Kwintsimi yoshishino lweekhemikhali zanamhlanje kunye nobuchwepheshe bokukhuselwa kwendalo, abathwali be-catalyst zizinto ezisisiseko ezixhasayo zokuphendula kweekhemikhali, kwaye ukusebenza kwabo kuchaphazela ngokuthe ngqo ukusebenza kwemveliso kunye nezinga lokuthotyelwa kokusingqongileyo. Nangona kunjalo, iinkampani ezininzi azinikeli ngqalelo eyaneleyo kumjikelo wolondolozo lwabathwali, okukhokelela kubomi obufutshane be-catalyst kunye nokwanda kweendleko zokutshintsha. Eli nqaku liza kuphonononga nzulu umjikelo wolondolozo lwabathwali be-catalyst kunye neendlela zabo zolawulo lwezenzululwazi.
Umjikelo wolondolozo lwabathwali be-catalyst ngokuqhelekileyo kuxhomekeke kwizinto zabo, ukusetyenziswa kwendawo kunye neemeko zenkqubo. Ukuthatha i-ceramic kunye nabathwali besinyithi njengemizekelo, abathwali be-ceramic baxhomekeke kwi-carbon deposition ngenxa yesakhiwo sabo esincinci, kwaye kucetyiswa ukuba benze ukucoca okunzulu rhoqo kwiinyanga ezi-6-12; abathwali bentsimbi banokumelana nokugqwala okuqinileyo, kwaye umjikelo wolondolozo unokwandiswa ukuya kwiminyaka eyi-1-2. Nangona kunjalo, le datha yenzelwe ireferensi kuphela, kwaye umjikelo wangempela kufuneka uhlengahlengiswe ngokweemeko ezithile zokusebenza.
Izinto eziphambili ezichaphazela umjikelezo wokugcinwa zibandakanya ukushisa, uxinzelelo, ukugxilwa kwe-reactant kunye nomxholo wokungcola. Ukushisa okuphezulu kunye noxinzelelo oluphezulu kuya kukhawulezisa ukuguga kwe-carrier, ngelixa i-reactants ene-sulfure ephezulu okanye i-chlorine ephezulu ingabangela i-carrier carrier. Ke ngoko, iinkampani kufuneka zibeke iliso rhoqo iimeko zokusabela kwaye zandise izicwangciso zolondolozo ngokufanelekileyo. Ngokomzekelo, kwiinkqubo ezinomxholo ophezulu wesulfure, kucetyiswa ukuba unciphise ixesha lokugcinwa ukuze ugweme ukuchithwa kwesulfure kubangela ukuvaleka kwe-pore carrier.
Ukugcinwa kwenzululwazi akunakukwandisa kuphela ubomi bomthwali, kodwa kwakhona kuphucule kakhulu izibonelelo zoqoqosho. Ukucocwa rhoqo kweediphozithi zekhabhoni kunye ne-sediments kunokubuyisela umsebenzi womthwali kunye nokunciphisa ukuphindaphinda kwe-catalyst replacement. Ukongeza, kukwabalulekile ukujonga ubume besakhiwo somthwali ngexesha lolondolozo. Ukuba iintanda ezincinci azifunyanwanga ngexesha, zinokubangela ukuba i-catalyst ziwe kwaye ichaphazele ukhuseleko lwemveliso.
Iingcali zeshishini zincoma ukuba iinkampani ziseke iifayile zokugcinwa kwedijithali ukurekhoda ixesha, iiparameters zenkqubo kunye notshintsho lwelizwe lomthwali wolondolozo ngalunye. Ngohlalutyo lwedatha, intsingiselo yokuthomalalisa ukusebenza komthwali inokuxelwa kwangaphambili ngokuchanekileyo, ukuze kuqulunqwe umjikelo wolondolozo olusengqiqweni ngakumbi. Kwangaxeshanye, ukusetyenziswa kobuchwephesha bokuhlaziya obuphezulu, obufana -nobushushu obuphezulu be-sintering okanye ukucocwa kweekhemikhali, kunokubuyisela ngokufanelekileyo ukusebenza komphathi kunye nokunciphisa iindleko{3}}zexesha elide lokusebenza.
Ngamafutshane, ulawulo lomjikelo wolondolozo lwabathwali be-catalyst likhonkco elibalulekileyo elingenako ukuhoywa kwintsimi yoshishino lweekhemikhali kunye nokukhuselwa kwendalo. Amashishini kufuneka enze izicwangciso zokugcinwa kwenzululwazi ngokusekelwe kwiimpawu zabo zenkqubo, kwaye asebenzise izixhobo zedijithali ukuphumeza ulawulo olusulungekileyo, ukuze kuphunyezwe iinjongo zophuhliso oluzinzileyo ngelixa uqinisekisa ukusebenza kakuhle kwemveliso.
