Zeolites
______
Zeolites are truly indispensable in many catalytic processes, such as methanol-to-olefin reaction, fluid catalytic cracking, hydrocracking, dewaxing, and Fischer-Tropsch synthesis. More recently, zeolites have also been introduced for catalytic emission control, e.g., reducing the emission levels of nitrogen oxides (NOx) from both stationary and mobile sources. In particular, zeolites promoted with transition metals such as copper and iron have been proven to be active for the selective catalytic reduction of NOx by ammonia (NH3 -SCR), which is currently considered as one of the preferred technologies for NOx removal from lean exhaust gases in automotive applications. To dramatically increase its lifetime, the zeolite must remain stable at elevated temperatures. Among all zeolites, only CHA topology SSZ-13 has this outstanding property.
We have developed a new process to produce CHA SSZ-13 zeolite and CHA-Cu SSZ-13 zeolite resulting in a significant reduction of production cost while increasing material performance.
