The MACT standards often necessitate the use of advanced emission control technologies, many of which rely on catalytic processes. Catalysts are crucial for reducing emissions of harmful pollutants such as nitrogen oxides (NOx), sulfur oxides (SOx), carbon monoxide (CO), and volatile organic compounds (VOCs). By facilitating chemical reactions at lower temperatures and with higher efficiency, catalysts help achieve compliance with emission limits set by the MACT standards.
