Ua tiav Technology thiab Catalyst rau M / P-Xylene Ammoxidation Txheej Txheem / P-Xylonitrile

M / p-xylene ammoxidation rau p / p-xylene nitrile thev naus laus zis yog ua raws li M / p-xylene, helium, thiab huab cua ua cov khoom siv raw, los ntawm cov roj theem nitrogen oxidation cov tshuaj tiv thaiv los tsim M / p-xylene nitrile cov tshuaj tiv thaiv tshuab. Isophenonitrile yog ib qho ntawm cov khoom siv tseem ceeb ntawm broad-spectrum low-toxicity fungicides Chlorothalonil, thiab tseem tuaj yeem siv los tsim ntau cov kab mob thiab tshuaj tua kab: p.phenylphthalonitrile tuaj yeem siv los tsim cov tshuaj tua kab pyrethroid. Tsis tas li ntawd, M / p-phthalonitrile kuj tuaj yeem siv los ua cov nylon septum resin, isocyanate, polyimide, thiab lwm yam khoom siv hluavtaws. Txij li thaum lig 1990s, Shanghai tshawb fawb lub koom haum ntawm Petrochemical kev lag luam pib kawm thev naus laus zis ntawm pp-xylene roj theem nitrogen oxidation rau ppp-phthalonitrile thiab tau ua tiav plaub tiam ntawm catalysts, tiam tshiab ntawm catalysts yog NC-lV. Raws li cov catalyst saum toj no, Shanghai Kev Tshawb Fawb Lub Tsev Haujlwm ntawm Petrochemical Kev Lag Luam tau tsim cov txheej txheem ua tiav rau M / p-xylene ammoxidation thiab ua tiav lawv hauv kev lag luam.

Lub phiaj xwm tau txais tag nrho 9 qhov kev tso cai tsim tawm patents hauv tsev thiab txawv teb chaws, thiab yeej thawj qhov khoom plig ntawm Science thiab Technology Progress ntawm Petrochemical Federation, Tuam Tshoj Patent Excellence Award, thiab qhov khoom plig thib ob los ntawm Sinopec Patent Group.

◆ Kev ua haujlwm siab xaiv: Cov catalyst muaj kev hloov pauv siab thiab kev xaiv, thiab qhov hnyav tawm los ntawm lub cim tshiab ntawm NC-IV m / p-phthalonitrile catalyst tuaj yeem ncav cuag ntau dua 92%.

◆ Cov khoom siv thiab kev siv hluav taws xob hauv cov txheej txheem tsim khoom raug txo kom tsawg. Piv nrog rau cov thev naus laus zis qub, cov tshuaj tiv thaiv kub yog txo los ntawm 40 degree, qhov piv ntawm huab cua mus rau ammonia kuj txo, kev siv dej hauv cov tshuaj tiv thaiv ntawm cov khoom siv raw yog zam, thiab lub peev xwm thauj khoom ntawm cov catalyst yog qhov muaj zog dua. thawj thev naus laus zis, zoo txo ​​cov nqi tsim khoom. Los ntawm kev siv cov kev ua haujlwm nqaim nqaim zoo particle catalyst thiab kev ua haujlwm siab fluidized txaj, cov txheej txheem ntawm cov tshuaj tiv thaiv yog optimized, thiab qhov sib piv ntawm ammonia thiab qhov chaw ntawm cov txheej txheem cov tshuaj tiv thaiv yog txo kom zoo dua piv nrog cov tsoos thev naus laus zis thiab cov khoom pov tseg raug txo. .

◆ Zoo-tsim turbulent fluidized txaj reactor: Cov tsim tshwj xeeb tsim turbulent fluidized txaj reactor tuaj yeem ua tau zoo fluidization zoo thiab cov tshuaj tiv thaiv kev hloov pauv ntawm cov particle catalyst, thiab xyuas kom ruaj khov ntawm cov tshuaj tiv thaiv.

Cov yam ntxwv tseem ceeb ntawm M-xylene ammonia oxidation catalyst yog raws li nram no:

◆ Catalyst lub neej ntev: lub catalyst muaj kev ruaj ntseg zoo, thiab tag nrho cov kev hloov pauv rau cov ntawv thov kev lag luam tuaj yeem ncav cuag tsib xyoos lossis ntau dua.

◆ Kev ua tau zoo ntawm cov catalyst tau zoo dua qub. Cov txiaj ntsig ntawm M / p-phthalonitrile los ntawm qhov hnyav tuaj yeem ncav cuag ntau dua 92%.

Methanol vapor theem amination catalyst rau methylamine ntau lawm tau siv nyob rau hauv ntau tshaj 20 teeb ntawm industrial nroj tsuag rau ntau tshaj 50 lub sij hawm. Tus tshiab A-16 methylamine catalyst yuav ua tiav daim ntawv thov kev lag luam hauv xyoo 2020, thiab nws cov ntsuas kev ua tau zoo dua A-6A catalyst.

Cim npe nrov: ua tiav technology thiab catalyst rau m / p-xylene ammoxidation txheej txheem / p-xylonitrile, Tuam Tshoj ua tiav technology thiab catalyst rau m / p-xylene ammoxidation txheej txheem / p-xylonitrile manufacturers, lwm tus neeg, Hoobkas
