Synthesis and Characterization of Cerium Oxide Loaded Zno For Biodiesel Production

This work is aimed to produce biodiesel from low-quality oil by heterogeneous catalysts# accordingly, the zno and ceria loaded-zno were prepared through the hydrothermal method and employed in biodiesel production# as-made nanocatalysts were analyzed via different techniques listed as xrd, fesem, and bet-bjh# the results revealed that the nanocatalysts have successfully synthesized and they have a porous structure which is a suitable point for them# also, the ceria loaded-zno has higher pore volume and specific surface area compared to the zno# the catalytic performance tests were carried out at 110°c for 3 hours, with the methanol/oil molar ratio of 12 and catalyst loading of 5% by weight# the result showed high performance for ceria loaded-zno in which the tri-glyceride, oleic acid, and total conversion were determined 70, 92 and 87% respectively#
