Yini i-vanadium pentoxide catalyst?

UVanadium Pentoxide (V2O5) ungenye yezindlela eziguquguqukayo nezingahambi kahle ze-oxidation catalysts ezisetshenziswa embonini yanamuhla. Ukusuka ekukhiqizweni okukhulu kwe-sulfuric acid ukukhiphela i-oxidation kumakhemikhali amahle, ukwakheka okusekwe ku-v2o5 ukuletha ukusebenza okufakazelwe, ukuqina, kanye nokusebenza kwezindleko. Njengoba ukuguqulwa kwamandla kuyashesha futhi izinqubo zokuhlanza ziba zibalulekile, ama-v2o5 ama-catalysts athola ukunwebeka izindima kuma-emussions control, amabhethri e-sodium-ion, kanye nemigwaqo yamakhemikhali enoveli anciphisa imfucuza futhi andise ukukhetha.

Yini i-pentoxide ye-vanadium?

UVanadium Pentoxide CatalystV2o5Ingabe i-oxidation eqinile, enamandla aphezulu ngokusetshenziswa okubanzi e-sulfuric acid, i-anhydride ye-anhydride, i-anhydride ye-phthalic, kanye nokukhetha i-oxidation of light hydrocarbons nama-aromatics.
Ukusebenza kwe-catalytic kuncike esigabeni se-crystal, indawo engaphezulu, i-oxidation State Dynamics (V5 + v4 + redox)
I-Supply Chain ingumhlaba wonke, i-aresning ye-vanadium-ethwele ama-ores, ama-slags ensimbi, nezinsalela zikaphethiloli. Ukuqinisekiswa kwekhwalithi, ukulawulwa kokungapheli, kanye nokwakheka kwesigaba okungaguquki kubalulekile ukuthola imiphumela evuselelayo.
Ukuphepha kanye nezenzo zezemvelo zibalulekile ngenxa yemvelo ewonakalisayo nenobuthi yamakhompiyutha we-vanadium; Ukuphatha amandla, ukupakisha, kanye nohlaka lokuhambisana nakho kuyimpoqo.
Amathuba asafufusa afaka ama-carlysts we-ammonia-to-Power Power, i-VOC ukutakula, ama-SPRIT Khreditani Cathodes, kanye ne-Sodium-Ion Cathodes usebenzisa i-V2O5 Derivatives.

Izakhiwo eziyisisekelo:

Isisindo Molecular: 181.88 g mol
Iphoyinti Lokuncibilika: ~ 690 ° C (ukubola)
Ubuningi: ~ 3.36 g cm³
I-Solubity: incibilika kancane emanzini; incibilike kuzixazululo ezinamandla ze-alkali ezakha amabanga
Isakhiwo se-Crystal: Orthorhombic esigabeni esivame kakhulu; Isakhiwo esibunjiwe silungele ukuhlukaniswa kwezinqubo ze-redox

Ama-catalysts wezentengiso ahlinzekwa ngezindlela eziningana:

• I-Bulk v2o5 (i-powder noma i-flake): I-pentoxiium ebumsulwa ephezulu esetshenziswa njengengqayizivele ye-catalyst yenziwa noma ngokuqondile njengesengezo.
• Ama-Catalysts asekelwa:UVanadium Pentoxide Catalyst I-V2O5 ehlakazeke kubathwali be-porous, babunjwe ngama-pellets, izindandatho, izihlalo ezidabukisayo, noma izinyosi. Ukulayisha okujwayelekile kusuka kusuka ku-1-10 wt% v2o5, kepha kungahluka kakhulu.
• Ama-Catalysts ahlelekile kanye nama-monoliths: Okwenziwa kwe-SCR ne-VOC, i-V2O5 ifakwa ku-HoneyComb Monoliths, amapuleti, noma izinhlaka ezihlanganisiwe zisebenzisa ama-Inorganic Binders Nabaphromoshi.
• Izakhi ezikhethekile: I-V2O5 ehlanganiswe ne-phosphorus (VPO System), Molybdenum, Tungsten, Titanium, NIOBIM, kanye ne-Alkaline Metals enzelwe ukusabela.

Amabanga amsulwa:

Ibanga lobuchwepheshe:Ilungele i-Oxidation eningi lapho ukungcola kokungcola kubekezelelwa ngaphakathi kwe-spec. Ukungcola okujwayelekile: FE, NI, NA, K, P, P, S, CL.
Ibanga eliphakeme lokuhlanzeka:Amazinga wokungcola aphansi wezinqubo ezibucayi ze-catalytic noma ukusetshenziswa kwe-electrochemical.
Ibanga lebhethri nebanga lokucwaninga:Imikhawulo eqinile kuma-alkali, chloride, kanye nomswakama okuqukethwe; Ukusatshalaliswa kosayizi abalawulwa yizinhlayiyana kanye nendawo ethize engaphezulu.
