Title:PreparationandDesulfurizationPerformanceStudyofConvolutedStickBentoniteClayBasedDesulfurizingAgentatRoomTemperature
Introduction:
Sulfurdioxide(SO2)emissionsfromvariousindustrialprocessesandpowergenerationhavebeenamajorenvironmentalconcernduetoitsadverseeffectsonhumanhealthandtheenvironment.DesulfurizationtechnologyplaysacrucialroleinreducingSO2emissions.Thedevelopmentofefficient,cost-effective,andenvironmentallyfriendlydesulfurizingagentshasbecomearesearchfocusinrecentyears.Thisstudyaimstoinvestigatethepreparationanddesulfurizationperformanceofaconvolutedstickbentoniteclay-baseddesulfurizingagentatroomtemperature.
MaterialsandMethods:
1.Materials:
-Bentoniteclay
-Sulfur-containingcompound(e.g.,hydrogensulfide,sulfurdioxide)
2.PreparationofConvolutionStickBentoniteClay:
-Bentoniteclayiscollectedandprocessedtoremoveimpurities.
