Txheej txheem cej luam
Halogenated benzonitrile yog tsim los ntawm ammonia oxidation ntawm toluene halogenated toluene, ammonia, thiab huab cua-hom halogenated benzonitrile cov khoom yog O/p-chlorobenzonitrile, 0/p-bromobenzonitrile, 2, 4-dichloro benzonitrile, 6-dichloro benzonitrile, thiab lwm yam. 0-chlorobenzonitrile tuaj yeem siv rau hauv kev tsim cov azo disperse dyes, thiab tseem yog ib qho ntawm cov khoom siv raw rau kev sib xyaw ntawm Sartan antihypertensive tshuaj thiab ntau yam tshuaj tua kab mob. P-chlorobenzonitrile tuaj yeem siv rau hauv kev sib xyaw ntawm cov xim siv dav thiab cov khoom siv lead ua kua; Ob peb lwm yam khoom yog siv nyob rau hauv synthesis ntawm kws tshuaj, tshuaj tua kab, thiab kua siv lead ua zaub cov ntaub ntawv. Txij li thaum xyoo 1990s lig, Shanghai Kev Tshawb Fawb Kev Lag Luam Petrochemical tau pib kawm cov thev naus laus zis ntawm roj theem ammoxidation ntawm toluene halogenated benzonitrile los tsim cov halogenated benzonitrile thiab ua tiav kev tsim cov halogenated benzonitrile catalyst raws li saum toj no catalyst, Shanghai Research Institute petrochemical kev lag luam tau tsim ib tug tiav set. ntawm halogenated toluene ammoxidation thev naus laus zis thiab ua tiav cov ntawv thov kev lag luam.
Qhov project tau txais 13 lub tsev tsim khoom tsim thiab txawv teb chaws, yeej thawj qhov khoom plig hauv Kev Tshawb Fawb thiab thev naus laus zis ntawm Petrochemical Federation, ChinaPatent Excellence Award, thiab lwm yam.
Ua tiav txheej ntawm ammonia oxidation tshuab ntawm toluene halide
Kev ua haujlwm siab thiab kev xaiv: Cov catalyst muaj kev hloov pauv siab thiab kev xaiv, thiab qhov hnyav tawm los ntawm cov tiam tshiab halogenated benzonitrile catalyst tuaj yeem ncav cuag ntau dua 87%.
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 40 degree, qhov piv ntawm huab cua mus rau ammonia kuj txo, kev siv dej hauv cov khoom siv raw khoom yog zam, thiab lub peev xwm thauj khoom ntawm cov catalyst yog qhov muaj zog ntau dua li cov khoom siv raw. 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 high-efficiency fluidized txaj, cov txheej txheem ntawm cov tshuaj tiv thaiv yog optimized, thiab cov pa oxygen ratio thiab qhov chaw qhov piv ntawm cov txheej txheem cov tshuaj tiv thaiv yog txo kom zoo piv nrog cov tsoos technology, thiab cov pov tseg. tso tawm yog 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 khoom uas npaj los ntawm cov txheej txheem muaj siab purity, tsawg los ntawm cov khoom, thiab cov nqi uas tsis muaj refining, uas zoo txhim kho cov kev sib tw ntawm Tuam Tshoj nyob rau hauv lub teb ntawm cov khoom, thiab cov kev qhia muaj feem xyuam rau lub thoob ntiaj teb ua theem.
Toluene halide ammoxidation catalyst
Cov yam ntxwv tseem ceeb ntawm ammoxidation ntawm toluene halide yog raws li nram no:
◆ Lub neej ntev ntawm catalyst: lub catalyst muaj kev ruaj ntseg zoo, thiab tag nrho cov kev hloov pauv rau kev lag luam tuaj yeem ncav cuag ntau tshaj plaub xyoos.
◆ Kev ua tau zoo ntawm cov catalyst tau zoo dua qub. Cov txiaj ntsig ntawm halogenated benzonitrile los ntawm qhov hnyav tuaj yeem ncav cuag ntau dua 87%. Piv nrog rau cov thev naus laus zis qub, cov txiaj ntsig tau nce ntau dua 20 feem pua ntawm cov ntsiab lus thiab lub neej kev pab cuam ntawm cov catalyst tau nce 8 zaug.
Kev txhawb nqa thiab kev thov
Txij li thawj qhov kev sim kev lag luam ntawm halogenated benzonitrile thev naus laus zis hauv 2000, nws tau siv rau hauv ntau lub tuam txhab tsim khoom, thiab muaj ntau yam sib txawv halogenated benzonitrile cov khoom tsim muaj peev xwm, tag nrho cov peev txheej ntawm cov khoom cog ntau tshaj 30,000 tons. / xyoo, thiab tau ua tiav cov txiaj ntsig kev lag luam siab.
