SAPO-34 Zeolite,Zeolite SAPO-34,SAPO-34Molecular Sieve
Microporous molecular sieve is SAPO-34, chabazite, the molecular sieve having a crystal structure similar to, began to be widely used in recent years, many in catalysis, adsorption and the like. Wherein the reaction catalytic conversion of methanol to light olefins (MTO) in, SAPO-34 exhibits extremely excellent catalytic performance, are considered special catalyst MTO reaction. MTO project also appears as SAPO-34 molecular sieve and mushroomed rise at home and abroad. In addition to the MTO reaction, SAPO-34 possess high temperature hydrothermal stability and a suitable pore structure and acidity to make the skeleton in automobile exhaust purification catalyst carrier application areas also show excellent performance. In addition, the adsorption gas separation of SAPO-34 molecular sieves are also widely used, such as the separation of gas methane and carbon dioxide: As has the SAPO-34 molecular sieve high specific surface area and its pore size and methane molecules quite, but greater than carbon dioxide molecular size, so that in the field of methane and carbon dioxide separation has unparalleled advantages.
