Overview

This analysis finds thermal catalysis reduces methane levels in varied environments, suggesting Ag and Ni as cost-effective alternatives to Pd.

Key Points

  • Thermal catalysis achieves over 95% methane conversion at 500 ppm below 500°C, showcasing its efficiency.
  • Pd/CeO2 outperformed other catalysts, yet some Ag and Ni variants provided competitive results at higher temperatures.
  • The study employed a matrix of catalysts with Pd, Ni, and Ag on various supports to evaluate methane oxidation activity.
  • The findings underline the necessary balance between catalyst cost and environmental impact for methane mitigation.
