In this investigation, a series of NiO/ZSM-5 with different NiO loads were produced and applied to catalyze transesterification of rubber seed oil (RSO) with methanol. ZSM-5 was prepared using hydrothermal technique from rice husk silica (RHS) and Al(OH)3 without using a template and then impregnated with Ni(NO3)2 solution of different concentrations followed by 6 hr calcination at 600 °C. Characterizations were performed with Fourier transform infrared (FTIR) spectroscopy, x-ray diffraction (XRD), scanning electron microscope (SEM), and x-ray fluorescence (XRF). The establishment of ZSM-5 was confirmed by XRD and SEM, and NiO/ZSM-5 by XRD, SEM, and XRF. Catalytic activity tests demonstrate a significant enhancement of performance of NiO/ZSM-5 compared to that of ZSM-5 without NiO. Practically complete conversion of RSO into methyl esters was achieved with the use of NiO/ZSM-5 catalysts prepared using 5, 10, and 15% nickel solution; however, decreases with the use of 20% nickel solution. In this respect, it can be concluded that a 5% nickel solution is sufficient to produce NiO/ZSM-5 enabling complete conversion of RSO into biodiesel, suggesting that NiO/ZSM-5 is a prospective heterogeneous catalyst for biodiesel production.
