JMZ-1S, a CHA-containing molecular sieve and methods of preparation

A composition comprising a silicoaluminophosphate molecular sieve crystal having a CHA framework, as synthesized and in an anhydrous state, comprising a pentavalent phosphorus oxide, a trivalent aluminum oxide, a tetravalent silicon oxide, and having a trimethyl(cyclohexylmethyl) ammonium cation present in the crystal structure, wherein the molecular sieve crystal is free of substituted or unsubstituted 5,4-azonium anions and is free of ammonium anions having a substituents selected from bridged polycyclics, cycloaryls, heterocyclics, cycloalkyls other than cyclohexylmethyl, and C2-C4 alkyls.

A calcined zeolite comprising a framework structure comprising a CHA type framework with phosphate within the framework, where the molecular sieve is a silicoaluminophosphate, the molecular sieve having a SiO2/Al2O3 (SAR) of between 0.45 to 0.55 inclusive, a P2O5/Al2O3 (PAR) ratio of between 0.75 to 0.85 inclusive, and having a characteristic X-ray powder diffraction pattern comprising 2-theta positions at 9.57 (VS), 13.01 (M), 16.17 (W), 17.89 (W), 20.82 (M), 23.29 (W), 25.12 (W), 26.22 (W), 30.99 (W), 31.34 (W)±0.2 with the corresponding relative intensity shown in parenthesis, wherein the zeolite does not comprise a structure directing agent (SDA).
