Ob txoj kev ua haujlwm rau maleic anhydride yog dab tsi?
Kev sib piv ntawm ob txoj kev ua haujlwm
Cov txheej txheem tsim khoom ntawm Maleic Anhydride feem ntau suav nrog benzene oxidation thiab n-butane oxidation technologies hais txog cov khoom siv raw. Kev sib piv ntawm benzene oxidation thiab n-butane oxidation hais txog cov txheej txheem:
Cov txheej txheem ntws: Ob txoj kev muaj cov txheej txheem ntws zoo sib xws; qhov sib txawv tseem ceeb yog nyob rau hauv cov catalyst.
Kev paub txog thev naus laus zis: Ob qho thev naus laus zis no yeej paub tab heev. Cov chaw tsim khoom txawv teb chaws feem ntau siv txoj kev n-butane, thaum cov chaw tsim khoom hauv tsev feem ntau siv txoj kev benzene.
Txoj kev n-butane ua tus qauv kev loj hlob: Los ntawm qhov kev xav ntawm kev txhim kho thev naus laus zis txawv teb chaws, kev lag luam maleic anhydride thoob ntiaj teb feem ntau siv cov txheej txheem n-butane. Yog li ntawd, qhov sib piv ntawm n-butane-raws li peev xwm tsim khoom txuas ntxiv mus ntxiv. Cov peev txheej n-butane txawv teb chaws muaj ntau, thiab 100% ntawm cov chaw tsim khoom tshiab siv txoj kev n-butane. Cov txheej txheem tsim khoom n-butane hauv Tebchaws Europe tau suav txog 89% ntawm cov peev xwm tsim khoom maleic anhydride tam sim no, thaum pib ua tiav kev hloov pauv txoj hauv kev raw khoom. Hauv Suav teb, vim muaj cov peev txheej coking benzene ntau los ntawm cov khoom siv tshuaj lom neeg thee, cov txheej txheem tsim khoom maleic anhydride raws li benzene suav txog 90% ntawm lub teb chaws tag nrho cov peev xwm tsim khoom maleic anhydride.
