  • Publication number: 20200171472
    Abstract: JMZ-1, a zeolite having a CHA structure and containing trimethyl(cyclohexylmethyl)ammonium cations as a structure directing agent is described. A calcined zeolite, JMZ-1C, that does not contain a structure directing agent, is also described. Metal containing JMZ-1C has improved SCR activity compared to CHA-containing zeolites having the same metal loading and comparable silica:alumina ratios (SAR). Methods of preparing JMZ-1, JMZ-1C and metal containing calcined counterparts of JMZ-1C are described along with methods of using JMZ-1C and metal containing calcined counterparts of JMZ-1C in treating exhaust gases.

  • Patent number: 10413890
    Abstract: STA-19, a molecular sieve having a GME structure and phosphorus in the framework, is described. STA-19AP (as prepared) can have a lower alkyl amine, such as trimethylamine, and olig-(1,4-diazabicyclo[2.2.2]octane)-pentyl dibromide ([DABCO-C5]x where x represents the number of repeating units) or olig-(1,4-diazabicyclo[2.2.2] octane)-hexyl dibromide ([DABCO-C6]x) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide (TBAOH), can be used as a pH modifier for the preparation of SAPO-STA-19. A calcined product, STA-19C, formed from STA-19AP is also described. Methods of preparing STA-19AP, STA-19C and metal containing calcined counterparts of STA-19C are described along with methods of using STA-19C and metal containing calcined counterparts of STA-19C in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

  • Patent number: 10213776
    Abstract: STA-20, a molecular sieve having a new framework type, is described. STA-20AP (as prepared) can have an alkyl amine, such as trimethylamine, and 1,6-(1,4-diazabicyclo[2.2.2]octane) hexyl cations (from diDABCO-C6) as SDAs. A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide, can be used as a pH modifier for making SAPO STA-20. A calcined product, STA-20C, formed from as made STA-20 is also described. Methods of preparing STA-20, activating STA-20 by calcination, and metal containing calcined counterparts of STA-20 are described along with methods of using STA-20 and metal containing calcined counterparts of STA-20 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

  • Patent number: 10029239
    Abstract: The invention relates to a method of preparing SAPO-56, (AFX) using a lower alkyl amine, preferably trimethylamine, and a 1,4-diazabicyclo [2.2.2]octane derivative, preferably comprising either 1,4-(1,4-diazabicyclo[2.2.2]octane)butyl cations or 1,5-(1,4-diazabicyclo[2.2.2]octane)pentyl cations, as structure directing agents (SDAs). A lower alkyl ammonium hydroxide, such as tetrabutylammonium hydroxide (TBAOH), can be used to control the pH. The invention also relates to SAPO-56 comprising a lower alkyl amine, such as trimethylamine, and a 1,4-diazabicyclo [2.2.2]octane derivative, such as a compound comprising either 1,4-(1,4-diazabicyclo[2.2.2]octane)butyl cations or 1,5-(1,4-diazabicyclo[2.2.2]octane) pentyl cations.
