Comparison of catalyst activity between palladium,copper, and iron catalyst in catalytic combustion of methane

摘要

Catalyst used for high-temperature combustion of light hydrocarbon for example methaneudmust maintain high activity over long time intervals by avoiding excessive sintering anduddeactivation in the hot and corrosive combustion environment. This study is carried out toudcompare the catalyst activity between Palladium, Iron and Copper catalyst in the catalyticudcombustion of methane. The characteristics of catalyst are studied with NA and SEM. In thisudcharacterization method, the catalyst morphology and the surface areas of the catalyst canudstudy. This research is carried out in the micro reactor in laboratory scale. The effect c4IudHydrogen Sulphide, H2S poisoning on the combustion of methane over alumina-supported'udalso investigates. From the result obtain, PdfAh03 is the most active catalyst and stableudfollow by CulAh03 and Fe/Ah03. BET characterization shows that, all catalyst loss itsudspecific surface area when poison with H2S and increase follow the order Pd > Cu > Fe.
