Erthene (C₂H₄) sawv raws li cov tsim tawm tshaj plaws hauv ntiaj teb, nrog kev tsim ntau xyoo ntau tshaj 200 lab metric tons. Qhov kev tsis tau nyiaj hauv hydrocarbon ua haujlwm ua lub hauv paus rau suav tsis suav - los ntawm plastics rau cov tshuaj tiv thaiv. Cov chav tawg niaj hnub tuaj yeem ua tau txheej txheem 150,000 lub thoob / hnub tawm tsam kom zoo, ua tiav 800-900 degree.

Tsis ntev los no thev naus laus zis txhim kho hauv kev tsim khoom muaj xws li:

Oxidative Coupling of Mthohane (OCM) nrog 25% KWV YEEM

Electrochemical nrum pleb kev txo lub zog siv los ntawm 40%

Membrae sib cais technologies purifying ething ntws

Ethees tus yam ntxwv - cov qauv tsim ua kom nws ua rau:

Polymerization rau hauv polyethylene (60% ntawm kev siv thoob ntiaj teb)

Oxidation rau ethylene oxide (kev kho mob sterilant)

Halogenation rau pvc ntau lawm

Lub nrawm nrawm nrawm tau hloov kho kev lag luam kev lag luam, nrog peb cov nqi ntau lawm 30% qis dua naphtha}} raws txoj kev. Cov ntaub ntawv nthuav tawm muaj xws li - powered roj hlwb thiab carbon nanotube synthesis ntawm plasma {}} txhim kho decomposition.

Kev tawm dag, nrog cov tshuaj C2h6, yog Alkane tsuas yog suav txog ob cov roj ntsha atoms. Kev tawm suab yeej tau txuas ua ke los ntawm kev sib txuas lus. Qhov no txhais tau tias txhua tus pa roj atom nyob rau hauv lub ethan molecule yog ze txuas rau tsim qauv qauv. Hauv lub neej txhua hnub, kev coj tsis ncaj yog cov xim tsis muaj kob thiab tsw ntxhiab. Nws tuaj yeem ua rau tawg thaum raug hluav taws. Yog li ntawd, nws yuav tsum khaws cia thiab siv nrog kev saib xyuas zoo.

Cov roj no tsuas yog tau ua ib qho los ntawm - cov khoom ntawm cov roj nkev extraction lossis roj refining txheej txheem thiab tau siv dav hauv kev lag luam tshuaj. Kev tawm tsam yog tshwj xeeb yog qhov tshwj xeeb hauv kev lag luam petrochemical thiab feem ntau siv los ua cov khoom siv raw rau kev tsim cov tshuaj tiv thaiv kab mob. Raws li koj tuaj yeem xav txog, Ethylene yog qhov tseem ceeb ntawm cov plastics thiab cov khoom siv hluav taws xob. Tom qab cov khoom yas, tej zaum yuav muaj kev coj tsis ncaj.

Sib nrug ntawm nws qhov tseem ceeb hauv kev tsim khoom, cov tshuaj lom neeg ntawm kev coj ceev kuj muaj ntau haiv neeg sib txawv. Nws cov tshuaj lom neeg feem ntau suav nrog dawb radical tshua muaj, thiab cov kev tshuaj tiv thaiv nrog Halogen yog qhov tseem ceeb tshaj plaws. Tshwj xeeb tshaj yog thaum reacting nrog chlorine thiab bromine, lub decomposition ntawm ethane feem ntau tshwm sim los ntawm txoj saw kev loj hlob ntawm ethyl radicals. Thaum lub sijhawm no, halogenated ethane yuav tsim ntau cov khoom lag luam halogenated ntau, uas ntxiv rau qhov tseem ceeb ntawm kev coj ua hauv tshuaj lom neeg.
