This methane oxidation catalyst addresses the long-standing challenge of sulfur-induced catalyst deactivation and maintains more than 80% methane conversion even after 1,000 hours of continuous operation at an inlet gas temperature of 350℃. Furthermore, platinum (Pt) particles, which serve as the active sites for catalytic reactions, undergo sintering under high temperature operating conditions, resulting in reduced catalytic performance. Features of Technology Developed in this ProductUsing a proprietary technology, TANAKA’s MOC1-30 methane oxidation catalyst converts sulfur adsorbed on the catalyst surface into sulfur trioxide (SO 3 ) while maintaining the bonding between Pt particles and the catalyst support. For decades, TANAKA has developed a wide range of precious metal catalysts for applications including emission control and energy-related technologies. Over many years, TANAKA has manufactured and sold precious metal products for industry and provided precious metals in such forms as jewelry and assets.
