zeolite type ZSM-48 - Introduction
ZSM-48 zeolite is a kind of zeolite with high silica to alumina ratio, which has specific crystal structure and chemical properties. The following is a description of some properties, uses, preparation and safety information of ZSM-48 zeolite:
Nature:
1. Structure: ZSM-48 zeolite has a three-dimensional pore structure, forming a cross-arranged straight pipe system in the crystal.
2. Composition: Its chemical composition is mainly composed of silicon, aluminum and oxygen, and has a high ratio of silicon to aluminum.
3. Pore size: the pore size of ZSM-48 zeolite is small, about 0.55 nm, which is suitable for separating small molecules.
4. Surface area: it has a large specific surface area, which is conducive to adsorption of molecules.
Use:
1. Catalyst: due to its special pore structure, ZSM-48 zeolite can be used as a catalyst for various chemical reactions, such as catalytic cracking reaction, reforming reaction, etc.
2. Separation and adsorption: Due to its small pore size, ZSM-48 zeolite can be used for separation and adsorption of small molecules, such as the separation of C6-C8 aromatic hydrocarbons with high selectivity.
Preparation Method:
The preparation of ZSM-48 zeolite mainly adopts hydrothermal method. Under suitable reaction conditions, raw materials such as silicon source, aluminum source and organic template agent are mixed, heated and allowed to stand, the ZSM-48 type zeolite is formed by crystal growth.
Safety Information:
1. ZSM-48 zeolite is relatively safe under general conditions of use, but care should be taken to avoid inhalation of dust or contact with skin and eyes.
2. When handling ZSM-48 zeolite, wear appropriate personal protective equipment, such as gloves and protective glasses.
3. If accidentally inhaled or come into contact with ZSM-48 zeolite, should immediately clean the affected parts, and timely seek medical attention.
4. In the storage and handling of ZSM-48 zeolite, should follow the relevant chemical storage and handling safety regulations.
