Parizvino, kushandiswa kukuru kwe pseudo-boehmite ndeyekugadzira alumina uye chinamira che catalyst kana catalyst carrier yakaoma. Alumina inogadzirwa nekugocha pseudo-boehmite ine nzvimbo yakasarudzika uye inoshandiswa zvakanyanya se catalyst uye catalyst carrier muindasitiri ye petrochemical.
1. Inoshandiswa pakugadzira zvinhu zve nanometer alumina
Imwe yeMASHANDISIRO akakosha e pseudo-boehmite imhando yealuminium oxide. Zvichibva pahunhu hwenzvimbo yakakura, kushanda kwakanyanya uye kugona kunyungudutsa zvinhu zvakagadzirwa, yakashandiswa kugadzira ceramics dzinopisa zvakanyanya dzakadai sealuminium nitride ceramics. Pamusoro pezvo, nano-Al2O3 inonyanya kukodzera chemical mechanical polishing (CMP), ne nano-Al2O3 sezvo zvidimbu zvinogadzirwa neCMP slurry zvinogona kushandiswa pakati peIC production process se semiconductor wiring materials uye film materials dzakadai se tungsten, aluminium, copper flattening, uye advanced optical glass, quartz crystal uye akasiyana-siyana gems polishing.
Mufananidzo -Al2O3 inogona kushandiswa pakugadzira makemikari ekupukuta nekugadzira zvinhu zvinokanganisa ganda
2.Kuti hydrogenation iwedzere simba
Kuti zvizadzise zvinodiwa pakushandisa mafuta epetroleum uye mafuta akachena, tekinoroji yehydrogenated yave ichishandiswa zvakanyanya, hydrogenation catalyst ndiyo musimboti wetekinoroji yehydrogenation, inoshandiswa pakugadzira hydrogenation catalyst, gamma alumina catalyst inowanzo kuve ne quasi thin diaspore nekugocha mvura, ine nzvimbo chaiyo yekumusoro, kupinda uye kugoverwa kwemapore anogadziriswa, pamusoro pane nzvimbo dzakasiyana dzeacidic. Simba remuchina riri nani uye kugadzikana kwekupisa, pamwe nehunhu hwakaderera.
Zvishandiso zvemifananidzo zvakakosha pakugadzira zvigadzirwa zvepeturu
Muindasitiri yemazuva ano yekuchenesa mafuta nemakemikari, inopfuura 90% yemaitiro emakemikari ekuita anoitwa nemaitiro ekugadzirisa, saka catalyst yave kiyi yekugadzira maitiro matsva ekuchenesa uye emakemikari, kugadzira zvigadzirwa zvitsva. Muindasitiri yekuchenesa mafuta, ma catalyst akasimba anowanzo shandiswa, ayo anoumbwa ne carrier uye chikamu chinoshanda. Catalyst chikamu chakakosha che catalyst yakasimba, iyo inogona kuwedzera nzvimbo chaiyo, kuvandudza kupisa uye simba remakanika. Catalyst INOSHANDISA mhando dzakawanda dze catalyst, dzakadai se: alumina, molecular sieve, silica gel, silica gel, activated carbon uye diatomaceous earth. Nekudaro, huwandu hwe alumina catalyst hunoita zvinopfuura hafu yehuwandu hwe catalyst catalyst. Catalytic cracking (FCC) catalyst ndiyo musimboti we catalytic cracking process. Sezvo mafuta asina kuchena pasi rose ari mashoma uye asina kunaka, mu catalytic cracking raw material blending heavy oil, residual oil yave nzira inoshandiswa zvakanyanya yekugadzirisa, saka inoda oil catalytic cracking (FCC) catalyst inofanira kunge iri heavy oil molecular diffusion yegomba guru, uye gomba guru riri pakati rinofanira kunge riine acid density yakakodzera, mu kuitira kuvandudza kugona kwekupwanya catalyst yema macromolecular compounds muzvinhu zvakagadziriswa. Active alumina inowanzo shandiswa kuvandudza catalyst matrix. Huwandu hukuru hwemaburi hunobatsira kuti macromolecular compounds afambe mu catalyst particles, nepo nzvimbo yepamusoro chaiyo inobatsira kupararira kwesimbi inoshanda, kuitira kuvandudza mashandiro e catalyst.
3. Inoshandiswa se namira
Chishandiso che diaspore chakatetepa chinoshandiswa sechishandiso chekubatanidza hachingobatsiri pakuumba chete, asi chinokanganisawo mashandiro echishandiso chemagetsi, vaongorori vari muchikamu chekuderedza Ce – Mn/TiO2 chinoshandiswa mukubatanidza chishandiso chemagetsi chemagetsi chakatetepa sechishandiso chekubatanidza, vakaona kuti kwete chete kuti simba remakemikari ema catalysts riwedzere zvakanyanya, asi zvakare chakavandudza chishandiso chemagetsi chemagetsi chemagetsi che denitration surfactant.
4. gadzirisa chifukidziro che -Al2O3
Basa rekuputira jira pamusoro pechinotakura rinowedzera nzvimbo chaiyo yenzira inowanzoshandiswa, gamma alumina ndeimwe yezvinhu zvinonyanya kushandiswa zvekuputira, ine nzvimbo yakakwirira chaiyo, inobatsira chikamu chinoshanda mukupararira kunobudirira mukuita kwekuisa impregnation, kugadzirira gamma alumina coating inowanzoshandiswa yeAlOOH precursor sol, alumina sol kuti ive yakatetepa diaspore sezvinhu zvakabikwa, kugadzirira, nekushandisa nzira ye acid peptization process iri nyore kudzora, inogona kushandiswa mukugadzirwa kwemaindasitiri.
