Effect of Al2O3 and CeO2 Nanocatalysts on Biodiesel Yield from Pine and Soapnut Oils
Abstract: Abstract This study examines the influence of aluminium oxide (Al2O3) and cerium oxide (CeO2) nanocatalysts on the biodiesel yield obtained from two non-edible oils: pine oil and soapnut oil. Both oils were extracted through mechanical pressing and converted into biodiesel using the transesterification process. To understand how different process conditions, affect biodiesel production, a Box–Behnken Design (BBD) was used. Three key variables—methanol-to-oil ratio, catalyst concentration, and reaction temperature—were analyzed to …
