Abstract

Biodiesel production has traditionally been converted using homogeneous acidic or basic catalysts, but both have limitations. In this paper, a functionalized recyclable porous chitosan-based composite catalyst (ZNC) was developed using activator activation during the catalyst preparation process. XRD, SEM, BET, TGA, and FT-IR were used to confirm the successful synthesis of the catalyst. Activators have been found to affect the growth of the skeleton, providing a great porous texture for the carbon skeleton, which can greatly improve the catalytic performance. As expected, the exposed metal sites and functionalized nitrogen of ZNC materials play a key role in the conversion of soybean oil during the preparation of biodiesel. The higher biodiesel yield (95.33 %) was obtained at the defined condition (calcination temperature = 750 °C, calcination time = 5 h, ZnCl2 concentration = 30 %, NH3·H2O concentration = 30 %, reaction temperature = 60 °C, reaction time = 6 h, catalyst loading = 1 wt%, methanol/oil molar ratio = 6:1). The catalyst has higher catalytic.
