SSZ-13 molecular sieve is widely used in catalytic applications, particularly in the selective catalytic reduction (SCR) of nitrogen oxides (NOx) in exhaust gases from diesel engines. Its unique pore structure and acidity make it highly effective in converting harmful NOx emissions into nitrogen and water, contributing to cleaner air and compliance with environmental regulations. Additionally, SSZ-13 is employed in gas separation processes, such as the purification of natural gas by removing carbon dioxide and other impurities. Its stability and efficiency also make it suitable for use in methanol-to-olefins (MTO) reactions, where it helps convert methanol into valuable olefins like ethylene and propylene, which are essential feedstocks in the chemical industry.
