Hydrotalcite-type 전구체로부터 제조된 Mixed Metal Oxide 촉매의 조성에 따른 N2O 분해 특성 연구
Reaction Properties of N2O Decomposition over Mixed Metal Oxide Catalysts Made from Hydrotalcite-Type Precursors
N2O is Known to have global warming potential 310 times that of CO2 on a per molecule basis, and many studies have been proceeded to remove N2O. The hydrotalcite-type compounds could be obtained by co-precipitation of various bivalent and trivalent cation metals. The reaction were carried out under atmospheric pressure in the temperature range 250 - 500 ℃ with the catalysts made from the hydrotalcite-type precursors by calcining at 500 ℃. Catalytic decomposition of N2O over thermally calcined hydrotalcites of mixed metals was proven very efficient for space volume around 30,00/hr and temperature under 500 ℃. The experiments were performed to study the reaction behaviour of N2O decomposition over mixed metal oxide catalysts made from hydrotalcite-type precursors in the low temperature range.
