Abstract
Palladium, platinum bimetallic catalysts supported on η-Al2O3, ZSM-5(23) and ZSM-5(80), with and without the addition of TiO2, were prepared and used for low temperature total methane oxidation (TMO). The catalysts were tested under reaction temperatures of 200-500 °C with a GHSV of 100,000 mL g-1 h-1. It was found that all four components, palladium, platinum, an acidic support and oxygen carrier were needed to achieve a highly active and stable catalyst. The optimum support being 17.5% TiO2 on ZSM-5(80) where the T10% was observed at only 200 °C. On addition of platinum, longer time on stream experiments showed no decrease in the catalyst activity over 50 h at 250 °C.
