Overview

Randomized trial shows efficient biodiesel production in waste valorization, highlighting sustainable catalytic solutions.

Key Points

  • This research aims to develop cost-effective calcium-based catalysts from agricultural waste for biodiesel production.
  • Prepared calcium catalysts by pyrolyzing rice husk and eggshell mixtures at various mass ratios.
  • Investigated structural and catalytic properties for soybean oil transesterification under mild conditions.
  • Characterized materials using FTIR, XRD, SEM-EDS, and BET analyses.
  • Achieved FAME yields of 81.2% for P_RH:ES_1:2 and 71.2% for P_RH:ES_1:1 catalysts.
  • Increased surface area from 0.73 to 49.56 m2 g−1 due to carbonaceous structural modification.
  • Demonstrated good reusability with minimal activity loss.
