Kuchotsa Hydrogen Sulfide Ndi Mercaptan

Petrochemicals 3

Kuphatikiza pa hydrogen sulfide, mpweya wosweka wa petroleum nthawi zambiri umakhala ndi kuchuluka kwa sulfure wachilengedwe.Chinsinsi chochepetsera zinthu za sulfure ndikuchotsa bwino kwa sulfure mowa ndi hydrogen sulfide ku gasi yaiwisi.Sieve ya mamolekyulu imatha kugwiritsidwa ntchito kupangira zinthu zina zokhala ndi sulfure.Mfundo ya adsorption imaphatikizapo mbali ziwiri:

1 - kusankha mawonekedwe ndi kutsatsa.Pali njira zambiri zotsekera yunifolomu mu kapangidwe ka molekyulu ya sieve, zomwe sizimangopereka gawo lalikulu lamkati, komanso zimachepetsa kuchuluka kwa mamolekyu okhala ndi polowera chachikulu.

2- polar adsorption, chifukwa cha mawonekedwe a ion lattice, ma molekyulu sieve pamwamba ndi polarity kwambiri, motero ali ndi mphamvu yotsatsa ya ma molekyulu osaturated, mamolekyu a polar ndi mamolekyu opangidwa mosavuta.Sieve ya molekyulu imagwiritsidwa ntchito makamaka kuchotsa thiol ku gasi wachilengedwe.Chifukwa cha polarity yofooka ya COS, yofanana ndi ma cell a COS2, pali mpikisano pakati pa adsorption pa molecular sieve pamaso pa CO2.Kufewetsa ndondomeko ndi kuchepetsa zida ndalama, molecular sieve adsorption sulphate nthawi ntchito limodzi ndi maselo sieve kuchepa madzi m'thupi.

Kubowo kwa JZ-ZMS3, JZ-ZMS4, JZ-ZMS5 ndi JZ-ZMS9 molecular sieve ndi 0.3nm, 0.4nm, 0.5nm ndi 0.9nm.Zinapezeka kuti JZ-ZMS3 sieve ya molekyulu imayamwa thiol, JZ-ZMS4 molecular sieve imatenga mphamvu yaying'ono ndipo JZ-ZMS9 sieve ya molekyulu imatenga thiol mwamphamvu.Zotsatira zikuwonetsa kuti mphamvu ya adsorption ndi katundu wa adsorption amawonjezeka pamene kabowo kamawonjezeka.
