چکیده
|
In this study, two new ni/laal2o3 catalysts were prepared by a solgel method, with different aluminium precursors (aluminium triisopropoxide and aluminium nitrate). the catalysts were characterized by scanning electron microscope (sem), xray fluorescence (xrf), xray diffraction (xrd), bet specific surface area, and particle size analysis (psa) techniques. the bet results showed that the particles obtained from the aluminium nitrate precursor had a larger surface area (203 m2/g). the psa data showed particle size distributions between 435 and 754 nm for the catalyst prepared from aluminium triisopropoxide. finally, the catalysts were evaluated for the dechlorination of monochlorobenzene (mcb).
