Abathwali be-Catalyst badlala indima ebalulekile ekukhiqizeni amakhemikhali. Azithinti kuphela umsebenzi nokuzinza kwama-catalysts, kodwa futhi zihlobene ngokuqondile nokusebenza kahle kokusabela kanye nekhwalithi yomkhiqizo. Ngokukhula kwesidingo sama-catalyst asebenzayo futhi anobungani bemvelo embonini yamakhemikhali yomhlaba wonke, ukukhethwa okufanele kanye nokusetshenziswa kwama-catalyst carriers sekugxilwe kakhulu emabhizinisini. Lesi sihloko sizokwethula ukucatshangelwa okubalulekile ekusetshenzisweni kwama-catalyst carriers ukusiza abahwebi bangaphandle kanye nezinkampani zamakhemikhali ukuthi zibambe kangcono amaphuzu ezobuchwepheshe.
Okokuqala, ukukhethwa kwezinto zokuphatha kudinga ukunqunywa ngokuya ngezimo ezithile zokusabela. Izithwali ezivamile zihlanganisa i-alumina, i-silica, i-carbon activated kanye nezisefo zamangqamuzana, ngayinye enezindawo ezihlukile ezihlukile, izakhiwo ze-pore kanye nokuzinza kwamakhemikhali. Isibonelo, abathwali be-alumina bafanele-ukusabela okuphezulu kwezinga lokushisa, kuyilapho ikhabhoni ecushiwe ifaneleka kakhulu izikhathi ezidinga ukusebenza kwe-adsorption ephezulu. Amabhizinisi adinga ukuhlanganisa izinga lokushisa lokusabela, ingcindezi kanye nezici ezimaphakathi ukuze akhethe uhlobo lwenkampani yenethiwekhi olufana kakhulu ukuze kuqinisekiswe-ukusebenza kwesikhathi eside nokuthembeka kwe-catalyst.
Okwesibili, inqubo yokwelashwa okungaphezulu komthwali ithinta ngqo umphumela wokulayisha we-catalyst. Ngokugeza i-asidi, ukwelashwa kwe-alkali noma ukuguqulwa kwendawo, ukusatshalaliswa kwe-pore kanye nezindawo zamakhemikhali ezingaphezulu zesiphathi kungenziwa ngcono, ngaleyo ndlela kuthuthukiswe ukuhlakazeka kwezingxenye ezisebenzayo. Lapho uthenga ama-catalyst carriers, amabhizinisi ohwebo lwangaphandle kufanele anake ukuthi ingabe umphakeli uhlinzeka ngezinsizakalo zokucubungula ezenziwe ngokwezifiso ukuhlangabezana nezidingo zokusabela okuthile. Ukwengeza, ubumsulwa nokungcola okuqukethwe komthwali kufanele futhi kulawulwe ngokuqinile ukuze kugwenywe ubuthi be-catalyst noma ukonakala kokusebenza ngenxa yokwethulwa kokungcola.
Okokugcina, izimo zokugcina nezokuthutha zibaluleke ngokulinganayo ekusebenzeni kwabathwali be-catalyst. Izinto eziningi zenkampani yenethiwekhi ziyazwela kumswakama, futhi ukuchayeka isikhathi eside-kuzindawo ezinomswakama kungase kubangele ukumuncwa kwamanzi noma izinguquko zesakhiwo. Kunconywa ukuvala inkampani yenethiwekhi endaweni eyomile futhi uthathe izinyathelo zokuvikela umswakama{3} ngesikhathi sokuthutha. Ngebhizinisi lokungenisa nokuthekelisa, kuyadingeka futhi ukunaka izindinganiso zokuthutha zamazwe ngamazwe ukuze uqinisekise ukuthi inkampani yenethiwekhi isengakwazi ukulondoloza ukusebenza kwayo kwasekuqaleni ngemva{5}}kokuhamba ibanga elide.
Ngamafuphi, ukukhethwa kanye nokusetshenziswa kwezithwali ze-catalyst kubandakanya ulwazi emikhakheni eminingi efana nesayensi yezinto zokwakha kanye nobunjiniyela bokusabela kwamakhemikhali. Kuphela ngokuqonda ngokujulile imininingwane efanele yobuchwepheshe lapho amabhizinisi ohwebo angaphandle angakwazi ukunikeza amakhasimende-imikhiqizo namasevisi ekhwalithi ephezulu, ngaleyo ndlela ezuza inzuzo emqhudelwaneni wamazwe ngamazwe oshubile.
