CTP Series Palladium-Carbon Hydrogenation Catalysts rau Terephthalic Acid

Vinyl acetate (VAC) yog ib qho tseem ceeb ntawm cov organic chemical raw khoom, dav siv nyob rau hauv kev tsim cov polyvinyl acetate, polyvinyl cawv, thiab ntxiv ua rau binder coatings, yas thiab fiber, ntaub ua, emulsions, resins, thiab films. Txoj kev tsim khoom ntawm ethylene acetate suav nrog cov txheej txheem acetylene ethylene txheej txheem, thiab cov txheej txheem ethylene tau dhau los ua txoj hauv kev tseem ceeb ntawm ethylene acetate ntau lawm hauv ntiaj teb. Lub sijhawm ntev, VAC thev naus laus zis thiab nws cov tub ntxhais catalyst tau monopolized los ntawm cov tuam txhab txawv teb chaws, tab sis txawv teb chaws catalysts muaj qhov tsis zoo xws li tus nqi siab, rhiab heev rau kev hloov pauv ntawm cov khoom siv raw, tsis zoo rau cov khoom siv raw cuam tshuam thiab luv catalyst ua haujlwm lub neej. Txhawm rau rhuav tshem cov tuam txhab txawv teb chaws ntawm vinyl acetate catalysts thiab cov khoom lag luam, txhim kho kev ua haujlwm ntawm catalysts, thiab ua kom muaj kev lag luam thiab kev hloov pauv ntawm patented technologies, Shanghai Institute tau cog lus rau thiab ua tiav cov txheej txheem ethylene tshiab vinyl acetate catalyst thiab lwm yam vinyl. acetate ntau lawm txheej txheem.

Lub catalyst yeej thawj qhov khoom plig ntawm Shanghai Science thiab Technology Progress thiab qhov khoom plig thib ob ntawm Sinopec Science thiab Technology Progress. Kev tsom mus rau cov thev naus laus zis tseem ceeb ntawm cov catalyst, ua ke nrog cov catalyst amplification thiab cov txheej txheem tshuaj tiv thaiv kev tshawb fawb, tag nrho ntawm ntau tshaj 60 Suav tau tso cai tsim patents suav nrog kev txhim kho catalystcarrier, catalyst innovation, tshuaj tiv thaiv txheej txheem thiab lwm yam thev naus laus zis tau txais.

Plaub qib ntawm CTV series vinyl acetate catalysts tau tsim, uas tuaj yeem siv rau cov txheej txheem sib txawv hauv cov nroj tsuag sib txawv. Cov yam ntxwv tshwj xeeb catalyst thiab cov txheej txheem txheej txheem rau cov ntawv thov kev lag luam tau qhia hauv cov lus hauv qab no.

Tam sim no, lub hom phiaj tseem ceeb ntawm vinyl acetate catalyst yog CTV-IV catalyst, uas muaj cov yam ntxwv ntawm siab dispersion ntawm palladium alloy thiab tsim nyog kev faib tawm ntawm palladium alloy particle loj. Cov txiaj ntsig ntawm daim ntawv thov kev lag luam qhia tias CTV-IV catalyst muaj qhov zoo ntawm qhov nruab nrab qhov chaw-lub sij hawm tawm los, siab nruab nrab xaiv thiab lub neej ntev thaum nws khiav ntawm ethylene acetate industrial cog. Cov kev ua tau zoo tau mus txog qib siab thoob ntiaj teb, tshwj xeeb tshaj yog lub neej catalyst, thiab kev xaiv catalyst yog nyob rau theem thoob ntiaj teb.

CTV series vinyl acetate catalyst tau siv nyob rau hauv 5 pawg ntawm ethylene acetic acid nyob rau hauv Daim ntawv thov kev vam meej ntawm ethylene cog hauv Sinopec system 100% Yog. Thaum lub sij hawm 20.21-20.23, ethylene txheej txheem ethylene acetate tshuab ua tiav daim ntawv tso cai ntawm Guangxi Huayi, Shandong Lianhong, Wanhua Chemical, thiab lwm yam lag luam.
