Ukusekelwa kwe-Catalyst kuyingxenye ekhethekile ye-catalyst eqinile. I-disperstant, binder kanye nokusekelwa kwezingxenye ezisebenzayo ze-catalyst, futhi ngezinye izikhathi idlala indima ye-Co catalyst noma i-cocatalyst. Ukwesekwa kwe-Catalyst, okwaziwa nangokuthi ukwesekwa, kungenye yezingxenye ze-catalyst esekelwe. Imvamisa iyimpahla enezimbotshana enendawo ethile ethile. Izingxenye ezisebenzayo ze-catalyst zivame ukunamathela kuyo. Isithwali sisetshenziswa ngokuyinhloko ukusekela izingxenye ezisebenzayo futhi senze i-catalyst ibe nezakhiwo ezithile zomzimba. Kodwa-ke, inkampani yenethiwekhi ngokwayo ayinawo umsebenzi we-catalytic.
Izidingo zosekelo lwe-catalyst
1. Inganciphisa ukuminyana kwezingxenye ezisebenzayo, ikakhulukazi izinsimbi eziyigugu
2. Futhi ingalungiswa ibe yisimo esithile
3. Ukungena phakathi kwezingxenye ezisebenzayo kungavinjelwa ngezinga elithile
4. Ingamelana nobuthi
5. Ingakwazi ukusebenzisana nezingxenye ezisebenzayo futhi isebenze kanye ne-catalyst eyinhloko.
Umthelela wosekelo lwe-catalyst
1. Yehlisa izindleko ze-catalyst
2. Thuthukisa amandla omshini we-catalyst
3. Ukuthuthukisa ukuzinza okushisayo kwama-catalysts
4. Umsebenzi kanye nokukhetha kwe-catalyst eyengeziwe
5. Nweba impilo ye-catalyst
Isingeniso kubathwali abaningana abayinhloko
1. I-alumina ecushiwe: inkampani yenethiwekhi esetshenziswa kakhulu kuma-catalysts embonini. Ishibhile, inokumelana nokushisa okuphezulu, futhi inokuhlobana okuhle kwezingxenye ezisebenzayo.
2. Ijeli ye-silica: ukwakheka kwamakhemikhali yi-SiO2. Ngokuvamile ilungiswa ngengilazi yamanzi e-acidifying (Na2SiO3). I-silicate yakheka ngemva kokuba i-sodium silicate isabela nge-asidi; I-Silicic acid iyapholisa futhi iyajiya ukuze yakhe ama-polymer anesakhiwo esingaqinisekile.
I-SiO2 iyinkampani yenethiwekhi esetshenziswa kakhulu, kodwa ukusetshenziswa kwayo kwezimboni kungaphansi kwalokho kwe-Al2O3, okubangelwa iziphambeko ezifana nokulungiselela okunzima, ukusondelana okubuthakathaka nezingxenye ezisebenzayo, nokucwilisa kalula ngaphansi kokuhlangana komhwamuko wamanzi.
3. Isisefo se-molecular: i-crystalline silicate noma i-aluminosilicate, okuwuhlelo lwezimbotshana nezimbotshana olwakhiwe nge-silicon oxygen tetrahedron noma i-aluminium oxygen tetrahedron exhunywe ibhondi yebhuloho le-oxygen. Inokuqina kokushisa okuphezulu, ukuzinza kwe-hydrothermal kanye nokumelana ne-asidi ne-alkali
