Nchịkọta nke alumina arụ ọrụ
Alumina arụ ọrụ, nke a makwaara dị ka activated bauxite, ka a na-akpọ alumina activated na bekee. Alumina eji eme ihe na-eme ka a na-akpọkarị “alumina arụ ọrụ”. Ọ bụ ihe siri ike gbasasịa nke ukwuu nke nwere nnukwu akụkụ elu. N'elu microporous ya nwere njirimara achọrọ maka catalysis, dị ka arụmọrụ adsorption, ọrụ elu, nkwụsi ike dị mma nke okpomọkụ, wdg, n'ihi ya, a na-ejikarị ya eme ihe dị ka ihe na-eme ka ọkpụkpụ na-ebu maka mmeghachi omume kemịkalụ.
The Spherical activated alumina mgbali swing mmanụ adsorbent bụ ọcha sppherical porous ahụ. The arụ ọrụ alumina nwere edo urughuru size, ezigbo elu, elu n'ibu ike, ike hygroscopicity, adịghị aza na mgbawa mgbe mmiri absorption, na-anọgide na-agbanweghi agbanwe. Ọ bụ ihe na-adịghị egbu egbu, enweghị isi, na-adịghị edozi ya na mmiri na ethanol.

Ọ naghị agbaze n'ime mmiri ma nwee ike jiri nwayọọ nwayọọ gbazee na sulfuric acid gbasiri ike. Enwere ike iji ya mee ka aluminom ọla dị mma ma bụrụkwa ihe eji eme ihe eji eme crucibles, poselin, ihe mgbagha na nkume dị egwu.
Alumina eji eme ihe dị ka adsorbent, catalyst na catalyst carrier ka a na-akpọ “alumina arụ ọrụ”. Ọ nwere njirimara nke porosity, mgbasa ozi dị elu na nnukwu ebe elu kpọmkwem. A na-eji ya n'ọtụtụ ebe na ọgwụgwọ mmiri, petrochemical, ezigbo kemịkalụ, ndu na ọgwụ ubi.
Njirimara nke alumina
1. Nnukwu ebe dị elu: alumina na-arụ ọrụ nwere ebe dị elu dị elu. Site n'ụzọ ziri ezi ịchịkwa sintering usoro nke alumina, arụ ọrụ alumina na a kpọmkwem elu ebe dị elu dị ka 360m2 / G nwere ike kwadebere. Alumina a na-arụ ọrụ nke a kwadebere site na iji colloidal aluminum hydroxide decomrated site NaAlO2 dị ka akụrụngwa nwere obere pore nha na mpaghara elu dị elu dị ka 600m2 / g.
2. Nhazi nha nha nke na-agbanwe agbanwe: N'ikwu okwu n'ozuzu, ngwaahịa nwere oke nha nha nwere ike ịkwadebe site na mmiri na aluminom hydroxide dị ọcha. Obere pore size ngwaahịa nwere ike kwadebere site na-akwadebe activated alumina na aluminum gluu, wdg mgbe nnukwu pore size na-arụ ọrụ alumina nwere ike kwadebere site na-agbakwunye ụfọdụ organic bekee, dị ka ethylene glycol na eriri, mgbe combustion.
3. N'elu bụ acidic ma nwee ezigbo nkwụsi ike okpomọkụ.
Ọrụ nke alumina na-arụ ọrụ
Alumina na-arụ ọrụ bụ nke ụdị alumina kemịkalụ, nke a na-ejikarị dị ka adsorbent, purifier water, catalyst and catalyst carrier. Alumina na-arụ ọrụ nwere ike ịhọpụta mmiri na gas, uzuoku mmiri na ụfọdụ mmiri mmiri. Mgbe adsorption na-ejupụta, ọ nwere ike ikpo ọkụ na ihe dịka 175-315. D egere. Enwere ike ịmegharị adsorption na reactivation ọtụtụ oge.
Na mgbakwunye na-eji dị ka a desiccant, ọ nwekwara ike banye lubricating mmanụ vepo si mmeru oxygen, hydrogen, carbon dioxide, eke gas, wdg Na ike ji mee ihe dị ka ihe na-akpali akpali na nkwado nkwado na dị ka nkwado maka chromatographic analysis.
Enwere ike iji ya dị ka onye na-emepụta ihe na-eme ka mmiri dị elu nke fluorine dị elu (nke nwere ikike dị ukwuu), onye na-emepụta ihe na-emepụta ihe na-eme ka alkanes na-ekesa na mmepụta nke alkylbenzene, onye na-emepụta ihe na-emepụta ihe na-eme ka mmanụ na-agbanwe agbanwe, onye na-ehichapụ gas na ikuku oxygen na-emepụta ụlọ ọrụ. , ụlọ ọrụ textile na ụlọ ọrụ eletrọnịkị, onye na-ehicha ihe maka ikuku ngwa ngwa, na onye na-ehicha ihe na ihe na-eme ka ọ dị ọcha na fatịlaịza kemịkalụ, ihicha petrochemical na ụlọ ọrụ ndị ọzọ.
