 Modeling and optimization of transesterification of rubber seed oil using sulfonated CaO derived from giant African land snail (Achatina fulica) catalyst by response surface methodologyFelix Aibuedefe Aisien and Eki Tina Aisien Renewable Energy, 2023, vol. 207, issue C, 137-146 Abstract: Rubber seed oil (RSO) is an abundance of low-cost non-edible vegetable oil and an attractive resource for biodiesel production through transesterification. The study aims to model and optimize the transesterification of RSO to biodiesel using sulfonated CaO derived from snail shells as a bifunctional heterogeneous catalyst. We prepared the raw snail shell (RSS) catalyst by calcination and sulfonated it to produce an acid-activated snail shell (AASS) catalyst. We used the central composite design (CCD) of the response surface methodology (RSM) to model and optimize the transesterification process. The X-ray fluorescence (XRF), Scanning Electron Microscopy (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), and Brunauer-Emmett-Teller method (BET) were used to characterize RSS and AASS catalysts.
