The high fuel efficiency of natural gas makes it an attractive alternative to coal and oil during the transition towards renewable energy resources. Natural gas engines are needed to ensure a stable power grid that can accommodate fluctuations in renewable energy production. Unfortunately, these engines emit as much as 3-4% of the methane (CH4) in the natural gas under learn-burn conditions. This methane slip has a high environmental cost since CH4 is a potent greenhouse gas. Complete catalytic oxidation of CH4 can potentially control the emission. Unfortunately, the best performing Pd/Al2O3 catalysts suffer from severe deactivation under operating conditions. After decades of little progress, zeolite-supported catalysts have recently attracted increased attention. Here, we review the current status, challenges, and prospects for controlling methane emissions from large engines using zeolite-based catalysts. The determining factors for catalytic activity and stability are the zeolite topology, alumina content, counter-ion, and active metal nanoparticles incorporation. In addition, we highlight the importance of testing under realistic operation conditions. Thus, the review provides a framework for developing a catalyst technology critically needed to fulfill the Paris Climate Agreement. |
