Ua tiav Technology thiab Catalyst rau Kev Npaj Benzonitrile Los Ntawm Ammoxidation Ntawm Toluene

Toluene ammoxidation rau benzonitrile thev naus laus zis siv toluene, ammonia, thiab huab cua ua cov khoom siv los tsim benzonitrile hauv ib kauj ruam dhau los ntawm cov tshuaj tiv thaiv ammoxidation gaseous. Benzonitrile ua cov kuab tshuaj tuaj yeem siv los tsim cov roj hmab nitrile, resin polymer, thiab txheej khoom. Nws kuj tseem siv tau rau hauv kev sib txuas ntawm benzene melamine, uas tuaj yeem txuas ntxiv rau hauv cov hlau coatings, cov phaj zoo nkauj, cov xim fluorescent, thiab lwm yam. Txij li xyoo 1990s, Shanghai Research Institute of Petrochemical Industry tau pib kawm cov thev naus laus zis ntawm benzene roj theem ammoxidation rau benzonitrile, thiab ua tiav kev tsim peb tiam 9 {9}N. BN{10}}98, thiab BN-10. Raws li cov catalyst saum toj no, ua tiav cov txheej txheem ntawm ammonia oxidation technologies rau toluene tau tsim thiab ua tiav hauv kev lag luam. Lub phiaj xwm tau txais tag nrho 5 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 PetrochemicalFederation, Tuam Tshoj Patent Excellence Award, qhov khoom plig thib ob hauv Shanghai Science thiab Technology Progress, thib ob khoom plig hauv Shanghai Patent Invention, thiab thawj khoom plig ntawm Shanghai kev lag luam-University-Research Institute.

◆ Kev ua haujlwm siab thiab kev xaiv: Cov catalyst muaj kev hloov pauv siab thiab xaiv, tiam tshiab ntawm BN-10 benzonitrile catalyst hnyav tawm los ntawm ntau tshaj 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, qhov ntsuas kub ntawm cov tshuaj tiv thaiv yog txo los ntawm 50 degree, qhov piv ntawm huab cua rau ammonia kuj raug txo, kev siv dej hauv cov tshuaj tiv thaiv ntawm cov ntaub ntawv raw yog zam, thiab lub peev xwm thauj khoom ntawm cov catalyst yog qhov muaj zog dua li qub thev naus laus zis, txo cov nqi tsim khoom. Los ntawm kev siv siab -kev ua tau zoo nqaim faib cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob ua haujlwm siab, cov txheej txheem ntawm cov tshuaj tiv thaiv tau ua kom zoo, thiab qhov sib piv ntawm ammonia thiab qhov chaw sib piv ntawm cov txheej txheem cov tshuaj tiv thaiv tau txo qis 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 hloov pauv ntawm cov khoom siv hluav taws xob zoo, thiab ua kom ruaj khov ntawm cov tshuaj tiv thaiv.

Lub ntsiab nta ntawm benzonitrile catalyst yog raws li nram no:

◆ Catalyst lub neej ntev: cov 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 yog txhim kho pom tseeb. Cov txiaj ntsig ntawm benzonitrile tau nce los ntawm 58.5wt% rau 92. 5wt% thaum hloov pauv ntawm toluene zoo ib yam, thiab kev xaiv ntawm cov catalyst tau txhim kho.

Txij li thawj qhov kev sim kev lag luam ntawm benzonitrile thev naus laus zis hauv xyoo 1997, nws tau siv rau hauv 3 lub lag luam thiab tau txais txiaj ntsig zoo ntawm kev lag luam.
