The　Fe-Ni　alloy　metal　(70%Fe-30%Ni)　foams　were　used　as　a　base　material　for　the　catalyst　support,　and　the　metal　foam　based　monolithic　catalysts　(Pd/Al2O3/Fe-Ni)　were　prepared　by　wet　impregnation.　Then　experimental　study　the　catalytic　combustion　of　low　concentration　methane　in　micro-combustor　over　metal　foam　monolithic　catalyst.　It　analyzed　the　influences　of　reactor　temperature,　CH4　concentration　and　flow　rate　on　methane　conversion　rate.　The　results　showed　that　conversion　rate　increased　with　the　increase　of　reactor　temperature　and　the　decrease　of　mixture　flow　rate　and　the　increase　of　CH4　concentration.　Further　analysis　showed　that　the　temperature　is　the　key　factors　for　CH4　conversion.　When　the　reactor　temperature　is　550,　CH4　concentration　is　5%,　mixture　flow　rate　is　950　K,　the　conversion　rate　of　CH4　can　achieve　to　98.7%.　©,　2015,　Chemical　Industry　Press.　All　right　reserved.
