Txheej txheem cej luam
Muab cov yam ntxwv ntawm cov khoom siv roj nplua nuj thiab cov roj tsawg hauv Suav teb, methanol-rau-olefin (MTO) thev naus laus zis tau nce kev loj hlob sai nyob rau xyoo tas los no, thiab Sinopec SMTO yog thawj cov khoom ntiag tug kev txawj ntse muaj cai tag nrho cov txheej txheem thev naus laus zis. Tom qab ntau tshaj kaum xyoo ntawm kev tsim kho tshiab tas mus li, qhov project tau ua cov thev naus laus zis tseem ceeb tsim ntau yam thev naus laus zis xws li "nanosheet crystal multi-porous molecular sieve thiab siab hnav-} tiv thaiv catalyst", "fast fluidized bed react-regeneration process" thiab "MTO high-kev sib cais ntawm cov txheej txheem kev sib cais thiab kev sib cais ntawm ole ole", ntawm tag nrho cov technologies.
Qhov project tau txais 260 Suav -tso cai invention patents thiab 23 tso cai thoob ntiaj teb invention patents. Yeej thawj qhov khoom plig ntawm National Science thiab Technology Progress hauv 2017. Cov txheej txheem tshiab ntawm MTO cov tshuaj tiv thaiv tau npaj rau thawj zaug, kev tsim cov ntawv ntau qhov pore catalytic thiab kev txhim kho cov txheej txheem tseem ceeb thev naus laus zis tau ua rau muaj kev cuam tshuam zoo hauv kev lag luam thiab Kev Lag Luam Tshiab Coal Chemical Academy.
S-MTO tag nrho cov txheej txheem technology thiab catalyst
Raws li SAPO-34 cov khoom siv molecular sieve, MTO fluidized txaj catalyst nrog kev ua haujlwm siab thiab hnav tsis kam tau tsim, uas muaj cov pa roj carbon ntau ntawm cov ethylene + propylene thiab qis catalyst noj.
MTO ceev fluidized txaj cov tshuaj tiv thaiv- cov txheej txheem tsim dua tshiab. Cov tshuaj tiv thaiv qhov chaw ceev yog siab, lub reactor txoj kab uas hla yog me me, thiab cov tshuaj tiv thaiv efficiency yog zoo heev. Kev tsim kho tshiab ntawm ob -theem regeneration thev naus laus zis raws li qhov ntws tau paub txog kev tswj hwm ntawm catalyst carbon deposition.
Kev tshem tawm tau zoo ntawm catalyst nplua hmoov hauv cov tshuaj tiv thaiv- rov tsim dua tshiab. Cov tsim "tsis zoo siab suction" peb -spin separator thiab "multi-component superimposed" high-scrubber efficiency muaj qhov tshem tawm siab ntawm cov hmoov zoo hauv cov tshuaj txhuam hniav, uas daws qhov teeb meem uas cuam tshuam rau lub sijhawm ntev - kev ua haujlwm ntawm lub tshuab.
Cov txheej txheem tshiab rau siab -kev ua tau zoo MTO olefin sib cais. Tsim ntau yam thev naus laus zis tseem ceeb thiab cov txheej txheem sib cais xws li ua ntej-deethane, C4 hydrocarbon rov qab ntawm ethylene, oxygen- muaj cov khoom siv tshem tawm, ethylene, propylene cov khoom muaj purity siab, zoo dua li kev sib cais txawv teb chaws.
Kev koom ua ke ntawm MTO txheej txheem thiab naphtha chav cracking txheej txheem. Kev siv MTO kom zoo los ntawm -cov khoom alkanes, kev siv methanol raug txo kom tsawg, thiab kev hloov pauv thiab kev lag luam ntawm cov cuab yeej tau txhim kho.
Popularization thiab Daim Ntawv Thov
Xyoo 2011, 600,000 ton / xyoo cog tau tsim nyob rau hauv Zhongyuan Petrochemical ua tiav, kos npe tias Tuam Tshoj tau los ua thawj lub teb chaws hauv ntiaj teb los ua kom tiav tag nrho cov txheej txheem ntawm MTO thev naus laus zis nrog kev ywj pheej cov cuab yeej cuab tam, lub ntiaj teb loj tshaj 3.6 lab tons / xyoo cog tau tsim nyob rau hauv ZhongTianhe thiab muab tso rau hauv kev tsim khoom hauv xyoo 2016, thiab xyoo 2016. Zhongan United Coal Chemical thiab muab tso rau hauv ntau lawm hauv 2019.
Txoj haujlwm muaj txiaj ntsig tseem ceeb ntawm kev lag luam thiab S-MTO ua tiav cov txheej txheem thev naus laus zis tau mus txog qib kev coj ua thoob ntiaj teb. Nws tau txhawb nqa kev tsim kho thev naus laus zis ntawm kev siv cov thee huv hauv Suav teb thiab ua rau kev ua haujlwm thev naus laus zis ntawm kev tsim cov olefin los ntawm cov thee es tsis txhob siv roj.
