With the increase in the interest about renewable fuel, the researches about more efficient methods of reaction had
been increasing as well. Nowadays, the biodiesel is synthesized by the reaction between soy oil and methanol with
homogeneous catalyst. This route generates a high amount of wastewater in addition the glycerin is impure which ends up
being aggregate to the wastewater because the price of purification is higher than the pure glycerin. An alternative is the use
of heterogeneous catalyst because they don?t generate wastewater and the byproduct is pure glycerin. The present work, focus
in the synthesis of nanoparticulated
-alumina doped with yttrium as heterogeneous catalyst in the synthesis of biodiesel.
The doping altered the characteristics of the material, like the surface area 69.54m2/g to 226.13m2/g and density 4g/cm3
to 2.5g/cm3. The doped
-alumina powder was compressed and it was used a heterocoagulation method to create a porous
material to increase the contact area of the pellet. The catalyst worked in the synthesis of biodiesel, High-performance Liquid
Chromatograph (HPLC) indicated the presence of components of the biodiesel, even with the low yield.
