Ama-Catalyst Asekelwe I-Alumina: Umdlali Obalulekile Embonini Yamakhemikhali
Ama-catalyst asekelwa yi-alumina adlala indima ebalulekile ezinqubweni ezihlukahlukene zamakhemikhali, okuwenza abe ingxenye ebalulekile embonini yamakhemikhali. Lawa ma-catalysts asetshenziswa kakhulu ekusetshenzisweni kwe-petrochemical, kwezemithi, nakwezemvelo, ngenxa yezakhiwo zawo eziyingqayizivele kanye nokuhlukahluka. Kulesi sihloko, sizocubungula ukubaluleka kwama-catalyst asekelwa yi-alumina, izinhlelo zokusebenza, kanye nezici ezithonya amanani azo, ikakhulukazi esigxile enanini le-gamma alumina, ibhola le-aluminium oxide, kanye ne-alumina catalyst evuliwe.
Ama-catalyst asekelwa i-alumina angama-catalyst lapho ingxenye esebenzayo ye-catalytic ihlakazwa endaweni yokwesekwa kwe-alumina ephezulu. Ukusetshenziswa kwe-alumina njengento yokusekela kunikeza izinzuzo ezimbalwa, okuhlanganisa indawo ephezulu, ukuzinza okushisayo, nokumelana nezindawo zamakhemikhali ezinokhahlo. Lawa ma-catalyst asetshenziswa kakhulu ezinqubweni ezifana ne-hydrocracking, i-hydrotreating, kanye ne-catalytic reforming embonini yokuhluza i-petroleum. Ukwengeza, baqashwe ekukhiqizeni amakhemikhali ahlukahlukene, okuhlanganisa ama-polymers, amapulasitiki, kanye nama-intermediate emithi.
Enye yezingxenye eziyinhloko zama-catalyst asekelwa i-alumina yi-gamma alumina, okuwuhlobo oluyikristalu lwe-alumina eyaziwa ngendawo yayo ephezulu kanye ne-porosity. Intengo ye-gamma alumina iyisici esibalulekile ezindlekweni eziphelele zama-catalyst asekelwa i-alumina. Intengo ye-gamma alumina ithonywa yizinto ezimbalwa, okuhlanganisa izindleko zezinto ezingavuthiwe, izintengo zamandla, kanye nesidingo semakethe. Ukwengeza, ikhwalithi nokuhlanzeka kwe-gamma alumina kuphinde kube nomthelela enanini layo, njengoba amamaki aphezulu abiza iprimiyamu emakethe.
Enye ingxenye ebalulekile ehlobene nama-catalyst asekelwa yi-alumina yibhola le-aluminium oxide. Lawa mabhola asetshenziswa njengezinto zokusekela ama-catalysts, ahlinzeka indawo ezinzile futhi engasebenzi yezingxenye ezisebenzayo ze-catalytic. Intengo yamabhola e-aluminium oxide ithonywa yizici ezifana nezindleko zokukhiqiza, isidingo semakethe, kanye nokutholakala kwezinto ezingavuthiwe. Ubukhulu kanye nokuma kwamabhola nakho kudlala indima ekunqumeni inani lazo, njengoba amabhola amancane nafanayo ngokuvamile ebiza kakhulu ngenxa yokunemba okudingekayo ekukhiqizeni kwawo.
I-alumina catalyst ecushiwe ingenye into ebalulekile endaweni yama-catalyst asekelwa yi-alumina. I-alumina ecushiwe iwumsebenzi onezimbobo kakhulu owaziwa ngokukhangiswa kwawo kanye nezakhiwo zayo ze-catalytic. Isetshenziswa kabanzi njenge-catalyst kanye nesithwali sokuphendula kwamakhemikhali okuhlukahlukene, okubandakanya ukuhlanzwa kwamagesi noketshezi. Intengo ye-alumina catalyst ecushiwe ithonywa izici ezifana nezinga lokuqalisa, indawo engaphezulu, kanye nevolumu yembotshana. Amazinga aphezulu okwenza kusebenze kanye nezindawo ezinkulu ezingaphezulu zibiza amanani aphezulu ngenxa yokwenyuka komsebenzi we-catalytic namandla okukhangisa.
Ukuguquguquka kwama-catalyst asekelwa yi-alumina kudlulela ekusetshenzisweni kwawo njengabathwali be-catalyst ezinqubweni zamakhemikhali ezahlukahlukene. Ukukhethwa komthwali we-catalyst kubalulekile ekunqumeni ukusebenza nokusebenza kahle kwesistimu ye-catalyst. Ama-catalyst asekelwa yi-alumina anikeza amandla amahle kakhulu okusebenza, ukuzinza okushisayo, nokumelana nobuthi, okuwenza abe yinketho ekahle ezinhlobonhlobo zezinhlelo zokusebenza ze-catalytic. Intengo yama-catalyst asekelwe e-alumina njengabathwali ithonywa izici ezifana nendawo ethile, ukusatshalaliswa kosayizi wezimbotshana, kanye nendlela yokulungisa.
Sengiphetha, ama-catalyst asekelwa yi-alumina abalulekile embonini yamakhemikhali, adlala indima ebalulekile ezinqubweni eziningi zamakhemikhali. Amanani alawa ma-catalyst athonywa yizinto ezahlukahlukene, okubandakanya izindleko zezinto ezingavuthiwe, amanani amandla, isidingo semakethe, kanye nezakhiwo ezithile zezingxenye ze-catalyst ezifana ne-gamma alumina, amabhola e-aluminium oxide, ne-alumina ecushiwe. Njengoba isidingo sezinqubo zamakhemikhali ezisebenza kahle nezisimeme sikhula, ama-catalyst asekelwa i-alumina akulungele ukuhlala ebambe iqhaza elibalulekile ekuqhubekiseni ukuqamba okusha kanye nenqubekelaphambili embonini yamakhemikhali.
