Kuthiwani ngokusebenza kwe-adsorption kwe-4A molecular sieve ye-H₂S?Ukuze kuxazululwe inkinga yokungcoliswa kwephunga le-H₂S ezindaweni zokulahla imfucumfucu, Sikhetha i-ganggue yamalahle eluhlaza ne-kaolin eshibhile eshibhile, kwenziwa isisefo se-molecular 4A nge-adsorption enhle kanye nomthelela we-catalytic ngokusebenzisa indlela ye-hydrothermal.Ukuhlolwa kuhlole ikakhulukazi umthelela wezinga lokushisa lokubala elihlukile nesikhathi sokucwebezela ekusebenzeni kwe-adsorption desulfurization.
Imiphumela ikhombisa ukuthi ukusebenza kwe-adsorption desulfurization kwe-4A molecular sieve elungiswe i-kaolin ngokusobala ingcono kune-coal gangue.Izinga lokushisa lokubala lingu-900 ℃, izinga lokushisa lecrystallization liyi-100 ℃, isikhathi secrystallization ngu-7h, kanti isilinganiso sezinto ezibonakalayo noketshezi ngu-1:7.Uma ukugxila kwe-alkali kungu-3mol/L, umthamo we-desulfurization ungafinyelela ku-95mg/g.Ukuhlaziywa kwe-X-ray diffraction kubonise ukuthi kwakukhona iziqongo ezisobala zesici sesibabule esibonakalayo ngemva kokukhangisa nge-4A yesisefo samangqamuzana, okubonisa ukuthi umkhiqizo we-4A wokufakwa kwe-molecular sieve ye-H 2 S igesi ephunga kwakuyi-elemental sulphur.
Isisefo se-molecular 4A ku-press swing adsorption kulula ukungeniswa ushevu futhi silahlekelwe umsebenzi wawo, okubangela ukuthi yonke into esetshenziswayo ime ukusebenza.Izisefo zamangqamuzana zenza ingxenye enkulu yezindleko ze-PSA, futhi ukonga kwezindleko zesethi ephelele yesisefo se-molecular PSA imishini yokucebisa umoya-mpilo cishe ilingana nezindleko zokonga amandla.Ekusetshenzisweni okungokoqobo, i-press swing adsorption ubuchwepheshe obuthuthukisiwe, kodwa okokusebenza kuyabiza, isisefo samangqamuzana sinokuphila okufushane kwesevisi, futhi okokusebenza okukhiqiziwe, Intengo ilingana nokugcinwa kwenzuzo, okwenza umfutho we-molecular sieve swing adsorption ungavamile uma usetshenziswa.
Ama-molecule e-carbon akhiqiza i-nitrogen we-4A molecular sieve pressure swing adsorption adsorption kalula atheleleka ngama-molecule amanzi, amagesi abolayo, amagesi e-asidi, uthuli, ama-molecule kawoyela, njll., okuholela ekungasebenzini kwamangqamuzana.Okuningi kwalokhu kungasebenzi akubuyiseleki emuva.Ukuphinda kusebenze kungenziwa ngokushaywa umoya namanzi ahlanzekile uma kuthanda, kodwa ngisho nama-molecule ekhabhoni aphinde asebenza avame ukungasabeli futhi akhiqize i-nitrogen kuneyasekuqaleni, okuyilokho esikubiza ngokuthi ubuthi besisefo samangqamuzana.
