MaCatalyst Anotsigirwa neAlumina: Mutambi Akakosha muIndasitiri yeMakemikari

Macatalyst anotsigirwa neAlumina anoita basa rakakosha mumabasa akasiyana-siyana emakemikari, zvichiita kuti ave chinhu chakakosha muindasitiri yemakemikari. Macatalyst aya anoshandiswa zvakanyanya mukushandiswa kwemafuta, mishonga, uye nharaunda, nekuda kwehunhu hwavo hwakanaka uye kushanduka-shanduka. Muchinyorwa chino, tichaongorora kukosha kwemacatalyst anotsigirwa nealumina, mashandisirwo awo, uye zvinhu zvinopesvedzera mitengo yawo, kunyanya kutarisa pamutengo wegamma alumina, aluminium oxide ball, uye activated alumina catalyst.

Macatalyst anotsigirwa neAlumina macatalyst umo chikamu chinoshanda checatalytic chinoparadzirwa panzvimbo yakakwirira yealumina inotsigira. Kushandiswa kwealumina sechinhu chinotsigira kune zvakanakira zvakawanda, zvinosanganisira nzvimbo yakakwirira, kugadzikana kwekupisa, uye kuramba makemikari akaomarara. Macatalyst aya anoshandiswa zvakanyanya mumabasa akadai se hydrocracking, hydrotreating, uye catalytic reforming muindasitiri yekuchenesa peturu. Pamusoro pezvo, anoshandiswa mukugadzira makemikari akasiyana-siyana, anosanganisira mapolymers, mapurasitiki, uye mishonga yemishonga.

Chimwe chezvinhu zvakakosha zvema catalysts anotsigirwa nealumina i gamma alumina, inova rudzi rwe alumina ine crystalline inozivikanwa nenzvimbo yayo yepamusoro uye porosity. Mutengo we gamma alumina chinhu chakakosha pamutengo we catalysts anotsigirwa nealumina. Mitengo ye gamma alumina inokanganiswa nezvinhu zvakati wandei, kusanganisira mutengo wezvinhu zvakagadzirwa, mitengo yesimba, uye kudiwa kwemusika. Pamusoro pezvo, mhando nekuchena kwe gamma alumina kunokanganisawo mutengo wayo, sezvo magiredhi epamusoro ekuchena achitungamira pamutengo wepamusoro mumusika.

Chimwe chinhu chakakosha chine chekuita nema catalysts anotsigirwa nealumina ibhora realuminium oxide. Mabhora aya anoshandiswa sechishandiso che catalysts, zvichipa nzvimbo yakagadzikana uye isina simba yezvikamu zvinoshanda zve catalytic. Mitengo yemabhora ealuminium oxide inokonzerwa nezvinhu zvakaita semitengo yekugadzira, kudiwa kwemusika, uye kuwanikwa kwezvinhu zvakagadzirwa. Saizi uye chimiro chemabhora zvinoitawo basa mukusarudza mutengo wawo, sezvo mabhora madiki uye akafanana anowanzo kudhura zvakanyanya nekuda kwekuita kwakakodzera mukugadzirwa kwawo.

Alumina catalyst inoshanda chimwe chinhu chakakosha mukugadzira macatalyst anotsigirwa nealumina. Alumina inoshanda ine maburi akawanda anozivikanwa nekupinza kwayo uye kugona kwayo kupinza. Inoshandiswa zvakanyanya se catalyst uye kutakura makemikari akasiyana-siyana, kusanganisira kucheneswa kwemagasi nemvura. Mitengo ye activated alumina catalyst inokonzerwa nezvinhu zvakaita sehuwandu hwe activation, nzvimbo yepamusoro, uye huwandu hwe pore. Mazinga e activation akakwira uye nzvimbo dzakakura dzepamusoro dzinoda mitengo yakakwira nekuda kwekuwedzera kwe catalytic activity uye adsorption capacity.

Kushandiswa kwakasiyana-siyana kwema catalysts anotsigirwa nealumina kunosvika pakushandiswa kwawo se catalysts mumakemikari akasiyana-siyana. Kusarudzwa kwe catalysts kunokosha pakuona mashandiro uye kushanda zvakanaka kwe catalyst system. Catalysts dzinotsigirwa nealumina dzinopa simba rakanaka remuchina, kugadzikana kwekupisa, uye kuramba chepfu, zvichiita kuti dzive sarudzo yakakodzera kune akasiyana-siyana mashandisirwo e catalytic. Mutengo wema catalysts anotsigirwa nealumina se catalysts unokonzerwa nezvinhu zvakaita senzvimbo chaiyo, kupararira kwe pore size, uye nzira yekugadzirira.

Mukupedzisa, macatalysts anotsigirwa nealumina akakosha muindasitiri yemakemikari, achiita basa rakakosha mumabasa akawanda emakemikari. Mitengo yemacatalysts aya inokonzerwa nezvinhu zvakasiyana-siyana, kusanganisira mutengo wezvinhu zvakagadzirwa, mitengo yesimba, kudiwa kwemusika, uye hunhu hwezvinhu zvecatalyst zvakaita segamma alumina, aluminium oxide balls, uye activated alumina. Sezvo kudiwa kwemacatalysts anoshanda uye anogara kwenguva refu kuri kuramba kuchikura, macatalysts anotsigirwa nealumina akagadzirira kuramba ari mutambi mukuru mukusimudzira hunyanzvi nekufambira mberi muindasitiri yemakemikari.
