摘要：

Pd/Al2O3　catalyst　supported　on　honeycomb　monolith　was　prepared　and　modified　by　loading　barium,　lanthanum　and　cerium.　Catalytic　combustion　of　natural　gas　was　studied　on　a　premixed　combustor.　The　experimental　results　showed　that　the　temperature　of　flameless　catalytic　combustion　ranges　from　500　to　900°C.　Catalytic　combustion　is　affected　by　velocity　of　flow　and　air/gas　ratio.　It　can　be　carried　out　when　the　air/gas　ratio　ranges　from　8.3　to　19　and　the　best　catalytic　combustion　performance　remains　at　the　air/gas　ratio　between　11　and　19,　with　emission　of　CO　and　HC　less　than　10-5,　and　NOx　less　than　5　×　10-6　in　the　exhaust.
