Kub Cour Tar
Kev kub kub-kub thee yog ib qho los ntawm kev siv tau los ntawm qhov kub qhuav distillation ntawm cov thee. Nws yog cov kua roj oily dub nrog cov ntxhiab tsw tshwj xeeb. Lub hauv paus tseem ceeb yog cov ntxhiab hydrocarbons thiab cov organic sib sau muaj cov pa, nitrogen, lossis leej faj. Tom qab ua ntej distillation, cov feem ua haujlwm xws li lub teeb roj, roj Phenol, tshuaj ntxuav roj, thiab cov roj muaj zog tuaj yeem tau los ntawm txoj kev distillation; Cov feem ntau li cov roj teeb, cov roj hauv nruab nrab, roj hnyav, roj muaj peev xwm tuaj yeem tau txais cov qauv sib txawv; Cov distillation residue yog asphalt. Kev ua txuas ntxiv thiab ua kom zoo dua ntawm cov feem saum toj no tuaj yeem ua rau cov khoom siv rawes, thiab lwm yam, cov ntaub ntawv tawg, cov khoom tawg, hluavtaws, lossis cov txuj lom.
Taw qhia rau cov duab ntawm cov tar thee
Cov tar nyob rau hauv chav sov yog cov kua av uas muaj kuab heev, thiab kub ntawm cov coking yog qhov siab, xws li 1.120g / cm3. Mas suav txog polyciclic aromatic sib txuas, muaj tsawg cov ntsiab lus ntawm alkylatics, ntau heal boiling point, thiab zoo thermal ruaj khov. Its components have a higher content of naphthalene, while the relative content is relatively low, mainly including 1-methylnaphthalene, 2-methylnaphthalene, acenaphthene, fluorene, oxyfluorene, anthracene, phenanthrene, carbazole, anthracene, quinoline, pyrene, etc.
Kev ua tshuab ntawm cov khoom
Cov yam ntxwv ntawm txhua feem ntawm tar yog txawv, tab sis muaj ntau cov khoom siv nrog cov khoom zoo sib xws. Nws yog qhov tsim nyog los ua ntej siv cov hau kev distillation los txiav ntau yam feem, xws li Phenol, Naphthalene, Anthracene, thiab lwm yam
Cov khoom siv ib leeg rho tawm yog cov khoom siv muaj nyob rau hauv cov feem sib piv thiab sib cais siv lub cev thiab sib cais.
Lub feem ua ntej 170 ℃ yog lub teeb roj; Qhov feem ntawm 170-210 ℃ yog feem ntau cov roj phebolic roj; Lub ntsiab feem ntawm 210 ~ 230 ℃ yog cov roj naphtalene; Lub distillate ntawm 230-300 ℃ yog feem ntau ntxuav roj; Qhov feem ntawm 280-360 ℃ yog cov roj txawm anthracene xwb; Qhov feem ntawm 280-360 ℃ yog cov roj txawm muaj hluav taws xob; Thawj zaug npau npau npau npau ntawm anthracene roj feem yog 310, thiab nws yog 400 ℃ thaum distilling 50%
Khoom Qhia Khoom
Coal tar yog ib qho ntawm cov khoom tseem ceeb hauv kev lag luam coking, cov nyiaj txiag rau kwv yees li 3% rau 4% ntawm cov thee. Nws muaj pes tsawg leeg yog qhov nyuaj heev, thiab feem ntau, nws yog tsim ntawm cov thee
TAR kev lag luam tshwj xeeb hauv kev sib cais, huv, thiab kev siv. Ntau cov zauv feem ntawm tar tuaj yeem txuas ntxiv ua kom tiav cais ntau yam khoom. Tam sim no, cov khoom lag luam tseem ceeb muaj xws li:
(1) Naphthalene yog siv los tsim cov phthalic anhydride rau kev tsim cov khoom siv los ntawm cov resins, engineering plastics, thiab dyes. Siv rau xim thiab tshuaj.
(2) Phenols thiab lawv cov hom phooj ywg yog siv los tsim cov hluavtaws fibers, kev ua kom zoo, tshuaj tua kab, cov tshuaj tsuag, roj nruab nrab, thiab lwm yam.
(3) Anraquinone roj, hluavtaws kneading tus neeg saib xyuas, thiab cov xim ua los ntawm qhov tsis muaj sia.
(4) Phenanthrenen yog ib tug oorer ntawm kev muaj hwj chim, thib ob rau naphthealene hauv cov ntsiab lus, thiab muaj ntau yam kev siv. Vim nws cov txiaj ntsig siab, nws tseem xav tau kev txhim kho ntxiv thiab kev siv.
(5) Carbazole yog ib qho khoom siv tseem ceeb rau kev ua kom tuag, plastics, thiab tshuaj tua kab.
(6) Asphalt yog ib qho seem ntawm tar distillation, sib xyaw ntawm ntau yam polycyclic polymer tebchaw. Siv rau kev ua cov txheej ru tsev, noo noo-pov thawj txheej, kev siv, thiab ntau lawm
Asphalt Coke thiab hluav taws xob rauv electrodes, thiab lwm yam.
