Txheej txheem cej luam
Tam sim no, Tuam Tshoj lub refinery catalytic cracking, steam cracking thiab thee tshuaj MTO units yog nplua nuj nyob rau hauv by-product carbon quaternary kev pab cuam, thiab domestic carbon quaternary chemical siv yog deb tshaj li ntawm lub teb chaws tsim. Muaj cov lej ntawm 1,3-butadiene hauv C-4 feem tom qab rho tawm lossis ether, thiab nws txoj kev sib koom siab siab tuaj yeem ua rau lub cev tsis ua haujlwm sai ntawm cov khoom siv hluav taws xob xws li butene-1 polymerization, polymerization rau alkylatedoil, catalytic cracking ntawm C-4 rau propylene thiab olefin disproportionation, uas cuam tshuam rau kev ruaj ntseg ntawm theunit thiab ntxiv cuam tshuam rau kev siv tshuaj lom neeg ntawm C-4 cov peev txheej. Yog li ntawd, txoj kev loj hlob ntawm kev xaiv hydrogenation catalyst uas tsuas yog hydrogenates trace butadiene tab sis tsis hydrogenate siab cov ntsiab lus butene-1 / qis isomerization yog cov thev naus laus zis tseem ceeb kom paub txog kev siv nyiaj ntau ntxiv ntawm C4 cov peev txheej.
Txij li xyoo 2016, lub koom haum Shanghai tau cog lus rau kev tshawb nrhiav thiab kev tsim kho ntawm C-4 hydrogenation catalyst, thiab tau tsim SHB-01 catalyst nrog cov tswv cuab ywj pheej ywj pheej los hloov mus rau highspace ceev C-4 hydrogenation xaiv hydrogenation, ua tiav daim ntawv thov kev lag luam, txhawb kev ua haujlwm zoo thiab ua haujlwm tau zoo, thiab tseem ceeb heev los txhim kho kev siv C-4 cov peev txheej.
Qhov project tau txais tag nrho ntawm 8 Suav tso cai tsim khoom patents.
Kev xaiv hydrogenation ntawm C-4 feem ntau Saib xyuas rau kev tshem tawm butadiene
Lub tshuab thev naus laus zis ntawm C-4 feem yog tshem tawm cov kab butadiene impurities hauv cov ntaub ntawv raw los ntawm cov kua theem hydrogenation, thiab nws cov yam ntxwv kev ua tau raws li hauv qab no:
◆ Cov khoom siv raw muaj ntau yam kev siv, thiab tuaj yeem siv rau hauv catalytic cracking, steam cracking thiab thee chemical MTO thiab lwm yam plaub feem carbon raw cov ntaub ntawv.
◆ Cov ntsiab lus butadiene nyob rau hauv cov khoom siv raw yog tsim rau ntau yam, thiab cov ntsiab lus butadiene ntawm 50ppm thiab 1.5wt% muaj kev tshem tawm zoo.
◆ Tag nrho cov kua theem cyclic hydrogenation txheej txheem, butadiene tshem tawm qhov tob yog siab. 1-butene muaj isomerism qis thiab poob qis.
◆ Catalyst cov tshuaj tiv thaiv txo cov tshuab, hydrogenation selectivity siab, butadiene tuaj yeem raug tshem tawm mus rau theem kab mob.
Daim duab daim ntawv thov ntawm Selective Hydrogenation ntawm C-4 Fraction
C4 feem xaiv hydrogenation catalyst
Daim ntawv thov kev lag luam ntawm C4 xaiv hydrogenation catalyst yog SHB01, cov khoom tseem ceeb yog raws li hauv qab no:
◆ Kev ua haujlwm siab, kev xaiv siab: Nyob rau hauv cov tshuaj tiv thaiv me me, cov ntsiab lus butadiene hauv cov khoom siv tshuaj tiv thaiv hydrogenation tsawg dua 8ppm, poob ntawm 1-butene ntawm kev xa tawm tsawg dua 2.5%, thiab tag nrho hydrogenation thiab isomerization tus nqi qis.
◆ High stability: Shell transfer type specific structure catalyst, inhibit polymerization and other side reactions, strong poison resistance, inhibit the loss of active components, catalyst life >5 xyoo.
◆ Ib puag ncig tus phooj ywg: Cov catalyst tsis muaj cov khoom ua rau muaj kev puas tsuaj thiab corrosive, tsis muaj kuab paug rau ib puag ncig, thiab yooj yim los daws.
Popularization thiab Daim Ntawv Thov
Thaum lub Tsib Hlis 2017, SHB-01 catalyst tau siv nyob rau hauv 74, 000 tons / xyoo 1# MTBE 1-butene unit ntawm Sinopec Shanghai Petrochemical Co., LTD., nrog kev ua haujlwm ruaj khov thiab zoo heev khoom zoo.
