Effect of Steaming on Waste‐Derived Zeolite ZSM‐5 as Methanol‐To‐Hydrocarbons Catalyst

The valorization of low-grade industrial residues into valuable materials has been a way to reduce the impact industry on planetary boundaries. Silicon-rich wastes have used for zeolite synthesis while impurities originating from vital role in physicochemical properties and catalytic performance waste-derived zeolites. Here, effect steaming zeolites were investigated. Steamed ZSM-5 maintained their structure Brønsted acidity was decreased significantly due dealumination. Electron paramagnetic resonance revealed that samples resulted re-dispersion Fe phases. exhibited high amount weak intermediate upon steaming. Interestingly, sample with higher had an increase Lewis steaming, testing Methanol-to-Hydrocarbons reaction 10 % conversion 4 propylene yield.
