摘要

Abstract

Methane decomposition reaction has been studied at three different activation temperatures (500℃

800℃ and 950℃) over mesoporous alumina supported Ni-Fe and Mn-Fe based bimetallic catalysts. On co-impregnation of Ni on Fe/Al

the activity of the catalyst was retained even at the high activation temperature at 950℃ and up to 180 min. The Ni promotion enhanced the reducibility of Fe/Al

oxides showing higher catalytic activity with a hydrogen yield of 69%. The reactivity of bimetallic Mn and Fe over Al

catalyst decreased at 800℃ and 950℃ activation temperatures. Regeneration studies revealed that the catalyst could be effectively recycled up to 9 times. The addition of O

(1 ml

2 ml

4 ml) in the feed enhanced substantially CH

conversion

the yield of hydrogen and the stability of the catalyst.
