Biodiesel from Adsorbed Waste Oil on Spent Bleaching Clay using CaO as a Heterogeneous Catalyst

Oil-laden spent bleaching clay (SBC) is currently under-utilized by dumping it in landfills without any attempt to recover the oil. Therefore, effort has been made to extract the waste oil using different solvents (methanol, ethanol, petroleum ether, and hexane), and utilize the oil in transesterifi...

Cleaner oil (free from polar components and least acid content) of 28.2 ± 0.6 wt.%, a significant amount susceptible to be converted to biodiesel, was extracted using non-polar solvent.
