigates the catalytic activities and degradation kinetics of produced biodiesels using kaolinite-based heterogeneous catalysts to examine stability. The performance was tested under same operating parameter (methanol/oil ratio, 5:1, at 200 °C for 6 h). obtained biodiesel analyzed TGA equipment obtain yield, as well kinetic parameters. It observed that solid superac...
