What is a Molecular sieve? A molecular sieve, also known as zeolite or zeolite, is a crystalline aluminum silicate. Its crystal structure has a regular and uniform pore, pore size for the molecule of the order of magnitude, and it only allows the diameter of the smaller molecules to enter so that it can screen the molecules in the mixture according to the size. Therefore, it is called molecular screening. More than 200 years ago, B. We were the first to name aluminum silicate zeolite, and the chemical composition formula M and n are metal ions and their valence numbers; x is the number of molecules of silica; y is the number of molecules of water; p is the number of atoms of aluminum; q is the number of atoms of silicon. A molecular sieve is used as a solid adsorbent in the chemical industry, and the adsorbed material can be desorbed, and the molecular sieve can be recycled after use.
Main uses of Molecular sieve In the natural gas sector, It can be used for drying and purification; In the oilfield gas field, For oil cracking gas, light oil thousand dry, olefin drying, Drying of polymerized solvents (hexane, cyclohexane, shine, etc.), Purification of benzene, toluene, and xylene, The drying of the chloride solvent, Drying and purification of alkane agents (acetone, ethers, liquidness, esters), Fluoride refrigerant drying, etc.; In the gas field can be used for air dehydration, off CO2, The separation of oxygen and nitrogen in the air, Drying and purification of protective gas for heat treatment furnace; besides, a Molecular sieve can also be used as a refrigerator (freezer) refrigerant purification, drying, Removal of trace water from the paint. It can also be used as an ion exchange agent, petroleum dewaxing, detergent additive, catalyst and support body. Classification of the molecular sieve: An acid catalyst, using the surface acid of the molecular sieve for catalytic reaction; dual function catalyst, the molecular sieve can load platinum and metals, get the dual function molecular sieve catalyst with metal catalytic function and acid catalytic function; elective catalyst, because the catalytic effect of the molecular sieve generally occurs in the crystal space, the pore size and pore structure of the molecular sieve has a great impact on the catalytic activity and selectivity. The molecular sieve has a regular and uniform crystalline pore, and the pore size is close to the molecular size, so the catalytic performance of the molecular sieve changes significantly with the geometric size of the reactant molecule, product molecule, or reaction intermediate. Price of Molecular sieve The different price of Molecular sieve purity is also different. The market price of Molecular sieves is in the process of dynamic change.
