Characteristic and superiority | |||
The The molecular sieve pore volume is 0.42cm3 / g, the space symmetric group R3m, belonging to the triclinic system, has a similar structure with chabazite. Has a special water absorption and proton acid. |
Application | |||
SAPO-11 molecular sieve has a one-dimensional pore structure composed of ten-membered ring, with low cracking and deuteration activity, high isomerization and alkylation activity and excellent anti-carbonation performance; for xylene isomerization, toluene The methylation reaction has a high para-selectivity. It can be used as an active component and a carrier of a catalyst in a reaction such as isomerization dewaxing, selective hydrogenation and cracking, aldol condensation or the like. |
Precautions of usage | |||
SAPO-11 molecular sieve is not toxic, but improper use may cause respiratory tract, eye irritation, direct contact may cause dry skin. It is recommended to wear masks and gloves when used. |
