Ukongeza kwi-hydrogen sulfide, i-petroleum cracking gas idla ngokuba nenani elithile le-organic sulfur.Isitshixo sokunciphisa umxholo wesulfure kukususwa okusebenzayo kwe-alcohol sulfure kunye ne-hydrogen sulfide kwi-gas eluhlaza.Isefu yemolekyuli ingasetyenziselwa ukuthengisa iikhompawundi ezinesulfure.Umgaqo we-adsorption ikakhulu ubandakanya imiba emibini:
1- ukukhetha imilo kunye ne-adsorption.Kukho iziteshi ezininzi zokuvula i-uniform kwi-molecular sieve structure, engaboneleli kuphela indawo enkulu yangaphakathi, kodwa iphinde inciphise umlinganiselo weemolekyuli kunye nokungena kwe-aperture enkulu.
I-2- i-adsorption ye-polar, ngenxa yeempawu ze-ion lattice, i-molecular sieve surface yi-polarity ephezulu, ngoko ke inomthamo ophezulu wokubhengeza iimolekyuli ezingaxutywanga, iimolekyuli ze-polar kunye ne-polarized molecules ngokulula.I-molecular sieve isetyenziselwa ukususa i-thiol kwigesi yendalo.Ngenxa ye-polarity ebuthathaka ye-COS, efana nesakhiwo se-molecular CO2, kukho ukhuphiswano phakathi kwe-adsorption kwi-molecular sieve phambi kwe-CO2.Ukwenza lula inkqubo kunye nokunciphisa utyalo-mali lwezixhobo, i-molecular sieve adsorption sulfate idla ngokusetyenziswa ngokubambisana ne-molecular sieve dehydration.
I-aperture ye-JZ-ZMS3, JZ-ZMS4, JZ-ZMS5 kunye ne-JZ-ZMS9 i-molecular sieve yi-0.3nm, 0.4nm, 0.5nm kunye ne-0.9nm.Kwafunyaniswa ukuba i-JZ-ZMS3 i-molecular sieve ayifunxanga i-thiol, i-JZ-ZMS4 i-molecular sieve ifunxa umthamo omncinci kwaye i-JZ-ZMS9 i-molecular sieve ifunxa kakhulu i-thiol.Iziphumo zibonisa ukuba umthamo we-adsorption kunye neempawu ze-adsorption zonyuka njengoko i-aperture isanda.
Iimveliso ezinxulumeneyo:I-JZ-ZMS9 i-molecular sieve; I-JZ-ZHS i-molecular sieve
