Njengezinto eziphambili kwimveliso yeekhemikhali, ukusebenza kwe-catalyst carrier ichaphazela ngokuthe ngqo ukusebenza kwe-catalytic, ukuzinza kokuphendula kunye nobomi bezixhobo. Kwiminyaka yakutshanje, kunye nokuqiniswa kwemithetho yokhuseleko lokusingqongileyo kunye nemfuno ekhulayo yokusebenza okuphezulu kunye -nobugcisa obuphantsi bekhabhoni kwishishini lemichiza, inkqubo yokubumba i-catalyst carriers ihamba ngokukhawuleza.
Imigaqo yobugcisa: ubume bumisela ukusebenza
Umsebenzi ophambili wabathwali be-catalyst kukubonelela ngenkxaso esasazekileyo kumacandelo asebenzayo kunye nokwandisa ukuhanjiswa kobuninzi kunye nokusebenza kakuhle kobushushu. Inkqubo yokubumba idinga ukulungelelanisa izibonakaliso ezintathu eziphambili ze-porosity, amandla omatshini kunye nokuzinza kweekhemikhali. Abathwali bemveli ikakhulu basebenzisa izinto ezifana ne-alumina kunye ne-silica, ngelixa abathwali abatsha baphonononga izinto eziphakamileyo kwindawo ethile efana nekhabhoni -i-composites esekwe kunye nesakhelo se-organic organic (MOF) ukuziqhelanisa neemeko zokusebenza ezigqithisileyo ezifana nobushushu obuphezulu kunye nokubola okuqinileyo.
Uhlalutyo lwenkqubo yokubumba eqhelekileyo
Okwangoku, itekhnoloji yokubumba esetyenziswa kakhulu kwishishini ibandakanya ukubumba i-extrusion, ukomisa ukutshiza kunye nokucofa ukubumba. Ukubumba i-Extrusion kucinezela i-slurry ibe kwimilo ethile ngokusebenzisa i-mold, efanelekileyo kwimveliso enkulu ye-honeycomb okanye i-cylindrical carriers kwaye isetyenziswa ngokubanzi kwibala lokucocwa kombhobho wemoto. Indlela yokutshiza yokumisa i-atomizes i-slurry ibe yi-microparticles kwaye ikhawuleze ikhuphe amanzi, enokuthi ilungiselele abathwali be-spherical kunye nobukhulu be-particle size, kwaye isoloko isetyenziswa kwi-petroleum refining catalysts. Ukucofa ukubumba kucinezela umgubo ube ziiflakes okanye iibhloko phantsi koxinzelelo oluphezulu, olulungele imeko-bume yokusabela koxinzelelo oluphezulu, kodwa kufuna ukuchaneka kwezixhobo eziphezulu.
Iindlela zoShishino: Ukwenziwa kohlaza kunye nokwenza ngokwezifiso
Ngokuqhubela phambili kweenjongo "zekhabhoni ezimbini", ukusetyenziswa kwamandla aphantsi-kunye neenkqubo zokubumba eziphantsi{1}}zibe yingqwalasela yophando nophuhliso. Umzekelo, i-microwave{3}}iteknoloji encedisayo yokomisa ingalenza libe lifutshane ixesha lokumisa umoya oshushu kwaye inciphise ukukhutshwa kwekhabhoni; Itekhnoloji yoshicilelo ye-3D inokufezekisa ulwakhiwo oluchanekileyo lwezakhiwo ezintsonkothileyo zepore ukuhlangabezana neemfuno zomntu. Ukongeza, uphuhliso lwezinto {6} ezisekelwe kwi-bio (ezifana ne-lignin derivatives) lukhuthaze ngakumbi uphuhliso oluzinzileyo lweshishini.
Kwixesha elizayo, inkqubo yokubumba i-catalyst carrier iya kuphuhliswa kwicala lobukrelekrele kunye nokusebenza okuninzi. Ngokwandisa ubume bepore ngokwenziwa komfuziselo wedijithali kunye nokudibanisa{1}}kwisitu ubuchwephesha bokulinganisa abalinganiswa ukubeka iliso kwinkqubo yokubumba ngexesha lokwenyani, kulindeleke ukuba iphucule ngakumbi ukusebenza kakuhle kunye nokunciphisa iindleko zemveliso. Ukuphumelela kule ntsimi kuya kunika inkxaso ebalulekileyo yokuguqulwa kohlaza kwishishini lemichiza.
