Title:ResearchonthePreparationofActivatedCarbonUsingWasteResinCatalystanditsAdsorptionfortheRemovalofSulfurCompoundsinLiquefiedGas
1.Introduction
Sulfurcompounds,suchashydrogensulfide(H2S)andmercaptans,arecommonlyfoundinliquefiedgasandposesignificantchallengestobothstorageandutilization.Thesecompoundsnotonlyimpartanunpleasantodorbutalsohaveadverseeffectsonhumanhealthandtheenvironment.Therefore,thedevelopmentofefficientandcost-effectivemethodstoremovesulfurcompoundsfromliquefiedgasisofgreatimportance.Inthisstudy,weproposetheuseofwasteresincatalystsforthepreparationofactivatedcarbonandthesubsequentevaluationofitsadsorptionperformancefortheremovalofsulfurcompoundsfromliquefiedgas.
