Introduction
Zeolite catalyst ZSM-23 (Zeolite Socony Mobil-23 or ZSM-23 zeolite powder), is a synthetic zeolite with a crystal type of MIT. The skeleton of ZSM-23 is ten-membered rings, consisting of one-dimensional, non-crosslinked parallel channels, and the pore size is approximately 0.45 nm×0.52 nm.
The notable feature of ZSM-23 molecular sieve is its straight one-dimensional channels, small pore size, compact structure, strong diffusion confinement, and tunable acid properties, thus exhibiting excellent shape-selective catalytic capabilities. The core advantage of ZSM-23 zeolite is its shape-selective catalytic ability brought about by its small pores, which is particularly important in the fields of n-alkane isomerization and catalytic dewaxing.
Due to its good acid catalytic capabilities and excellent shape-selective catalytic properties, ZSM-23 zeolite catalyst has demonstrated outstanding performance in the petrochemical industry, such as olefin oligomerization, hydroisomerization, aromatic alkylation and isomerization, and selective cracking.
