I. Product Introduction
Zeolite
ssz-39 belongs to the AEI-type structure, consisting of a three-dimensional
intersecting channel system composed of double six-membered rings (D6R) and
eight-membered rings. The double six-membered rings are arranged crosswise to
form asymmetric pear-shaped cages (AEI cages), with the channel size being
0.38nm×0.43nm.
II. Application
Application of methanol conversion to olefins, especially ethylene and propylene
Denitration of exhaust gas from mobile sources
Denitration of flue gas from stationary sources
