Isihluzo semolekyuli se-LSX – Uhlobo lwe-Silica X oluphantsi
Isihluzo semolekyuli se-LSX – Uhlobo lwe-Silica X oluphantsi
Injongo:
■ Ukususa ikharbon diokside: Nokuba kuphantsi kakhulu kuxinzelelo oluncinci, ibonisa amandla abalaseleyo okufunxa ikharbon diokside.
■ Susa umswakama: Yenza inkqubo yokomisa umoya ibe nkulu ukuze kuthintelwe ukubanda nokuvaleka kwezixhobo kwiindawo ezinobushushu obuphantsi. ；
■ Ukususwa kwee-hydrocarbons: Ifunxa ngokufanelekileyo izinto ezinokutsha neziqhumayo ezifana ne-acetylene kunye ne-ethane, iqinisekisa ukhuseleko lwemveliso ；
■ Ukucocwa kwegesi yemizi-mveliso: Isetyenziselwa ukususwa kwesalfure kwigesi yendalo, kunye nokususwa kwesalfure namanzi kwigesi yepetroleum enyibilikisiweyo (LPG), njl.njl.
Uphawu:
Isihluzo semolekyuli seSilica X esiphantsi sikristale esenziwe ngokwenziwa esenziwe nge-silicate-aluminate enomthamo ophezulu kakhulu we-pore kunye nommandla othile womphezulu. Xa kuthelekiswa nezihluzo zemolekyuli eziqhelekileyo ze-13X, siphucula kakhulu amandla okufunxa iimolekyuli ze-polar ngokunciphisa umlinganiselo we-silicon-aluminium (i-SiO2/Al2O3 isondele kwi-2). Kwangaxeshanye, ipropati "yokungabikho kwe-potassium" iqinisekisa uzinzo olungcono lobushushu kunye namandla oomatshini phantsi kweemeko ezithile zenkqubo.
Xa kuthelekiswa nesihluzo se-molecular se-13X esiqhelekileyo, i-13X engena-potassium, ene-silicon ephantsi, inezi nzuzo zilandelayo ezimangalisayo:
Umthamo we-adsorption onamandla kakhulu: Ngenxa yomlinganiselo ophantsi we-silicon-aluminium, inani le-cations ezisebenzayo ezisebenzayo kwiseli yekristale liyanda, kwaye umthamo wayo we-adsorption ye-CO2 uphezulu ngama-20%-40% kunalowo we-13X eqhelekileyo. Ubomi obude bomjikelo: Phantsi komthamo womoya ofanayo, inokwandisa umjikelo wokutshintsha, ngaloo ndlela inciphise ukusetyenziswa kwamandla kwenkqubo yokupholisa umoya kunye nenkqubo yokufudumeza. Ukusebenza kakuhle kwe-kinetic: Isantya se-adsorption siyakhawuleza, kwaye nokuba kumanqanaba aphezulu okuhamba kwegesi (umthamo omkhulu wokucubungula), inokugcina indawo encinci kakhulu yokudlulisa ubunzima. Uzinzo olubalaseleyo lobushushu: Uyilo "olungena-potassium" luphepha iingozi zokucola obushushu obuphezulu okanye ukunciphisa amandla okubangelwa yi-potassium ions kwiimeko ezithile zokusebenza, kwaye lunobomi benkonzo ende (ngesiqhelo ukuya kuthi ga kwiminyaka emi-3-5). Ukonga iindleko kutyalo-mali lwezixhobo: Ngenxa yokusebenza okuphezulu kwe-adsorption, umthamo woyilo lwenqaba ye-adsorption unokuncipha, kwaye iindleko zomgangatho kunye neziseko zenkqubo yonke zinokuncitshiswa.
