I-Alumina ifunyenwe ukuba ikhona ubuncinane i-8 yefom, ziyi-α- Al2O3, θ-Al2O3, γ- Al2O3, δ- Al2O3, η- Al2O3, χ- Al2O3, κ- Al2O3 kunye ne-ρ- Al2O3, iipropati zabo ze-macroscopic ezihlukeneyo nazo zahlukile. I-alumina esebenzayo yeGamma yikhyubhiki evaliweyo epakishwe ngekristale, enganyibilikiyo emanzini, kodwa inyibilika kwiasidi kunye nealkali. I-alumina esebenzayo ye-gamma ibuthathaka kwinkxaso ye-asidi, inendawo ephezulu yokunyibilika eyi-2050 ℃, ijeli ye-alumina ekwimo ye-hydrate inokwenziwa kwi-oxide ene-porosity ephezulu kunye nomphezulu othile ophakamileyo, inezigaba zotshintsho kuluhlu olubanzi lobushushu. Kwiqondo lokushisa eliphezulu, ngenxa yokuphelelwa ngamanzi emzimbeni kunye ne-dehydroxylation, i-Al2O3surface ibonakala ilungelelanisa i-oksijini engaxutywanga (iziko le-alkali) kunye ne-aluminium (iziko le-asidi), kunye nomsebenzi we-catalytic. Ke ngoko, i-alumina ingasetyenziselwa njengomphathi, i-catalyst kunye ne-cocatalyst.I-alumina esebenzayo yeGamma inokuba ngumgubo, iigranules, imicu okanye ezinye. Sinokwenza ngokwemfuno yakho.γ-Al2O3, yayibizwa ngokuba “i-alumina esebenzayo”, luhlobo lwezixhobo eziqinileyo ezisasazekileyo, ngenxa yesakhiwo sayo esilungelelanisiweyo sepore, indawo enkulu ethile yomphezulu, ukusebenza kakuhle kwe-adsorption, umphezulu onezibonelelo zeasidi kunye nokuzinza okuhle kwe-thermal, umphezulu we-microporous kunye neepropati ezifunekayo ze-catalytic action, ngoko ke i-catalyst ye-catalyst isetyenziswa kakhulu umthwali kwimveliso yeekhemikhali kunye ne-oyile, kwaye idlala indima ebalulekileyo kwi-oil hydrocracking, i-hydrogenation refining, i-hydrogenation reforming, i-dehydrogenation reaction kunye nenkqubo yokucoca i-automobile exhaust. Xa i-γ- i-Al2O3 isetyenziswa njengomthwali, ngaphandle kwayo ingaba nemiphumo yokusabalalisa kunye nokuzinzisa amacandelo asebenzayo, inokubonelela ngeziko le-asidi yealkali esebenzayo, i-synergistic reaction kunye ne-catalytic active components. Ubume bepore kunye neepropathi zomphezulu we-catalyst zixhomekeke kwi-γ-Al2O3 carrier, ngoko ke umthwali wokusebenza okuphezulu unokufunyanwa kwimpendulo ethile ye-catalytic ngokulawula iipropathi ze-gamma alumina carrier.I-alumina esebenzayo ye-gamma yenziwa ngokubanzi nge-precursor yayo ye-pseudo-boehmite nge-400 ~ 600 ℃ yokuphelelwa ngubushushu obuphezulu, ngoko ke iipropati ze-physicochemical zomhlaba zimiselwa ubukhulu becala yi-precursor yayo ye-pseudo-boehmite, kodwa kukho iindlela ezininzi zokwenza i-pseudo-boehmite, kunye nemithombo eyahlukeneyo ye-diversityudo ye-Al-boehmite ye-Al-Boehmite ye-Al-Boehmite. Noko ke, kwezo catalysts kunye neemfuno ezikhethekileyo ukuba alumina carrier, bathembele kuphela kulawulo precursor pseudo-boehmite kunzima ukufikelela, kufuneka kuthatyathwe prophase ukulungiselela kunye post processing ukudibanisa iindlela ukulungisa iipropati alumina ukuhlangabezana neemfuno ezahlukeneyo. Xa ubushushu bungaphezulu kwe-1000 ℃ esetyenziswayo, i-alumina yenzeka inguqu yesigaba esilandelayo: γ→δ→θ→α-Al2O3, phakathi kwabo γ、δ、θ yi-cubic yokupakisha esondeleyo, umahluko ulele kuphela kunikezelo lwe-ion ze-aluminium kwi-tetrahedral kunye ne-octahedral, ngoko ke olu tshintsho lwesigaba alubangeli ulwakhiwo oluninzi. Ii-ion zeoksijini kwisigaba se-alpha zi-hexagonal ukupakisha ngokusondeleyo, amasuntswana e-aluminiyam oxide kukudibana kwakhona, indawo ethile yomphezulu inqabile kakhulu.
Ugcino:lKuphephe ukufuma, kunqande ukuskrola, ukujula kunye nokothuka okubukhali ngexesha lokuhamba, izibonelelo zemvula kufuneka zilungiswe.l Kufuneka igcinwe kwindawo eyomileyo nengena umoya ukunqanda ukosuleleka okanye ukufuma.Iphakheji:Uhlobo
