Study of Cationic Impregnation Method on Zeolite Catalyst for Upgrading of Methanol to Gasoline (MTG)Process, Ph.D. Dissertation Sharif University of Technology ; Ghanbari, Bahram (Supervisor)
Abstract
In the present research, the conversion of methanol to hydrocarbons was studied over a new series of mesoporous low-silica HZSM-5 (Si/Al=11) catalysts impregnated with cations such as Fe, Zn, Mo and Cr. A systematic study on the effect of stepwise modification of the catalysts for the conversion of methanol to gasoline (MTG) was undertaken in a fixed-bed tubular reactor under ambient pressure at 375 °C, feeding with weight hourly space velocity (WHSV) of 2 h−1. The catalysts were prepared in the absence and presence of cationic promoted factors, in both alkaline and neutral aqueous solutions. The final catalysts characterized by using Fourier-transform infrared, X-ray diffraction, X-ray...
