Kutentha kwambiri malasha
Njira Yopanga Zopangira Zamalonda
Blash-kutentha roma ndi cholembera kuchokera ku kutentha kwambiri kwodalitsa kwa malasha. Ndi mafuta akuda ndi fungo lapadera. Zigawo zikuluzikulu ndi ma hydrocarbons ndi zopangira zinthu zachilengedwe zimakhala ndi mpweya, nayitrogeni, kapena sulufule. Pambuyo dismillation yoyambirira, tizilombo tosaka mafuta, mafuta a pherothalene, kuchapa mafuta, ndipo mafuta a anthracene amatha kupezeka ndi njira yopitilira nthawi; Zipilala monga mafuta opepuka, mafuta olemera, mafuta olemera, ndipo mafuta a anthracene amatha kupezeka pogwiritsa ntchito njira yochepetsetsa; Sukulu yotsalira ndi asphalt. Kukonzanso magawo omwe ali pamwambawa kumatha kupereka benzenes, phenols, naphthalene, ma phenanthre, ma procridical, plactics, zonunkhira, kapena zonunkhira.
Mawu oyambira mawonekedwe a phula la malasha
Tala wa malasha kutentha kwa firiji ndi madzi akuda akuwoneka bwino, komanso kuchuluka kwa phula lamadzi otentha kwambiri opangidwa ndi ophika ndi okwera kwambiri, kuyambira 1.220g / masentimita / masentimita / masentimita / masentimita. Makamaka opanga ma polycyclic owerengeka, osawerengeka a alkyl armatics, zokulirapo zowiritsa zowiritsa, komanso kukhazikika kwa mafuta. Zida zake zimakhala ndi zochuluka za Naphthalene, pomwe zokhudzana ndi zotsika zili zochepa, makamaka methylnale, acerune, carceralne, aceracene, quoline, pyrece, etc.
Tekinologyology yokonza
Mphamvu iliyonse ya phula ndi yosiyana, koma pali zinthu zambiri zopangidwa ndi zinthu zomwezo. Ndikofunikira kugwiritsa ntchito njira zoyambira kudula tizigawo osiyanasiyana, monga phenol, naphthalene, anthraracene, etc
Zogulitsa zobwezeretsedwanso zimakhazikika m'magawo ofanana ndikusiyananso kugwiritsa ntchito njira zathupi ndi mankhwala.
Kachigawo chisanachitike 170 ℃ ndi mafuta opepuka; Kaquera pa 170-210 ℃ makamaka mafuta a phenolic; Gawo lalikulu pa 210 ~ 230 ℃ ndi mafuta a naphthalene; The Dificial pa 230-300 ℃ amasambitsa mafuta ambiri; Gawo la 280-360 ℃ makamaka mafuta a anthrararace; Kachigawo ka 280-360 ℃ ndi mafuta a anracerace; Choyimira choyambirira chowotcha cha anthracene ndi 310 ℃, ndipo ndi 400 ℃ posiya 50%
Cholinga chogulitsa
Bor malasha ndi chimodzi mwazinthu zofunikira pakuphika, kumawerengera pafupifupi 3% mpaka 4% ya malasha oikidwa. Kapangidwe kake ndi kovuta kwambiri, ndipo nthawi zambiri, kumapangidwa ndi malasha
Makampani opanga a phula amaphunzitsira popatukana, kuyeretsa, ndi kugwiritsidwa ntchito. Zigawo zingapo za phula zimatha kukonzedwa kuti zisaletse zinthu zosiyanasiyana. Pakadali pano, zinthu zazikulu zoyambitsidwa ndi:
. Chogwiritsidwa ntchito pojambula ndi mankhwala.
.
.
. Chifukwa cha zokolola zake zambiri, zimafunikirabe chitukuko komanso kugwiritsa ntchito.
(5) Carbazole ndi zinthu zofunika kwambiri za utoto, pulasitiki, ndi mankhwala ophera tizilombo.
. Ntchito yopanga zokutira za padenga, zigawo zogwirizana, zomangamanga, zomanga pamsewu, ndi kupanga
Asphalt coke ndi ntchentche ya electrodes, etc.
