Title:StudyonMethane-CarbonDioxideReformingReactionoverNi-CaO-ZrO2Catalyst

Introduction:

Theutilizationofmethaneasacleanenergysourcehasdrawnincreasingattentionduetoitsabundantreservesandlowcarboncontent.Meanwhile,carbondioxideisamajorgreenhousegascontributingtoclimatechange.Thereformingofmethaneandcarbondioxidehasbeenconsideredasapromisingwaytoproducesyngas,whichcanbefurtherconvertedintofuelsandvaluablechemicals.Inthisregard,thedevelopmentandoptimizationofcatalystsformethane-carbondioxidereformingiscrucial.

Objectives:

ThisstudyaimstoinvestigatetheperformanceofNi-CaO-ZrO2catalystinmethane-carbondioxidereformingreaction.Morespecifically,theobjectivesare:

1.SynthesizeandcharacterizeNi-CaO-ZrO2catalystswithvaryingcompositions.

2.Evaluatethecatalyticactivity,selectivity,andstabilityofNi-CaO-ZrO2catalystsinmethane-carbondioxidereformingreactionundervariousreactionconditions.

3.Investigatetheeffectofcatalystcomposition,reactiontemperature,H2O/CO2ratio,andspacevelocityonthereactionperformance.

Methodology:

1.Catalystsynthesis:Ni-CaO-ZrO2catalystswillbesynthesizedusingaco-precipitationmethod.Thecatalystswillthenbecalcined,andcharacterizedbyXRD,BET,TEM,andTPRtechniquestodeterminetheirphysicalandchemicalproperties.

2.Catalyticperformanceevaluation:Methane-carbondioxidereformingreactionwillbecarriedoutinafixed-bedreactorusingthesynthesizedcatalysts.Thereactionconditionswillbevariedtostudytheeffectofdifferentparameters.TheproductsofthereactionwillbeanalyzedbyGCtodeterminetheircompositionandselectivity.

3.Mechanisminvestigation:Thereactionmechanismwillbestudiedbyperformingisotopictracingexperimentsbyintroducing13ClabeledmethaneandCO2.
