Mesoporous SBA-15-Pr-SO_3H Catalysed Biodiesel Production from Maize Acid Oil

摘要

Mesoporous SBA-15-Pr-SO3H catalyst has been synthesized via one-pot co-condensation method. The synthesized catalyst has been characterized by small and wide angle XRD, SEM-EDS, BET surface area, FT-IR, C-13 and Si-29 CP-MAS-NMR and TGA analysis. The performance of SBA-15-Pr-SO3H catalyst was evaluated in biodiesel production from low-cost maize acid oil (MAO) feedstock containing high free fatty acid (127.21 mgKOH / g). Optimization of various reaction parameters has been carried out using Box-Behnken design (BBD). Under optimized reaction condition, 99.53% biodiesel conversion is obtained.
