ZSM11

ZSM-11 is a type of zeolite, which are crystalline aluminosilicate minerals. Zeolites have a porous structure that makes them useful as catalysts and adsorbents. ZSM-11 belongs to the MFI family of zeolites, which also includes ZSM-5. Its framework structure is characterized by a three-dimensional network of interconnected straight and sinusoidal channels.

The synthesis of ZSM-11 typically involves using silica and alumina sources in the presence of a structure-directing agent, often an organic amine or quaternary ammonium salt. The specific synthesis conditions, such as temperature, pH, and reagent concentrations, influence the crystal size and purity of the resulting ZSM-11.

ZSM-11 exhibits high thermal stability and resistance to acidic environments, properties that are advantageous in various industrial applications. Its pore structure, with channel dimensions around 5.1-5.6 Angstroms, allows for selective diffusion of molecules.

One of the primary applications of ZSM-11 is in catalysis. It is widely used in petrochemical processes, particularly in the conversion of methanol to gasoline (MTG) and related reactions. Its shape selectivity, due to its defined pore structure, enables it to favor the formation of specific hydrocarbon products. ZSM-11 can also be employed in the cracking of hydrocarbons, isomerization, and dealkylation processes. Beyond petrochemicals, ZSM-11 finds use in the catalytic conversion of biomass-derived compounds and in environmental catalysis.
