sapo-34 zeolite

chemical formula: [ca2+6 (h2o)40] [al12si24 o72]-cha

channels: sapo-34 is a zeolite with a chabazite class structure. si-al-phosphate is its skeleton’s primarycomponent. this zeolite contains six-membered ring and eight-membered ring pairs as well as afour-membered elliptical cross-cha cage and a three-dimensional pore structured ring.

features and applications: used in refining and specialty chemicals markets- shape selectibe catalyst, e.g. methanol toolefin environmental area - catalyst carrier of exhaust purification drying, purification and seperation area.

ssz-13 zeolite,zeolite ssz-13,ssz-13 molecular sieve

ssz-13 molecular sieve having chabazite (cha) structure, which is composed alo4 and sio4 tetrahedra joined by oxygen atoms inclusive, orderly arranged to have eight yuan spheroidal cage ring structure (0.73 nm × 1.2 nm) and three-dimensional intersection pore structure (figure 1), pore size of 0.38 nm × 0.38 nm, a specific surface area of up to 700 m2 / g. since ssz-13 has ordered pore structure, good hydrothermal stability, there is more surface acidic proton center and exchangeable cations and other characteristics,
