Ihe kpatara molekụla sieve inactivation na usoro nchacha nke ikuku nkewa

1, mmetụta nke oke ọdịnaya mmiri na ọrụ sieve molecular
Ọrụ bụ isi nke ihe nkewa nke ikuku ikuku bụ iwepụ mmiri na ọdịnaya hydrocarbon site na ikuku iji nye ikuku akọrọ maka usoro ndị na-esote. Ihe owuwu akụrụngwa dị n'ụdị akwa akwa kwụ ọtọ, ala arụ ọrụ alumina dị elu bụ 590 mm, elu 13X molecular sieve na-ejuputa dị elu bụ 962 mm, a na-agbanwekwa ihe abụọ ahụ n'etiti ibe ha. N'ime ha, alumina arụ ọrụ tumadi adsorbs mmiri na ikuku, na molekụla sieve na-eji ya molekụla nhọrọ adsorption ụkpụrụ adsorb hydrocarbons. Dabere na ihe mejupụtara ihe mejupụtara ya na akụrụngwa mgbasa ozi nke sieve molecular, usoro mgbasa ozi bụ: H2O> H2S> NH3> SO2> CO2 (usoro mgbasa ozi nke gas alkaline). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4 (usoro nke adsorption nke hydrocarbons). Enwere ike ịhụ na ọ nwere arụmọrụ adsorption kachasị ike maka ụmụ irighiri mmiri. Otú ọ dị, ihe dị n'ime mmiri nke sieve molecular dị oke elu, na mmiri efu ga-eme ka mmiri kristal na sieve molecular. Okpomọkụ (220 Celsius C) nke 2.5MPa na-enye uzuoku nke eji eme ka okpomọkụ dị elu ka na-enweghị ike iwepụ akụkụ a nke mmiri kristal, na pore size nke molekul sieve na-eji kristal mmiri molekul, n'ihi ya, ọ pụghị ịnọgide na-adsorb hydrocarbons. N'ihi ya, a na-eme ka ọkpụkpụ molekụla kwụsị, ndụ ọrụ na-adị mkpụmkpụ, na mmiri mmiri na-abanye n'ime obere efere okpomọkụ nke usoro nhazi nhazi, na-eme ka ọwa mmiri na-asọba nke ikpo ọkụ na-ekpo ọkụ na ngọngọ, na-emetụta ọwa ikuku ikuku na mmetụta na-enye okpomọkụ nke onye na-ekpo ọkụ ọkụ, na n'ọnọdụ ndị siri ike, ngwaọrụ ahụ enweghị ike ịrụ ọrụ nke ọma.
2. Mmetụta nke H2S na SO2 na ọrụ sieve molecular
N'ihi mgbasa ozi ahọpụtara nke sieve molecular, na mgbakwunye na mgbasa ozi dị elu nke mkpụrụ ndụ mmiri, njikọ ya maka H2S na SO2 dịkwa mma karịa arụmọrụ mgbasa ozi ya maka CO2. H2S na SO2 na-anọ n'elu arụ ọrụ nke sieve molecular, na akụkụ acidic na-emeghachi omume na sieve molecular, nke ga-eme ka sieve molecular merụọ ma mebie ya, ikike mgbasa ozi nke sieve molecular ga-ebelata. A na-ebelata ndụ ọrụ nke sieve molecular.
Na nchịkọta, oke mmiri ọdịnaya, H2S na SO2 gas ọdịnaya na ntinye ikuku nke ikuku nkewa ikuku jụrụ ụlọ elu bụ isi ihe mere inactivation nke molekụla sieve na shortening nke ọrụ ndụ. Site na njikwa siri ike nke ndị na-egosi usoro, mgbakwunye nke onye na-enyocha mmiri mmiri dị ọcha, nhọrọ ezi uche dị na ya nke ụdị fungicides, usoro nhazi oge nke fungicides, ụlọ elu jụrụ oyi iji gbakwunye mmiri raw, nyocha oge niile nke ịgba mmiri na-ekpo ọkụ na ihe ndị ọzọ, ọrụ nchekwa na kwụsiri ike nke purifier nwere ike rụọ nchọpụta oge, ịdọ aka ná ntị n'oge, ngbanwe n'oge, iji hụ na ojiji siri ike ruo ogologo oge.
