Fig. 32. CF MAS NMR spectra recorded during the conversion of C-enriched methanol ((U/ F = 100 gh/mol) on calcined zeolite HY (nsi/ Ai = 2.7) at reaction temperatures of 393 K (a), 433 K (b), and 473 K (c). The spectra on the left-hand side were obtained with MAS NMR and proton decoupling (HPDEC), and the spectra on the right-hand side were recorded with the CP technique. Asterisks denote spinning sidebands. Reproduced with permission from (74). Copyright 2001 American Chemical Society. Fig. 32.

The content of crystalline ferric oxide in the catalyst (relative intensity of X-ray diffraction), the amount of water thermally dehydrated during the calcination (the height of the endothermic peak at about 300° in DTA), and the conversion of polymerization are plotted against the chemical composition of the catalysts in Fig. 11. It is seen from... [Pg.111]
