Vim li cas tswj cov impurities hauv V₂O₅ yog qhov tseem ceeb
Cov impurities hauv vanadium pentoxide cuam tshuam ncaj qhametallurgical thiab catalytic txheej txheem, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov ferrovanadium thiab sulfuric acid catalysts.
Hlau (Fe) yog qhov tseem ceeb tshaj plaws vim nws tuaj yeem:
hloov qhov sib npaug ntawm vanadium txo thaum lub sij hawm FeV ntau lawm
txo qhov purity ntawm qhov kawg alloy
cuam tshuam rau stability ntawm yaj
Silicon (Si) thiab aluminium (Al) tuaj yeem:
txo cov txiaj ntsig ntawm vanadium hauv kev txo qis
nce tus nqi ntawm slag
impair reactivity efficiency nyob rau hauv metallurgy
Sulfur (S) thiab phosphorus (P) yog qhov tseem ceeb tshwj xeeb raukev siv catalyticTxawm li cas los xij, txawm tias cov lej tuaj yeem:
tshuaj lom cov catalyst
txo cov kev ua ntawm SO₂ → SO₃ cov tshuaj tiv thaiv
shorten lub neej catalyst
Yog li ntawd, high-purity V₂O₅ qib (99.5% thiab 99.7%) xav taunruj tswj ntawm raw cov ntaub ntawv, melting thiab crystallizationkom txo qis impurities.
Qhov zoo sib txawv li cas ntawm qib purity?
Thaum hloov los ntawm 98.5% mus rau 99.7%:
Fe cov ntsiab lus txo los ntawm kwv yees li 2-3 zaug
Si thiab Al raug txo vim yog cov khoom siv huv huv thiab kev ua kom huv huv
S thiab P yog tswj ntawm qib ppm, tseem ceeb rau catalysts
Qhov no txhais tau hais tias ntau dua purity ncaj qha muab:
ruaj khov tshuaj tiv thaiv
ntau cov txiaj ntsig ntawm vanadium hauv FeV
ncua kev pabcuam catalyst lub neej
Kev sib piv ntawm V₂O₅ hom los ntawm impurities
V₂O₅ 98.5% vs V₂O₅ 99.5%
Qib 98.5% tso cai rau qib siab dua ntawm Fe, Si thiab Al, ua rau nws tsim nyog rau kev tsim khoom loj ntawm ferrovanadium qhov twg qhov sib txawv me me hauv kev sib xyaw tsis tseem ceeb. Txawm li cas los xij, hauv catalysts xws li impurities tuaj yeem txo qhov kev ua haujlwm thiab kev ruaj ntseg ntawm kev ua haujlwm.
Qib 99.5% muaj kev tswj hwm nruj dua ntawm impurities, tshwj xeeb tshaj yog S thiab P, ua rau nws tsim nyog rau kev lag luam tshuaj. Nws muab cov tshuaj ntxuav kom huv thiab ua kom zoo dua qub hauv sulfuric acid ntau lawm thiab cov txheej txheem oxidation.
V₂O₅ 99.5% vs V₂O₅ 99.7%
99.5%. Nws yog siv nyob rau hauv feem ntau catalyst thiab tshuaj txheej txheem.
99.7%. Qhov no yog qhov tseem ceeb tshwj xeeb rau:
high-precision catalysts
Kev siv electrochemical
ntev industrial txheej txheem nrog siab rhiab heev
Qhov txawv yog manifested nyob rau hauv tus txheej txheem stability thiab khoom siv lub neej.
