Txheej txheem cej luam
Muab cov yam ntxwv ntawm cov thee nplua nuj thiab cov roj tsawg hauv Suav teb, methanol-to-olefin (MTO) thev naus laus zis tau txais kev loj hlob sai nyob rau xyoo tas los no, thiab Sinopec SMTO yog thawj tus neeg muaj tswv yim 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-resistant catalyst", "fast fluidized bed react-regeneration process" thiab "MTO. high-efficiency sib cais txheej txheem ntawm olefin", thiab tsim methanol hloov dua siab tshiab cov tshuaj tiv thaiv thiab olefin sib cais ntawm tag nrho cov technologies.
Qhov project tau txais 260 Suav-tsim kev tsim khoom patents thiab 23 tau tso cai thoob ntiaj teb tsim 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, qhov kev tsim ntawm daim ntawv multistage pore catalytic cov ntaub ntawv thiab kev txhim kho cov txheej txheem tseem ceeb thev naus laus zis tau ua rau muaj kev cuam tshuam loj hauv kev lag luam thiab Coal Chemical tshiab. Kev lag luam academia.
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-regeneration txheej txheem. 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. Txoj kev tsim kho tshiab ntawm ob-theem regeneration technology raws li qhov ntws tau paub txog kev tswj xyuas meej ntawm catalyst carbon deposition.
High efficiency tshem tawm ntawm catalyst nplua hmoov nyob rau hauv cov tshuaj tiv thaiv-regeneration system. Cov tsim "tsis zoo siab suction" peb-spin separator thiab "multi-component superimposed" high-efficiency scrubber muaj qhov tshem tawm siab ntawm cov hmoov zoo hauv lub tshuab ntxhua khaub ncaws, uas daws qhov teeb meem cuam tshuam rau kev ua haujlwm ntev ntawm lub cuab yeej.
Cov txheej txheem tshiab rau kev ua haujlwm siab MTO olefin sib cais. Tsim ntau yam thev naus laus zis thiab cov txheej txheem sib cais xws li pre-deethane, C4 hydrocarbon rov qab ntawm ethylene, oxygen-muaj cov sib txuas tshem tawm, ethylene, propylene cov khoom muaj siab purity, superior rau zoo xws li txawv teb chaws sib cais technologies.
Kev koom ua ke ntawm MTO txheej txheem thiab naphtha chav cracking txheej txheem. Kev siv tau zoo ntawm MTO los ntawm cov khoom lag luam alkanes, kev siv methanol txo qis ntxiv, 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 hauv Zhongyuan Petrochemical ua tiav, kos npe tias Tuam Tshoj tau dhau los ua thawj lub teb chaws hauv ntiaj teb los ua tus tswv ntawm 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 plaws 3.6 lab tons / xyoo cog tau tsim nyob rau hauv ZhongTianhe thiab muab tso rau hauv ntau lawm hauv 2016, thiab 1.8 lab tons / xyoo cog tau tsim-hauv 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 hloov roj.
