Modified mesoporous HZSM-5 catalysts were prepared by controlled desilication using a mixture of NaOH and TPAOH (tetrapropylammonium hydroxide) and impregnation of metals (Mn, Ce, and Ba) and metalloid B. The catalytic performances of all prepared catalysts for methanol to propylene (MTP) reaction were evaluated in a fixed bed reactor under atmospheric pressure at 480°C. The parent and modified catalysts were characterized by XRD, ICP-OES, FE-SEM, NH3 -TPD, FT-IR, BET, and TGA techniques. |
