Icatalyst carrier ni igice cyihariye cya catalyst ikomeye, dispersant, binder, negative carrier y'igice gikora cya catalyst, rimwe na rimwe ACTS nka co-catalyst cyangwa co-catalyst. Icatalyst carrier, izwi kandi nk'inkunga, ni kimwe mu bigize catalyst ishyigikiwe. Muri rusange, ni ibikoresho bifite utwenge dufite ubuso runaka, kandi igice gikora cya catalyst gikunze gushyirwaho. Icatalyst ikoreshwa cyane cyane mu gushyigikira igice gikora, ku buryo catalyst igira imiterere yihariye, mu gihe icatalyst ubwayo muri rusange idafite imikorere ya catalyst.
Ibisabwa ku nkunga ya Catalyst
1, ishobora kugabanya ubucucike bw'ibice bikora, cyane cyane ibyuma by'agaciro
2, ishobora gutegurwa mu buryo runaka
3. Gucikamo ibice hagati y'ibice bikora bishobora kwirindwa ku rugero runaka
4, ishobora kurwanya uburozi
5. Bishobora kugira ingaruka ku gice gikora n'igikangurambaga cy'ingenzi.
Ingaruka z'umuyoboro w'ibikoresho bya katalisiti
1, kugabanya ikiguzi cya catalyst
2, kunoza imbaraga za mekanike za katalyst
3. Kunoza ubushyuhe buhamye bwa catalyst
4, ongeramo ibikorwa bya catalyst n'uburyo bwo guhitamo
5. Kongera igihe cy'ubuzima bwa catalyst
Hashyizweho uburyo butandukanye bwo gutwara ibintu by'ibanze
1. Alumina ikora: ikoreshwa cyane mu gutwara ibintu bikoreshwa mu nganda. Igiciro gito, irwanya ubushyuhe bwinshi, ihura neza n'ibice bikora.
2. Jeli ya silica: imiterere y'imiti ni SiO2. Muri rusange ikorwa muri aside ya sodium silicate (na 2 si 3). Aside silicate yaremwe nyuma y'ingaruka za sodium silicate na aside. Polimasiyo ya aside silicate, guhumeka, imiterere ya polymer ntabwo isobanutse neza.
SiO2 ni igikoresho gikoreshwa cyane, ariko ikoreshwa mu nganda ni nkeya ugereranyije na Al2O3, ibi biterwa n'ingorane mu gutegura, isano idakomeye n'ibice bikora, gushonga byoroshye n'umwuka w'amazi n'ibindi bidafite ubuziranenge.
3. Diatomite: SiO2 karemano. Irimo okiside nke z'icyuma n'ibintu bikomoka ku bimera, hamwe n'imiterere y'imyobo yayo n'impinduka zihariye z'ubuso bitewe n'aho ikomoka. Gutunganya aside bigomba gukoreshwa mbere yo kuyikoresha. Kimwe ni ukunoza ingano ya SiO2 no kongera ubuso bwihariye, ingano y'imyobo yihariye n'umurambararo w'imyobo y'ibanze. Icya kabiri ni ukunoza ubushyuhe, nyuma yo gutunganya aside, bishobora kongera ubuso bwihariye. Diatomite ikoreshwa cyane cyane mu gutegura catalysts zihamye.
4, karuboni ikora: ikintu cy'ingenzi ni C, irimo H, O, N, S n'ivu bike, nibindi. Karuboni ikora ifite imiterere idahwitse y'urusyo rw'amabuye, hari itsinda rya karuboni, itsinda rya quinone, itsinda rya hydroxyl n'itsinda rya karuboni ku buso. Karuboni ikora irangwa n'imyenge ikomeye n'ubuso bunini, ubushyuhe buhamye n'ubushyuhe bwinshi.
5. TiO2: ifite imiterere itatu ya kristu: anatase, titaniyumu ya plate na rutile. Ubutare bwa titaniyumu bugoye kubuvanga bitewe no kudahindagurika; Anatase ikorwa ku bushyuhe buri hasi ifite ubucucike bwa 3.84 n'ubuso bunini bwihariye. Iyo ishyushye kuri 600 ~ 1000°C, anatase iba rutile, ifite ubucucike bwa 4.22 n'ubuso buto bwihariye.
6. Karubide ya silikoni: aho karubide ishongesha ni hejuru ya 2000°C, ifite ubushyuhe bwinshi, ubukana bwinshi, ubushyuhe bukomeye kandi irwanya ingaruka, ariko irasubikwa gusa mu kirere cya ogisijeni. Rero SiC ikunze gukoreshwa nk'umuyoboro w'ingufu mu bidukikije birimo ubushyuhe bwinshi.
7. Urusenda rwa molekile: ni kristu silicate cyangwa silicoaluminate, umwobo n'ubuso bigizwe na tetrahedron ya silico-okisijene cyangwa tetrahedron ya aluminiyumu ihujwe n'imigozi ya ogisijeni. Ifite ubushyuhe bwinshi, ubushyuhe bw'amazi buhamye kandi irwanya aside na alkali.
