Nanga bwanji kutsatsa kwa 4A molecular sieve ya H₂S?Pofuna kuthetsa vuto la kuipitsidwa kwa fungo la H₂S m'malo otayirako, Timasankha gangue ya malasha yaiwisi yotsika mtengo ndi kaolin, yomwe inapangidwa ndi 4A molecular sieve yokhala ndi adsorption yabwino komanso chothandizira pogwiritsa ntchito njira ya hydrothermal.The kuyesera makamaka anaphunzira zotsatira zosiyana calcination kutentha ndi crystallization nthawi pa adsorption desulfurization ntchito.
Zotsatira zikuwonetsa kuti adsorption desulfurization performance ya 4A molecular sieve yokonzedwa ndi kaolin mwachiwonekere ndiyabwino kuposa ya malasha gangue.Kutentha kwa calcination ndi 900 ℃, kutentha kwa crystallization ndi 100 ℃, nthawi ya crystallization ndi 7h, ndipo chiŵerengero cha zinthu ndi madzi ndi 1: 7.Pamene ndende ya alkali ndi 3mol/L, mphamvu ya desulfurization imatha kufika 95mg/g.X-ray diffraction kusanthula kunasonyeza kuti panali zodziwikiratu elemental sulfure khalidwe nsonga mu sipekitiramu pambuyo adsorption ndi 4A molecular sieve, kusonyeza kuti mankhwala 4A molecular sieve adsorption wa H2 S odorous mpweya anali elemental sulfure.
The 4A molecular sieve mu pressure swing adsorption ndiyosavuta kupha poizoni ndikutaya ntchito yake, kupangitsa zida zonse kusiya kugwira ntchito.Ma molekyulu a sieve amawerengera gawo lalikulu la mtengo wa PSA, ndipo ndalama zopulumutsira seti yathunthu ya zida zowonjezeretsa mpweya wa PSA ndizofanana ndi mtengo wopulumutsa mphamvu.Mu ntchito zothandiza, kuthamanga pachimake adsorption ndi luso patsogolo, koma zipangizo ndi okwera mtengo, ndi sieve maselo ali ndi moyo waufupi utumiki, ndi zipangizo chopangidwa, Price amafanana phindu ndalama, zomwe zimapangitsa maselo sieve kuthamanga kugwedezeka adsorption osowa mu ntchito zothandiza.
Ma molekyulu a kaboni opangidwa ndi nayitrogeni a 4A molekyulu ya sieve pressure swing adsorption zida amatha kutenga kachilomboka mosavuta ndi mamolekyu amadzi, mipweya yowononga, mipweya ya asidi, fumbi, mamolekyu amafuta, ndi zina zambiri, zomwe zimapangitsa kuti ma molekyulu asagwire ntchito.Zambiri mwazomwezi sizingasinthe.Kuyatsanso kutha kuchitidwa mwa kutulutsa mpweya wabwino ndi madzi ngati mukufuna, koma ngakhale mamolekyu a kaboni omwe adayatsidwanso amakhala osachitapo kanthu komanso kupanga nayitrogeni kuposa choyambirira, chomwe timachitcha kuti chiphe cha molekyulu ya sieve.
