Abstract
The promoted K-La nanocatalysts supported on ZSM-5 zeolite were prepared
via wetness impregnation method and tested for biodiesel production from soybean oil. The effects
of different weight percentage of La, loading of K as a promoter and calcination conditions
on structure and activity of catalyst were investigated. Results showed that the supported catalyst
containing 7wt.% of La was promoted with 1wt.% of K is an optimal catalyst for biodiesel
production. The best operational conditions were the CH3OH/oil=12/1 molar ratio at 60˚C with
mechanical stirring 500 rpm for 3 h. The biodiesel yield reached 90% under the optimal
operational conditions. It was found that K-La/ZSM-5 nanocatalyst have high basic sites and
catalytic activity for biodiesel production. Characterization of catalysts was carried out by using
Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Temperature
Programmed Desorption (TPD), X-Ray Diffraction (XRD), Fourier Transform-InfraRed(FT-IR)
spectroscopy and N2 adsorption-desorption measurements methods.
