Pd-Na-MCM-22, Pd-H-MCM-22 and Pt-SAPO-11 catalysts were synthesized and characterized using techniques of X-ray powder diffraction, scanning electron microscopy, FTIR, nitrogen adsorption and X-ray fluorescency. The FTIR spectra of Pd and Pt modified MCM-22 and SAPO-11 exhibited lower amounts of Bronsted (B) and Lewis (L) acid sites than the unmodified MCM-22 and SAPO-11. The catalysts were tested...
