摘要：

The potential of hierarchical H-ZSM-5 zeolites was studied for the conversion of DME to fuel-compatible hydrocarbons. For this purpose, hierarchical H-ZSM-5 zeolites have been prepared from commercial H-ZSM-5 by desilication and organosilane-directed hydrothermal synthesis. The zeolites were characterized by X-ray diffraction, NH3-TPD, DRIFTS, and N-2 physisorption measurements. The catalysts have been tested in a tube reactor (1 bar, 648 K). The results indicate important structural changes in framework and acidic sites, which are significant for the synthesis of gasoline-range hydrocarbons.
