Deoxidize

Recycling thiab siv cov pa pa tawm hauv industrial

Cov pa tso pa tawm los ntawm kev tsim khoom lag luam muaj ntau cov khoom tseem ceeb, tab sis vim muaj O2.
Tam sim no, nws yooj yim tawg, ua rau muaj teeb meem kev siv dua tshiab. Piv txwv li, nyob rau hauv cov txheej txheem ntawm chlorohydrin ntau lawm ntawm propylene oxide, cov pa pa muaj li 50% propylene thiab propane, thiab lwm yam., nrog rau cov nqi rov qab ntau heev. Deoxidizer tuaj yeem tshem tawm cov pa seem hauv propylene thiab propane zoo.

High purity gas thiab tiv thaiv roj npaj

High-purity nitrogen yuav tsum muaj cov pa oxygen hauv cov pa kom tsawg dua 5 ppm, thiab kev tsim cov siab -purity nitrogen los ntawm cov nitrogen ntau yuav tsum tau deoxygenation.
Raws li kev ua ntawm deoxidizer, cov pa oxygen hauv siab -purity nitrogen tuaj yeem tsawg dua 0.1ppm. Nyob rau hauv cov nqe lus ntawm kev tiv thaiv roj, tshwj xeeb tshaj yog nyob rau hauv shipping cheeb tsam xws li loj loj integrated circuits, laser cov ntaub ntawv, optical fibers thiab aerospace cov ntaub ntawv, cov txheej txheem ntau lawm yuav tsum tau nqa tawm nyob rau hauv ib tug ultra- huv si ib puag ncig system. Piv txwv li, cov txheej txheem tsim khoom semiconductor yuav tsum tau txo cov pa oxygen hauv cov pa mus rau 1 ppm lossis qis dua, uas yuav tsum tau siv lub deoxidizer tsim nyog tshem tawm cov pa kom tau raws li qhov xav tau.

Syngas deoxygenation

Cov pa oxygen hauv syngas reacts nrog cov khoom carbonylation los tsim cov kua qaub uas inhibits cov tshuaj tiv thaiv carbonylation. Thiab oxidize lub cocatalyst los ua ib qho tsis yog -catalytic complex, txo cov tshuaj tiv thaiv. Ruding Nyob rau hauv cov txheej txheem ntawm octanol ntau lawm, thiaj li yuav tshem tawm carbonyl hlau thiab npib tsib xee carbonyl, yuav tsum tau npaj khoom tsim nyob rau hauv pem hauv ntej seem. Ib qho nyiaj ntawm cov pa oxygen, tab sis cov pa seem seem tuaj yeem yooj yim ua rau propylcarbonylation ntawm cov hlau muaj nuj nqis nyob rau theem tom ntej Catalyst deactivation. Txhawm rau tiv thaiv cov khoom siv hluav taws xob uas muaj txiaj ntsig zoo, cov ntsiab lus ntawm cov pa oxygen hauv cov khoom siv hluav taws xob yuav tsum tau tswj qis dua 1ppm, uas yuav tsum tau siv cov khoom siv deoxidation los nruab rau pem hauv ntej ntawm cov neeg tsim khoom.

Propylene deoxygenation thiab refining

Petrochemical polyethylene thiab polypropylene ntau lawm yuav tsum muaj cov pa oxygen hauv cov pa kom tsawg dua 0.1ppm.
Vim tias cov kab mob oxygen yuav hnov ​​​​mob nrog cov catalyst, cov haujlwm catalyst yuav txo qis. Nyob rau tib lub sijhawm, nws cuam tshuam nrog cov tshuaj hauv cov tshuaj tiv thaiv los tsim cov tshuaj resinous, uas thaiv cov catalyst pores thiab cov kav dej. Deoxidizers rau olefinrefining xav kom muaj kev cuam tshuam sab xws li olefin hydrogenation thiab oxidation tsis tuaj yeem tshwm sim, uas yuav tsum tau muaj kev ua tau zoo dua deoxidizers tus neeg sawv cev.
