Kuthekani ngokusebenza kwe-adsorption ye-4A ye-molecular sieve ye-H₂S?Ukuze kulungiswe ingxaki ye-H₂S yokungcola kwevumba kwiindawo zokulahla inkunkuma, Sikhetha i-ganggue yamalahle eluhlaza kunye ne-kaolin ephantsi kwexabiso eliphantsi, yenziwe i-4A ye-molecular sieve kunye ne-adsorption enhle kunye ne-catalytic effect ngokusebenzisa indlela ye-hydrothermal.Uvavanyo ikakhulu lufunde isiphumo sobushushu obahlukileyo becalcination kunye nexesha lecrystallization kwi-adsorption desulfurization performance.
Iziphumo zibonisa ukuba ukusebenza kwe-adsorption desulfurization ye-4A ye-molecular sieve elungiswe yi-kaolin ngokucacileyo ingcono kune-gangue yamalahle.Ubushushu be-calcination yi-900 ℃, i-crystallization ye-crystallization yi-100 ℃, ixesha le-crystallization yi-7h, kwaye umlinganiselo wezinto eziphathekayo kwi-liquid yi-1: 7.Xa i-alkali concentration yi-3mol / L, umthamo we-desulfurization unokufikelela kwi-95mg / g.Uhlalutyo lwe-X-ray diffraction lubonise ukuba kukho iincopho ezibonakalayo zesulfure ezicacileyo kwi-spectrum emva kokubhengezwa yi-4A ye-molecular sieve, ebonisa ukuba imveliso ye-4A ye-molecular sieve adsorption ye-H 2 S igesi enukayo yayiyi-elemental sulphur.
I-4A ye-molecular sieve kwi-pressure swing adsorption kulula ukuba ityhefu kwaye ilahlekelwe ngumsebenzi wayo, ibangela ukuba zonke izixhobo ziyeke ukusebenza.I-molecular sieves ichaza umlinganiselo omkhulu weendleko ze-PSA, kunye nokugcinwa kweendleko zeseti epheleleyo ye-molecular sieve izixhobo zokuphucula i-oksijini ye-PSA iphantse ilingane neendleko zokulondoloza amandla.Kwizicelo ezisebenzayo, i-adsorption ye-pressure swing bubuchwepheshe obuphambili, kodwa isixhobo siyabiza, isihluzo semolekyuli sinobomi obufutshane benkonzo, kunye nezixhobo ezenziweyo, Ixabiso lilingana nokugcinwa kwengeniso, nto leyo eyenza i-molecular sieve pressure swing adsorption inqabile kwizicelo ezisebenzayo.
Iimolekyuli zekhabhoni ezivelisa initrogen ye-4A ye-molecular sieve pressure swing adsorption izixhobo zosulelwa lula ziimolekyuli zamanzi, iigesi ezidliwayo, iigesi ze-asidi, uthuli, iimolekyuli zeoyile, njl., okubangela ukungasebenzi kwemolekyuli.Uninzi lolu kungasebenzi alunakuguqulwa.Ukuphinda kusebenze kunokwenziwa ngokugungxulwa ngomoya omtsha kunye namanzi ukuba kuyanqweneleka, kodwa iimolekyuli zekhabhoni eziphinde zaphinda zaphinda zasebenza zidla ngokusebenza kancinci kwaye zivelise initrogen kuneyokuqala, nto leyo esiyibiza ngokuba yityhefu ye-molecular sieve.
