ZSM-5 has two sets of intersecting channels, one is straight and the other is zig-zag type perpendicular to each other. The channel is elliptic, and its window diameter is 0.55-0.60nm. It has the structure features that it is crystalline aluminium silicate composed of ten-memberd ring channels in the vertical and horizontal orientation.
High catalytic activity
Long operating life
The larger specific surface area increases the metal's load.
