SAPO-11 molecular sieve
SAPO-11 molecular sieve has an AEL structure and belongs to the orthorhombic crystal system. Its framework is mainly composed of silicon, aluminum, and phosphorus tetrahedra interwoven with each other, forming an oval-shaped ten-membered ring one-dimensional straight pore channel.
Characteristics and Applications:
1. It is used for the isomerization of n-butene and the hydro-isomerization of long-chain n-alkanes. SAPO-11 has mild acidity and a unique pore structure, which can prepare high-activity and high-selectivity catalysts for the isomerization of n-butene (conversion of n-butene to isobutene) and the hydro-isomerization of long-chain n-alkanes. Under the action of SAPO-11 molecular sieve, the coking produced by the isomerization of n-butene has little effect on the yield of isobutene, but it has a significant inhibitory effect on the low-temperature dimerization of isobutene. The dimerization reaction only proceeds freely on the external surface of SAPO-11, while the isomerization of n-butene mainly occurs inside the ten-membered ring pore channels of the molecular sieve, thereby increasing the yield of isobutene;
2. It is used in the preparation of catalysts for increasing the octane number of gasoline and hydro-isomerization dewaxing for lubricating oil;
3. The SAPO-11 catalyst is suitable for the conversion of low-carbon olefins (light olefins) into gasoline series products. In the process of propylene polymerization to form liquid gasoline products, it shows high polymerization activity and high shape-selective catalytic ability for liquid products, with good selectivity and high yield;
4. The combination of Fe or Co catalysts with SAPO-11 molecular sieves is used to convert syngas into gasoline components above C5, improving the selectivity and product quality of the process;
5. Alkylation of branched aromatics.
