Chii chinonzi Vanadium Pontoxide Catalyst?

Vanadium Pentoxide (V2O5) ndeimwe yeanonyanya kuita uye kukosha oxidation catalysts inoshandiswa kune indasitiri yazvino. Kubva pane yakakura-chiyero kugadzirwa kweSulfutic acid kusarudza oxidation mumakemikari akanaka, V2O5-yakavakirwa mafomu anonunura kuita kwakaratidza, kusimba, uye kubhadhara-kwakanyanya. Sezvo kushanduka kwesimba kuchinyudza uye kuchenesa maitiro

Chii chinonzi Vanadium Pentoxide?

Vanadium Pentoxide CatalystV2o5Kubira, kwakakwirira-chiitiko oxidation catalyst nekupararira kwekushandiswa muSarufacsic acid, maleic Anhydride, phthalic Andhiydride, uye inosarudza oxidation yechiedza hydrocarbons uye anomatics.
Catalytic performance zvinoenderana nekristaro chikamu, nzvimbo yemusoro, oxidation state dynamics (v5 + / / / / / / / / / / (mo,
Iyo yekupa ketani iri pasi rose, spanning unadium-inobereka Ores, yakarova mashizha, uye peturu inosimbisa. Kuvhevedza Kwemhando, Kusachena Kwekuzvisachena, uye kujairika chikamu chekuumbwa kwakakosha kwemhedzisiro yemubereki.
Kuchengetedzwa uye maitiro ezvakatipoteredza kwakakosha nekuda kwehunhu hunokoshesesa uye hwehupfu hweVanadium Compounds; Sunga kubata, kurongedza, uye kutevedzera mitambo yemitambo inosungirwa.
Mikana yekubuda inosanganisira inochengetera AMMONIA SIMBONA

Zvivakwa zvekutanga:

Solley Huremu: 181.88 G / Mol
Melting Point: ~ 690 ° C (DeComses)
Density: ~ 3.36 g / cm³
Solubility: zvishoma zvishoma mumvura; nyura mumhinduro dzakasimba dzeAlkali dzinoumba vasingatendeke
Crystal chimiro: Orthorhombic yeiyo yakajairika chikamu; yakarongedzwa chimiro chakanakira kuwirirana uye redox maitiro

Commerce V2O5 CATALYSTS inopihwa mumhando dzinoverengeka:

• Bulk v2o5 (poda kana kuputika): yakakwirira-yakanyanya nyadium pentoxide inoshandiswa sepamberi pechidimbu chekugadzira gadzira kana zvakananga seyakawedzera.
• Yakatsigirwa CATALYSTS:Vanadium Pentoxide Catalyst V2O5 akapararira pane zvekutakura zvinhu zvekupenya, akaumbwa kuita mapeya, mhete, zvisungo, kana huchi. Chaizvoizvo kutakura huwandu kubva ku1-10 wt% v2o5, asi inogona kusiyana zvakanyanya.
• Yakarongedzwa CATALYSTS uye monoliths: Zvekuita Scr uye V8C Abatement, V2O5 inobatanidzwa mune huchi monoliths, mahwendefa, kana zvimiro zvakashata zvichishandisa malorganic binders uye vanokurudzira.
• Nhau dzehunyanzvi: V2O5 Yakasanganiswa nePhosphorus (VPO System), Molybdenum, Tungsten, Titanium, Niobium, uye Alkaline Simbi Yakagadzirirwa Kuisa Pfungwa.

Kuchiva Kwemakirimo:

Technical Giredhi:Yakakodzera kune yakawanda oxidation iyo inoteedzera kusvibiswa kunobvumidzwa mukati mechokwadi. Kwayedza kusachena: fe, ni, na, k, si, p, s, c.
Yakakwirira-Pollity Giredhi:Desirange yakachena masekiseni emhando dzinotyisa dzinotyisa maitiro kana electrochemical shandisa.
Battery giredhi uye yekutsvaga giredhi:Miganhu yakasimba paAlkali simbi, chloride, uye unyoro hwemukati; inodzorwa chidimbu chikamu kugovera uye nzvimbo yakatarwa pamusoro.
