Process for synthesizing a zeolite catalyst on a pH controlled basis to improve catalyst life |
| 摘要 |
A process for preparing a zeolite, e.g. ZSM-5, under controlled conditions of initial pH adjustment with an acid, SiO2/Al2O3 mole ratio, and in the presence of sodium cations, is disclosed, as well as a process for using the same to synthesize olefins from methanol and/or dimethyl ether.
