Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …

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 …
