Abstract

See full text

STA-18, a molecular sieve having a SFW structure and containing phosphorus in the framework, is described. STA-18AP (as prepared) can have a lower alkyl amine, such as trimethylamine, and one of 1,6-(1,4-diazabicyclo[2.2.2]octane)hexyl cations (from diDABCO-C6) or 1,7-(1,4-diazabicyclo[2.2.2]octane)heptyl cations (from diDABCO-C7) or 1,8-(1,4-diazabicyclo[2.2.2]octane)octyl cations (from diDABCO-C8) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide, can be used as a pH modifier for making SAPO STA-18. A calcined product, STA-18C, formed from STA-18AP is also described. Methods of preparing STA-18AP, STA-18C and metal containing calcined counterparts of STA-18C are described along with methods of using STA-18C and metal containing calcined counterparts of STA-18C in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.
