Njengezinto eziphambili kwimveliso yeekhemikhali, indlela yokubunjwa kwe-catalyst carrier ichaphazela ngokuthe ngqo ukusebenza kunye nobomi benkonzo ye-catalyst. Ngophuhliso olukhawulezayo lweshishini lemichiza yehlabathi, imfuno yabathwali be-catalyst iyaqhubeka nokukhula, ngakumbi kwimimandla yokhuseleko lokusingqongileyo, amandla kunye neekhemikhali ezilungileyo. Ukuqonda indlela yokwakhiwa kwabathwali be-catalyst akuyi kunceda nje ukuphucula umgangatho wemveliso, kodwa kuya kuphucula ukukhuphisana kwamashishini kwimarike yamazwe ngamazwe.
Umsebenzi oyintloko wabathwali be-catalyst kukubonelela ngenkxaso kumacandelo asebenzayo, ukuphucula i-dispersibility, kunye nokuphucula ukuzinza kwe-thermal kunye namandla omatshini. Izinto eziqhelekileyo zokuthwala ziquka i-alumina, i-silica, i-carbon activated, i-molecular sieves, njl. Ezi zixhobo zisetyenziswa ngokubanzi kwiindidi ezahlukeneyo ze-catalysts ngenxa yeempawu zabo ezizodwa kunye neekhemikhali. Ngokomzekelo, i-alumina isoloko isetyenziselwa ukucocwa kwepetroleum kunye ne-automobile exhaust purification catalysts ngenxa yendawo yayo ephezulu kunye nokuzinza kwe-thermal; ngelixa iisefu zemolekyuli ziqhuba kakuhle ngokwemilo{3}}i-catalysis ekhethiweyo ngenxa yokwakheka kwe pore rhoqo.
Indlela yokuqulunqa i-catalyst carriers idla ngokubandakanya amanyathelo amathathu abalulekileyo: ukukhethwa kwezinto eziluhlaza, inkqubo yokubumba kunye nokuguqulwa kwendawo. Ukukhethwa kwezinto eziluhlaza kugqiba iimpawu ezisisiseko zomthwali, njenge-porosity, indawo ethile yendawo kunye nokuzinza kweekhemikhali. Inkqubo yokubumba iqhuba izinto eziluhlaza zibe yimilo efanelekileyo kwizicelo zamashishini ngokukhupha, ukutshiza ukutshiza okanye ithebhulethi. Ukuguqulwa komphezulu yinxalenye ebalulekileyo yokuphucula ukusebenza komthwali. Ngonyango lwe-asidi, unyango lwe-alkali okanye ukulayishwa kwezinyithi ezisebenzayo, iimpawu zomphezulu womthwali zinokuphuculwa kwaye ukusebenzisana kwayo kunye namacandelo asebenzayo kunokwandiswa.
Kwintsimi yorhwebo lwangaphandle, umgangatho wobugcisa kunye nomgangatho wemveliso wabathwali be-catalyst uchaphazela ngqo ukukhuphisana kwamanye amazwe. Ngemigaqo yokusingqongileyo eya ingqongqo kwihlabathi jikelele, kukho imfuno emandla yabathwali bezinto ezixhobisayo abasebenzayo nabanobuhlobo nokusingqongileyo. Amashishini kufuneka aqhubeke ekhulisa indlela yokwakheka kunye nokuphucula ukusebenza kwemveliso ukuhlangabezana neemfuno ezahlukeneyo zemarike yamazwe ngamazwe. Kwangaxeshanye, ukomeleza intsebenziswano namaziko ophando lwenzululwazi ngamazwe kunye nokwazisa ubugcisa obuphambili kukwayindlela ebalulekileyo yokwandisa ukhuphiswano.
Ngamafutshane, indlela yokuqulunqa i-catalyst carriers yinkalo ye-multidisciplinary, kwaye inkqubela yayo yezobuchwepheshe ibaluleke kakhulu ekuphuhliseni ishishini lemichiza kunye norhwebo lwangaphandle. Amashishini kufuneka aqhubeke nokunikela ingqalelo kwiintsingiselo zeshishini kwaye avelise iinkqubo zemveliso ukuze athathe indawo enenzuzo ngakumbi kwimarike yehlabathi.
