Catalysts zvinhu zvakakosha mumaindasitiri akasiyana siyana, zvichiita kuti kukurumidza kwemakemikari kuita uye kugadzirwa kwezvinhu zvakakosha. Nekudaro, kushanda kweiyo catalyst kunowanzo kutsamira pane yayo inotakura zvinhu, iyo inopa yakagadzikana uye inoshanda chikuva cheiyo catalytic chiitiko. Muchinyorwa chino, tichaongorora kukosha kwevatakuri vanotakura, mhando dzavo, uye basa ravo mukusimudzira mashandiro anoita catalyst.
Kunzwisisa Catalyst Vatakuri
A catalyst carrier, inozivikanwawo secatalyst tsigiro, chinhu chakasimba chinoshanda sepuratifomu yeanoshanda catalytic zvikamu. Inopa nzvimbo yakakwirira yepamusoro yekupararira kwemhando ye catalytically active uye inopa rubatsiro rwemagetsi kuti ive nechokwadi chekugadzikana uye hupenyu hurefu hwechinokonzera. Vatakuri veCatalyst vanoita basa rakakosha mukuona kuita kwese uye kugona kweiyo catalyst system.
Mhando dzeCatalyst Carriers
Zvinhu zvakasiyana-siyana zvinogona kushandiswa se catalyst vatakuri, imwe neimwe iine yakasarudzika zvimiro uye zvakanakira. Zvimwe zvezvinonyanya kushandiswa catalyst carriers zvinosanganisira:
1. Porous Ceramics: Zvishandiso zvakadai sealuminium, silica, uye zeolites zvinoshandiswa zvakanyanya se catalyst carriers nekuda kwepamusoro penzvimbo yavo, kugadzikana kwekupisa, uye kusagadzikana kwemakemikari. Iyi porous ceramics inopa yakanakisa puratifomu yekuisa emhando dzecatalytic uye inopa kuramba kwakanaka kune yakaoma kushanda mamiriro.
