Ukusekelwa kwe-Catalyst kuyingxenye ekhethekile ye-catalyst eqinile. Kuyi-dispersant, i-binder kanye nokusekelwa kwezingxenye ezisebenzayo ze-catalyst, futhi ngezinye izikhathi kudlala indima ye-Co catalyst noma i-cocatalyst. Ukusekelwa kwe-Catalyst, okwaziwa nangokuthi ukwesekwa, kungenye yezingxenye ze-catalyst esekelwayo. Ngokuvamile kuyinto equkethe imigodi enendawo ethile ethile. Izingxenye ezisebenzayo ze-catalyst zivame ukunamathela kuyo. I-catalyst isetshenziswa kakhulu ukusekela izingxenye ezisebenzayo nokwenza i-catalyst ibe nezakhiwo ezithile zomzimba. Kodwa-ke, i-catalyst ngokwayo ngokuvamile ayinawo umsebenzi we-catalytic.
Izidingo zokusekelwa kwe-catalyst
1. Kunganciphisa ubuningi bezingxenye ezisebenzayo, ikakhulukazi izinsimbi eziyigugu
2. Futhi ingalungiswa ibe yisimo esithile
3. Ukucwilisa phakathi kwezingxenye ezisebenzayo kungavinjelwa ngezinga elithile
4. Ingamelana nobuthi
5. Ingasebenzisana nezingxenye ezisebenzayo futhi isebenze kanye ne-catalyst eyinhloko.
Umphumela wokusekelwa kwe-catalyst
1. Nciphisa izindleko ze-catalyst
2. Thuthukisa amandla okusebenza kwe-catalyst
3. Ukuthuthukisa ukuzinza kokushisa kwama-catalyst
4. Umsebenzi kanye nokukhetha kwe-catalyst eyengeziwe
5. Yandisa impilo ye-catalyst
Isingeniso kubathwali abaningana abayinhloko
1. I-alumina esebenzayo: isithwali esisetshenziswa kakhulu kuma-catalyst ezimboni. Ishibhile, inokumelana nokushisa okuphezulu, futhi inamandla amahle ezingxenyeni ezisebenzayo.
2. Ijeli ye-Silica: ukwakheka kwamakhemikhali yi-SiO2. Ngokuvamile kulungiswa ngengilazi yamanzi efaka i-asidi (Na2SiO3). I-Silicate yakhiwa ngemva kokuba i-sodium silicate isabela ne-asidi; i-Silicic acid iyapholisha futhi ijiye ukuze yakhe ama-polymer anesakhiwo esingaqinisekile.
I-SiO2 iyisithwali esisetshenziswa kabanzi, kodwa ukusetshenziswa kwayo kwezimboni kuncane kunokwe-Al2O3, okubangelwa amaphutha anjengokulungiswa okunzima, ukusondelana okubuthakathaka nezingxenye ezisebenzayo, kanye nokusha kalula ngaphansi kokuba khona komhwamuko wamanzi.
3. Isihlungi sama-molecule: siyi-crystalline silicate noma i-aluminosilicate, okuyisistimu ye-pore kanye ne-cavity eyakhiwe yi-silicon oxygen tetrahedron noma i-aluminium oxygen tetrahedron exhunywe yi-oxygen bridge bond. Inokusimama okuphezulu kokushisa, ukusimama kwamanzi kanye nokumelana ne-asidi ne-alkali
