Abstract

See full text

A SAPO-34 molecular sieve and method for preparing the same, whose chemical composition in the anhydrous state is expressed as: mSDA.(SixAlyPz)O2, wherein m is 0.08-0.3, x is 0.01-0.60, y is 0.2-0.60, z is 0.2-0.60, and x+y+z=1. The template agent SDA is in micropores of the molecular sieve. SDA is an organic amine with the structural formula (CH3)2NRN(CH3)2, wherein R is a saturated straight-chain or branched-chain alkylene group with having from 2-5 carbon atoms. There is a slight Si enrichment phenomenon on the crystal surface of the molecular sieve crystal, and the ratio of the surface Si content to the bulk Si content of the crystal ranges from 1.50-1.01. Said SAPO-34 molecular sieve, after being calcined at a temperature range from 400-700° C. in air, can be used as a gas adsorbent and catalyst for an acid-catalyzed reaction or oxygenate to olefin reaction.
