Technology thiab Catalyst rau Catalytic Deolefin hauv Aromatic Combined Unit

Paraxylene (PX) yog ib qho tseem ceeb ntawm cov organic raw khoom. uas feem ntau yog los ntawm cov tshuaj tsw qab ua ke cog siv cov roj hloov pauv raws li cov khoom siv raw. Cov kab olefin residue hauv cov roj hloov pauv yuav cuam tshuam rau PX cov txheej txheem tom ntej thiab cov khoom zoo. Cov txheej txheem siv molecular sieve nrog ib tug tshwj xeeb qauv raws li lub catalytic active chaw nyob rau hauv cov mob uas tsis yog-hydrogen thiab converts lub hard-rau-sib cais kab olefin mus rau hauv yooj yim sib cais high-boiling tebchaw thiab ces tshem tawm ntawm lub C{{4} } cov tshuaj tsw qab. Shanghai lub koom haum txuas ntxiv kawm txog cov thev naus laus zis no, thiab txuas ntxiv tsim DOT-100, D0T-200, thiab DOT-300 catalysts rau kev hloov kho cov khoom ntawm cov tshuaj tsw qab thiab lD{{9} }} catalysts rau isomerization units uas daws cov teeb meem ib puag ncig los ntawm kev tso tawm ntawm ib tug loj npaum li cas ntawm cov av dawb paug pov tseg nyob rau hauv PX ntau lawm units, thiab txhawb txoj kev loj hlob ntawm PXgreen ntau lawm technology.

Cov thev naus laus zis tau sau 12 daim ntawv tso cai tsim tawm hauv tsev thiab txawv teb chaws, thiab 1 qhov khoom plig thib ob ntawm lub xeev thiab tsoomfwv kev tsim khoom. Sinopec aromatic technology koom ua ke nrog cov catalyst tau yeej National Science thiab Technology Progress Special Award.

Cov thev naus laus zis ntawm catalytic olefin tshem tawm cov roj uas tsis yog hydroformated tsim los ntawm Shanghai lub koom haum siv cov kua-cov khoom ruaj ruaj lub txaj reactor tshem tawm cov kab olefin ntawm molecular sieve catalyst, uas yog ib qho kev ua haujlwm zoo rau kev txhim kho qhov zoo thiab kev ua haujlwm ntawm chav tsev aromatics. Nws cov yam ntxwv technical yog raws li nram no:

◆ Muaj zog siv tau: hloov ncaj qha ntawm cov av dawb, txheej txheem yooj yim.

◆ High olefin tshem tawm tus nqi: sib sib zog nqus tshem tawm cov kab olefin, lub neej voj voog ntev, kev tiv thaiv zoo ntawm cov dej ntws adsorbents thiab catalysts.

◆ Tus nqi qis: piv nrog cov txheej txheem av nplaum ib txwm siv thiab cov txheej txheem hydrogenation, tus nqi ntawm olefins tshem tawm tons ntawm cov khoom siv roj tsw qab yog txo los ntawm ntau dua 50%.

◆ Ib puag ncig tus phooj ywg: Piv nrog cov txheej txheem av nplaum ib txwm muaj, nws muaj qhov zoo ntawm kev ua haujlwm ruaj khov, tsis tshua muaj kev cuam tshuam sab nraud, tsis muaj hydrogen, txuas ntxiv dua, thiab cov catalyst siv yog tus phooj ywg.

Tam sim no, cov npe tseem ceeb ntawm catalytic decolefin catalysts suav nrog DOT-300 thiab lD0-01 decolefin catalysts, uas muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ruaj ntseg zoo, kev pabcuam ntev, thiab rov ua dua tshiab.

Hauv xyoo 2009, DOT-100 hloov kho cov roj deolefin thev naus laus zis tsim los ntawm Shanghai Lub Tsev Haujlwm tau tsim thawj zaug hauv Tianjin ceg cog.

Hauv 2015, D0T-200 hloov kho cov roj catalytic deolefintechnology tau siv rau hauv Sinopec Zhenhai Refining thiab chemical Branch, Gaogiao ceg, thiab lwm yam khoom siv, kom deb li deb, thev naus laus zis tau siv hauv 6 lub tuam txhab hauv tsev hauv 11 pawg. .

Xyoo 2019, lD0-01 diolefin catalyst tau ua tiav thawj zaug hauv isomerization unit ntawm lab-tuj PX cog hauv Hainan Refining thiab Chemical Company.

Hauv 2020, D0T-300 kev hloov pauv roj deolefin thev naus laus zis yuav raug siv rau hauv chav hloov kho ntawm Maoming ceg.

Hauv 2022, D0T-300 deolefin catalyst tau ua tiav hauv Yunnan Petrochemical hloov chaw cog.

Hauv 2023, D0T-300 diolefin catalyst tau ua tiav hauv Sinochem Quanzhou, Sichuan Petrochemical, Shanghai Petrochemical, thiab PetroChina Karamay Petrochemical-forming units.
