S-APO Propylene Oxide Technology thiab Catalyst

Propylene oxide (PO) yog cov khoom siv raw rau kev tsim cov polyether polyols thiab, ntxiv, polyurethanes. S-APO propylene oxide tshuab yog raws li propylene, isopropylbenzene hydrogen peroxide (CHP), huab cua, thiab hydrogen ua raw khoom, los ntawm oxidation ntawm isopropylbenzene. Propylene epoxidation thiab dimethyl benzyl cawv (DMBA) hydrogen hydrolysis ntawm isopropylbenzene, isopropyilbenzene recycling los tsim propylene oxide. Txij li thaum xyoo 2003, lub koom haum Shanghai tau ua tiav kev tshawb fawb txog kev ua tiav cov txheej txheem thev naus laus zis rau S-APO synthesis ntawm PO, thiab ua tiav kev ua haujlwm siab titanium uas muaj mesoporous propylene epoxidation catalysts thiab dual-function DMBA hydrogenolysis catalysts nrog superhydrophobic zog. Raws li cov catalyst saum toj no, ib lub tshuab ntsuabPO pob tshuab (S-APO) nrog cov yam ntxwv ntawm kev lag luam atomic tau ua tiav tiav.

Qhov project tau txais 43 daim ntawv tso cai tsim khoom patents hauv Suav teb thiab yeej qhov khoom plig thib ob ntawm SINOPEC ProspectiveBasic Research Science Award.

S-APO propylene oxide thev naus laus zis yog ntsuab thiab ib puag ncig tus phooj ywg PO ua tiav txheej txheem thev naus laus zis nrog cov yam ntxwv ntawm kev lag luam ntawm cov tshuaj tiv thaiv atomic. Lub 150, 000 tons / xyoo PO industrial ua qauv qhia cog yuav tsim nyob rau hauv Tianjin Petrochemical Co., LTD. Nws cov yam ntxwv technical yog raws li nram no:

◆ Cov tshuaj tiv thaiv epoxidation muaj kev nyab xeeb thiab ua haujlwm tau zoo: propylene epoxidation cov tshuaj tiv thaiv thiab kev tswj hwm nrog ntau theem hauv series thiab tshem tawm cua sov ntawm theem; Qhov siab dua ntawm CHP raw cov ntaub ntawv thiab qis dua propylene / CHP piv tuaj yeem siv los txo kev siv hluav taws xob; Raws li qhov sib txawv reactivity ntawm catalyst lub neej voj voog, tsim nyog kev npaj ntawm reactor ib ntus tuaj yeem ua kom tiav tag nrho cov kev hloov pauv ntawm CHP thiab tshem tawm qhov kev pheej hmoo ntawm kev nyab xeeb.

◆ Kev ua haujlwm siab thiab txuag hluav taws xob ntawm hydrogenolysis cov tshuaj tiv thaiv kab mob: kev sib txuas zoo ntawm dewatering thiab hydrogenation ntawm dimethyl benzyl cawv tau tsim thiab ob txoj haujlwm PD-based hydrogenolysis catalyst tau tsim tiav. Raws li cov yam ntxwv ntawm bifunctional catalyst, ob-theem hydrogen hydrolysis txheej txheem tau ntse tsim los ua kom muaj kev sib koom siab siab.

xaiv thiab siab hloov pauv ntawm catalyst, thiab txo qhov poob ntawm isopropylbenzene.

◆ Cov txheej txheem ua kom zoo zoo thiab cov khoom zoo heev: organic acid enrichment -alkali ntxuav / dej ntxuav cov txheej txheem tshem tawm, ib feem me me ntawm cov tshuaj tiv thaiv kua siv cov khoom siv zoo alkali ntxuav / dej ntxhua kom zoo tshem tawm cov organic acids, txo qhov poob ntawm PO hauv cov txheej txheem ntxuav alkali. PO extractive distillation txheej txheem thiab extractant purification txheej txheem tau tsim los txhim kho lub purity ntawm circulating extractant thiab Po tawm los, thiab cov purity ntawm PO khoom tau mus txog ntau tshaj 99.99%.

S-APO propylene oxide pob suav nrog ob lub catalysts: superhydrophobic Ti / HMS epoxidation catalyst thiab bifunctionalPD-based hydrolysis catalyst.

Cov yam ntxwv tseem ceeb ntawm Ti / HMS epoxidation catalyst yog raws li nram no:

◆ Lub pob S-APO propylene oxide muaj ob lub catalysts: superhydrophobic Ti/HMS epoxidation catalyst thiab bifunctionalPD-based hydrolysis catalyst.

◆ Kev ua tau zoo ntawm epoxidation catalyst: Raws li lub hauv paus ntsiab lus ntawm bionics thawj zaug, Ti / HMS, muaj txiaj ntsig zoo titanium uas muaj mesoporous molecular iolite epoxidation catalyst nrog ultra ntxeem tau qauv thiab superhydrophobic zog rau oxidation ntawm propylene rau PO los ntawm CHP yog tsim los ntawm kev siv cov khoom superhydrophobic ntawm lotus nplooj thiab nws cov ultrananostructure thiab nto waxy txheej txheej txheem.

◆ Kev ua haujlwm siab: Ti / HMS epoxidation catalyst CHP kev hloov pauv mus txog ntau dua 99%.

◆ High selectivity: Ti/HMS epoxidation catalyst, PO thiab DMBA selectivity ntawm ntau tshaj 99%.

◆ Kev ruaj ntseg siab: Ti/HMS epoxide catalyst, lub neej ntawm 612 lub hlis (cov khoom zoo sib xws ntawm 4.5-9 hli).

◆ Ib puag ncig tus phooj ywg: cov catalyst tsis muaj cov khoom tsim kev puas tsuaj thiab cov khoom corrosive, thiab tsis ua phem rau ib puag ncig.

Cov yam ntxwv tseem ceeb ntawm bifunctional PD-based hydrolysis catalyst yog raws li hauv qab no:

◆ Kev ua haujlwm siab: DMBA hloov pauv tus nqi ntawm PD-based hydrolysis catalyst tau ua tiav ntau dua 99.9%.

◆ High selectivity: PD-based hydrogenolysis catalyst, isopropylbenzene selectivity mus txog ntau dua 99.5%.

◆ Kev ruaj ntseg siab: Kev siv dual-function PD-raws li hydrogen hydrolysis catalyst, lub neej ntawm ntau tshaj 2 xyoos, kom muaj lub sijhawm ntev ntawm kev ua haujlwm ruaj khov, tswj cov tshuaj tiv thaiv thaum ua haujlwm.

◆ Ib puag ncig tus phooj ywg: cov catalyst tsis muaj cov khoom tsim kev puas tsuaj thiab cov khoom corrosive, thiab tsis ua phem rau ib puag ncig.

Ua 150, 000 tons / xyoo S-APO propylene oxide cog hauv Tianjin Petrochemical. Xyoo 2022, S-APO propylene oxide thev naus laus zis yuav ua tiav daim ntawv tso cai ntawm 300, 000 tons / xyoo PO cog rau Zhenhai refining thiab tshuaj lom neeg kev lag luam.
