Direct conversion of syngas to dimethyl ether as a green fuel over CuO-ZnO-Al2O3/HZSM-5 nanocatalyst: Effect of aging time on physicochemical and catalytic properties

Abstract: The effect of aging time on physicochemical and catalytic properties of CuO-ZnOAl 2 O 3 /HZSM-5 nanocatalyst for direct conversion of syngas to dimethyl ether (DME) has been investigated. Nanocatalysts were synthesized using co-precipitation method in which the aging time varied from 0 to 6 h. The physicochemical properties of the nanocatalysts were studied by X-ray diffraction, Brunauer, Emmett, and Teller, Field Emission Scanning Electron Microscopy (FESEM), energy dispersive X-ray, transmission electron mic… Show more

“…It confirmed that the nanostructure catalysts were crystallized MFI zeolite (HZSM-5 zeolites) . Similar XRD patterns were obtained by others. As can be seen in Figure S1, the intensity of peaks for synthesized HZSM-5 with Si/Al gel ratio 100 was higher than others. Moreover, the crystallization rate can be affected by the amount of aluminum …”

“…Micropore volumes for all nanostructured HZSM-5 were greater than mesopore volumes. Similar findings were also obtained by Khoshbin et al 31 Figure 3 shows the spectra of 27 Al MAS NMR analysis for synthesized HZSM-5 with different aluminum sources with a similar Si/Al gel 30 and the spectra of HZSM-5 synthesized with aluminum nitrate at different Si/Al gel . All catalysts displayed an intense peak at about 55 ppm which corresponded to the tetrahedral aluminum atoms in the catalyst framework.…”
