Synthesis and Characterization of Heterogeneous Magnetic Bifunctional Catalyst Derived from Rice Husk for Biodiesel Production from Used Cooking Oil
The fuel properties of the biodiesel reviewed by the ASTMD 6751 method, and it was found to be within allowable limits and has properties almost similar to diesel fuel. To conclude, both of heterogeneous magnetic bifunctional catalysts RHC/K2O-20 wt.%/Fe-5 wt.% and RHC/K2O-20 wt.%/Ni-5 wt.% have the potential in the transesterification of low-grade feedstocks due to high catalytic performance, recovery, reusability, and stability.
