Dealumination of ZSM-5 — Characterization by TPD, DTA/DTG, XPS and Adsorption Measurements
A series of ZSM 5 samples obtained by dealumination is studied by TPD, DTA/DTG, XPS and adsorption measurements. The amount of adsorbed water at p/p 0 ≦ 0.1 and the amount of chemisorbed NH 3 corresponding to the TPD peak at 693–723 K correlate with the number of framework aluminium atoms per unit c...
