Ukonelwa kotywala kwiNqaba yeDistillation/Desiccant/Adsorbent/Hollow glass molecular sieve

Inkcazelo emfutshane:

I-molecular sieve 3A, ekwabizwa ngokuba yi-molecular sieve KA, ene-aperture emalunga ne-3 angstroms, ingasetyenziselwa ukomisa iigesi kunye nolwelo kunye nokuphelelwa ngamanzi emzimbeni kwee-hydrocarbons. Ikwasetyenziswa ngokubanzi ukomisa petroli, iigesi eziqhekekileyo, i-ethylene, ipropylene kunye neegesi zendalo.

Umgaqo osebenzayo we-molecular sieves unxulumene ikakhulu nobukhulu bepore yeesefu ze-molecular, eziyi-0.3nm/0.4nm/0.5nm ngokulandelelanayo. Ziyakwazi ukubhengeza iimolekyuli zerhasi ezinobubanzi bemolekyuli buncinci kunobukhulu bepore. Ubukhulu besayizi yepore, ubukhulu be-adsorption umthamo. Ubungakanani bepore bahlukile, kwaye izinto ezihluzwayo kwaye zahlulwe nazo zahlukile. Ngamagama alula, i-3a ye-molecular sieve inokubhengeza kuphela iimolekyuli ezingaphantsi kwe-0.3nm, i-4a ye-molecular sieve, ii-molecule ze-adsorbed kufuneka zibe ngaphantsi kwe-0.4nm, kunye ne-5a ye-molecular sieve iyafana. Xa isetyenziswe njenge-desiccant, i-molecular sieve inokuthatha ukuya kwi-22% yobunzima bayo kumswakama.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-Zeolite i-molecular sieves inesakhiwo esikhethekileyo sekristale esiqhelekileyo, ngasinye sinesakhiwo se-pore sobukhulu obuthile kunye nokuma, kwaye sinommandla omkhulu ocacileyo. Uninzi lwe-zeolite i-molecular sieves inamaziko e-asidi eqinile kumphezulu, kwaye kukho intsimi ye-Coulomb eqinile kwi-crystal pores ye-polarization. Ezi mpawu ziyenza ibe yi-catalyst egqwesileyo. Iimpendulo ze-Heterogeneous catalytics zenziwa kwii-catalysts eziqinileyo, kwaye umsebenzi we-catalytic unxulumene nobukhulu be-crystal pores ye-catalyst. Xa i-zeolite ye-molecular sieve isetyenziswe njenge-catalyst okanye i-catalyst carrier, inkqubela phambili ye-catalytic reaction ilawulwa yi-pore ye-zeolite ye-molecular sieve. Ubungakanani kunye nokuma kwe-crystal pores kunye ne-pores inokudlala indima ekhethiweyo kwi-catalytic reaction. Phantsi kweemeko zokusabela ngokubanzi, iisefu zemolekyuli ze-zeolite zidlala indima ephambili kwicala lokusabela kwaye zibonisa ukusebenza kwe-catalytic yokukhetha imilo. Lo msebenzi wenza ukuba i-zeolite i-molecular sieves ibe yinto entsha ye-catalytic enamandla anamandla.
