摘要： A method of forming an AEI-type zeolite in a hydrothermal synthesis without the use of hydrogen fluoride (HF) and in the absence of any FAU zeolite Y. A gel composition formed upon using this method includes one or more sources of silica; one or more sources of alumina, one or more organic structure directing agents (OSDA); a source of alkali metal ions; and water. This gel composition is defined by the molar ratios of: SiO2/AI2O3 16:1 to 100:1; M2O/SiO2 0.15:1 to 0.30:1; ROH/SiO2 0.05:1 to 0.20:1; and H2O/SiO2 5:1 to 20:1; wherein M is the alkali metal ion and R is an organic moiety derived from the OSDA. This gel composition, after reacting at a temperature between 135° C. to about 180° C. for 15 hours to 168 hours forms the crystalline AEI-type zeolite having a silica to alumina ratio (SiO2:AI2O3) that is greater than 8:1.

摘要： A cerium-zirconium oxide-based ionic conductor (CZOIC) material including zirconium oxide in an amount ranging from 5 wt. % up to 95 wt. %, cerium oxide in an amount ranging from 95 wt. % to 5 wt. %, and at least one oxide or a rare earth metal in an amount ranging from 30 wt. % or less, based on the overall mass of the CZOIC material. The CZOIC material exhibits a structure comprising one or more expanded unit cells and a plurality of crystallites having ordered nano-domains. The structure of the CZOIC material exhibits a crystal lattice defined by a d-value measured at multiple (hkl) locations using a SAED technique that exhibit distortions, such that the d-values for the same (hkl) location varies from about 2% to about 5% from the d-value measured for a reference cerium-zirconium material at the same (hkl) location.

摘要： A method of continuously forming AEI-type zeolites in a tubular reactor via a hydrothermal synthesis. A gel composition formed upon using this method includes one or more sources of silica, alumina, organic structure directing agents (OSDA), alkali metal ions; water; and optionally zeolite seeds. This gel composition is defined by the molar ratios of SiO2/AI2O3 15:1 to 100:1; M2O/SiO2 0.15:1 to 0.30:1; ROH/SiO2 0.05:1 to 0.2:1; and H2O/SiO2 5:1 to 20:1; wherein M is the alkali metal ion and R is an organic moiety derived from the OSDA. This gel composition, after reacting at a temperature between 180° C. to about 220° C. for less than 2 hours forms the crystalline AEI-type zeolite having a silica to alumina ratio (SiO2/AI2O3) that is greater than 14:1.

摘要： A crystalline, core-shell hybrid Chabazite (CHA) material for use as a catalyst has a core with a silicon to aluminum ratio (SAR) that is less than 25 and a shell that at least partially encapsulates the core, the shell having an SAR of about 25 or greater. The crystalline, core-shell hybrid Chabazite is prepared by forming a first chabazite (CHA) material having a silicon to aluminum ratio (SAR) that is less than 25, placing the first CHA material into an aqueous reaction mixture comprising one or more precursors capable of forming a second chabazite (CHA) material having an SAR that is 25 or greater, growing the second CHA material on the surface of the first CHA material, and collecting the core-shell hybrid CHA material.

摘要： A method of forming AEI-type zeolites in a hydrothermal synthesis without the use of hydrogen fluoride (HF) and in the presence of an FAU zeolite NaY with SAR ≤5, a Y zeolite with a SAR ≥5, or a combination thereof. A gel composition formed upon using this method includes one or more sources of silica, alumina, organic structure directing agents (OSDA), and alkali metal ions; zeolite seeds; and water. This gel composition is defined by the molar ratios of: SiO2/AI2O3 18:1 to 100:1; M2O/SiO2 0.15:1 to 0.30:1; ROH/SiO2 0.05:1 to 0.13:1; and H2O/SiO2 5:1 to 20:1; wherein M is the alkali metal ion and R is an organic moiety derived from the OSDA. This gel composition, after reacting at a temperature between 135° C. to about 200° C. for 10 hours to 168 hours forms the crystalline AEI-type zeolite having a silica to alumina ratio (SiO2:AI2O3) that is greater than 15:1.
