Introduction
Zeolite NA-ZSM-5 catalyst is the sodium type of ZSM-5 molecular sieve, which also has an MFI structure. The negative charges in the NA-ZSM-5 framework are balanced by Na+ ions. NA-ZSM-5 is the basic form for making H-ZSM-5 and metal-modified ZSM-5, and it is not usually used directly as a strong acid catalyst.
NA-ZSM-5 is the start or source material for all ZSM-5 zeolite catalysts, such as H-ZSM-5, CU-ZSM-5, FE-ZSM-5, etc. NA-ZSM-5 zeolite has a complete structure, clean channels, high plasticity, and is easy to modify and exchange.
NA-ZSM-5 has excellent hydrothermal stability, is not prone to carbon buildup, but has no catalytic activity due to its weak acidity.
