Abstract

The oxidation activity of molecular sieves ion-exchanged by Pd were investigated as a catalyst for the low temperature combustion of CH₄. Among the molecular sieves examined, SAPO-5 ion-exchanged by Pd exhibited the highest activity for CH₄ combustion as well as the high thermal stability. Since the high dispersion of Pd particles was attained with ion-exchanged method, plateau in the temperature dependence of CH₄ conversion was hardly appeared on Pd-HSAPO-5 catalysts in the high space velocity of CH₄. Furthermore, the high activity of Pd-HSAPO-5 was sustained after the precalcination up to 1000°C. Consequently, Pd-HSAPO-5 is a promising combustion catalyst in low temperature range.
