Sechinhu chakakosha mukugadzirwa kwemakemikari, kuita kwecatalyst carrier kunobata zvakanangana necatalytic performance, kugadzikana kwekuita uye hupenyu hwemidziyo. Mumakore achangopfuura, nekuomeswa kwemitemo yekuchengetedzwa kwezvakatipoteredza uye kudiwa kuri kuramba kuchikwira kwe-kunyatsoshanda uye kushomeka{2}}kabhoni tekinoroji muindasitiri yemakemikari, kuumbwa kwezvinotakura zvinotakura zvinhu kuri kuitika nekukurumidza. Chinyorwa ichi chichaongorora mafambiro ekupedzisira mundima iyi kubva pazvinhu zvitatu: misimboti yehunyanzvi, maitiro akajairika uye maitiro emaindasitiri.
Technical misimboti: chimiro chinotemesa kuita
Basa repakati revatakuri vecatalyst kupa rutsigiro rwakapararira rwezvinhu zvinoshanda uye kukwidziridza kutamisa hukuru uye kugona kutamisa kupisa. Kuumbwa kwayo kunoda kuenzanisa zviratidzo zvitatu zvikuru zveporosity, simba remagetsi uye kugadzikana kwemakemikari. Vatakuri vechinyakare vanonyanya kushandisa zvinhu zvakaita sealuminium nesilika, nepo vatakuri vatsva vachiongorora zvinhu zvepamusoro-soro senge kabhoni-based composites uye metal organic frameworks (MOF) kuti zvienderane nemamiriro ekushanda zvakanyanya senge tembiricha yakanyanya uye ngura yakasimba.
Kuongororwa kweiyo mainstream molding process
Parizvino, iyo inonyanya kushandiswa tekinoroji yekuumba muindasitiri inosanganisira extrusion kuumba, kupfapfaidza kuomesa uye kudzvanya kuumba. Extrusion molding inodzvanya slurry kuita chimwe chimiro kuburikidza ne mold, iyo inokodzera kugadzirwa kukuru-kwemwero wemizinga yehuchi kana cylindrical carriers uye inoshandiswa zvakanyanya mundima yekunatsa exhaust yemotokari. Iyo yekupfapfaidza yekuomesa nzira inoisa slurry kuita microparticles uye yobva yakurumidza kuibvisa, iyo inogona kugadzirira spherical carriers neuniform particle size, uye inowanzoshandiswa mu petroleum refining catalysts. Kudzvanya molding kunodzvanya poda kuita maflakes kana mabhuroko pasi pekumanikidza kwakanyanya, izvo zvinoenderana nepamusoro-nzvimbo dzinoita kudzvanywa, asi zvinoda kunyatsojeka kwemidziyo.
Industry Trends: Greening uye Customization
Nekufambira mberi kwezvinangwa zve "dual carbon", kushomeka-simba rekushandisa uye kushomeka-magadzirirwo ekuumba emission zvave chinangwa chetsvakiridzo nebudiriro. Semuyenzaniso, microwave-yakayamurwa yekuomesa tekinoroji inogona kupfupisa nguva yechinyakare yekuomesa mhepo inopisa uye kuderedza kuburitsa kabhoni; 3D yekudhinda tekinoroji inogona kuwana chaiyo kuvakwa kweakaomesesa pore zvimiro kuti asangane nemunhu anokonzeresa zvinodiwa. Pamusoro pezvo, kugadzirwa kwezvinhu zvebio{{6}based carrier materials (sezvinobva ku lignin) zvakasimudzira budiriro yeindasitiri.
Mune ramangwana, iyo catalyst carrier molding process ichakura munzira yehungwaru uye multifunctionality. Nekukwenenzvera chimiro chepore kuburikidza nedhijitari modhi uye kubatanidza mu-situ characterization tekinoroji kuona mafambisirwo ezvipo munguva chaiyo, zvinotarisirwa kuenderera mberi nekunatsurudza kushanda zvakanaka uye kuderedza mitengo yekugadzira. Kubudirira mundima iyi kuchapa rubatsiro rwakakosha kune shanduko yakasvibira yeindasitiri yemakemikari.
