Title:ExperimentalAnalysisof40kgShenDongCoalCokeOvenPyrolysisandProductAnalysis
Introduction(150words):
Thepyrolysisofcoalinacokeovenisanessentialprocessintheproductionofcoke.Understandingthepyrolysisbehaviorandproductanalysisofcoaliscrucialforoptimizingcokeproductionprocessesandstudyingthepotentialutilizationoftheby-products.Inthisstudy,weconducteda40kgShenDongcoalcokeovenpyrolysisexperimentandanalyzedtheproducedproducts.Theaimwastoinvestigatethethermaldecompositioncharacteristicsofcoalandprovideinsightsintothediverseproductdistributionandcompositionsduringthepyrolysisprocess.
ExperimentalSetupandProcedure(200words):
Theexperimentwasconductedinalaboratory-scalecokeovenwitha40kgcapacity.TheShenDongcoalwasselectedastherawmaterialforpyrolysisduetoitswidespreadusageinthecokeindustry.Thecoalsamplewascrushedtoaspecificparticlesizeandloadedintothecokeoven.Thepyrolysisprocesswascarriedoutundercontrolledtemperatureandheatingrates.Thevolatilematterreleasedduringpyrolysiswascollected,andthesolidresidueproducedwasanalyzedforfixedcarboncontent.Thevolatilematterwasfurtheranalyzedtodeterminethecompositionofgases,tar,andwater.
ResultsandDiscussion(600words):
ThepyrolysisoftheShenDongcoalsampleresultedintheproductionofvariousgas,solid,andliquidproducts.Theanalysisofvolatilematterindicatedthepresenceofhydrogen,carbonmonoxide,methane,andothercombustiblegases.Thegascompositionvariedwithtemperatureandheatingrate,suggestingdifferentreactionpathwaysandcrackingmechanismsofthecarbonaceousmaterialswithinthecoal.Additionally,thecollectedtarexhibitedawiderangeofchemicalcomponents,includingphenols,cresols,andpolycyclicaromatichydrocarbons(PAHs).ThehighconcentrationofPAHsinthetarindicatedthepotentialenvironmentalrisksassociatedwiththeutilizationordisposalofthisby-product.
