Molecular Sieve yog qhov zoo tshaj plaws rau Sulfide Tshem Tawm
Molecular sievezeolite muaj kev xaiv adsorption effect. Nws muaj cov qauv honeycomb. Qhov hws hauv cov kua siv lead ua tau cuam tshuam nrog lwm. Qhov ntim ntawm lub qhov hws tso nyiaj rau ntau dua 50% ntawm qhov ntim ntawm cov zeolite siv lead ua, thiab qhov pore loj yog qhov ncaj ncaj, uas yog sib npaug nrog qhov loj me ntawm molecules. Cov kab xev ntawm cov kab sib xyaw molecular feem ntau yog nruab nrab ntawm 6 thiab 15A; thiab pore loj yog nruab nrab ntawm 3 txog 10A; Tsuas yog cov lwg me me uas muaj qhov ntev me me tuaj yeem raug tsim los ntawm cov suab sib molecular los ntawm lub qhov pores ntawm zeolite, thaum cov lwg me me nrog qhov kev teeb tsa loj tsis tuaj yeem raug adsorbed los ntawm cov suab sib molecular vim tias lawv tsis tuaj yeem nkag mus rau hauv lub qhov pores ntawm zeolite. Silica zeolite muaj qhov txiaj ntsig zoo rau cov ncov qaumteb qabteb thiab cov tsis muaj lub zog, thiab muaj qhov kev tshaj tawm zoo tshaj plaws nyob rau hauv cov kev mob hnyav heev xws li tsis tshua muaj qhov siab, tsis tshua muaj siab, thiab siab kub.
Molecular sieveadsorbents tau dav siv los tshem tawm hydrogen sulfide los ntawm cov roj cua. Thaum ntxov li xyoo 1958, Linde chav haujlwm ntawm United Carbide Corporation tau pib khaws cov ntaub ntawv ntawm kev tshem tawm cov mercaptans thiab lwm cov impurities los ntawm cov nkev. Alkali hlau aluminosilicates tuaj yeem siv los xaiv kev tshem tawm hydrogen sulfide thiab lwm cov sulfide los ntawm cov roj ntuj. Cov adsorption xaiv qhov tsis haum ntawm cov roj molecular saws rau cov ncov qaumteb qabteb tsim lub peev xwm loj rau cov sulfides, thiab cov ntsiab lus sulfur ntawm cov roj av tom qab kev kho mob poob qis dua 0.4ppm (0.53mg / m3). Kev tsim kho cov suab sib molecular siv ncu ntawm 200 txog 300 ° C (lub suab sib molecular yog ruaj khov ntawm 550 ° C lossis siab dua), cov kev tsim dua tshiab tiav thiab lub neej ntev.
Chemxin muaj qhov tshwj xeebMolecular sieverau sulfide tshem tawm nrog efficiency siab. Peb tuaj yeem pab koj kuaj hauv koj lub cuab yeej thiab muab cov kev xaiv zoo tshaj plaws raws li koj tes num. Thov xa ntawv xa rau peb kom paub meej ntxiv.
