CD I249 1 0013788

In: Summary: Transcripción del abstract original del autor: The selective catalytic reduction of nitrogen oxides (NOx) by methane was investigated to clarify its applicability as a de-NOx catalyst for small GHP and CHP. Durability tests under the conditions of lean-burn gas engine exhaust showed that Fe-doped sulfated zirconia loaded with Pd and Pt has sufficient activity and durability for the NOx reduction by methane in the presence of excess oxygen (10 vol.%), water vapor (9 vol.%) and sulfur dioxide (0.3 vol.ppm). Within the temperature range of 450 to 525ºC, a NOx conversion higher than 60% can be obtained at a GHSV of 15,000 h-1, which is comparable with the typical catalyst volume of ammonia-SCR.
