Pambuyo pake, benzene/hydrobenzene yoyera itatsika mpaka 6000 yuan mark, motsogozedwa ndi kufewetsa kwabwino kwa mfundo zadziko, malingaliro a msikawo adasintha pang'ono, amalonda ena ndi kugula zinthu zapansi pamadzi, voliyumu yoyera ya benzene/hydrobenzene, idalimbikitsa kukwera kwamitengo, June 16, mtengo wa mafuta a benzene wa Shandong unali pafupifupi 6220 yuan/tani, kuwonjezeka kwa 80-140 yuan/ton. Anayala maziko a hydrobenzene rebound sabata ino.

Pakadali pano, msika womwe umayang'ana kwambiri pakukula kwa kagwiritsidwe ntchito ka styrene mphamvu, kuchepa kwa magwiridwe antchito a phenol komanso kuchuluka kwa zinthu zotuluka kunja kwa benzene.

1, kugwiritsa ntchito mphamvu zakutsika kwa styrene kukuyembekezeka kuwonjezeka

Kumayambiriro kwa malo opangira ma styrene akukonzekera kuyambiranso, kuphatikiza Zhejiang Petrochemical matani 600,000 a zida adayikidwa nthawi ya 15 koloko pa June 16, kuchokera ku China yopanga ma styrene ndikugwiritsa ntchito mphamvu zikuyembekezeka kuwongolera zonse. Kugwiritsira ntchito mphamvu kwa styrene kudzawonjezera kufunika kwa benzene koyera, kudzawonjezera kumwa kwa benzene koyera, koma pambuyo pa kuwonjezeka kwa styrene ntchito mlingo, m'pofunikabe kulabadira kunsi kwa mafananidwe a styrene, ngati kumunsi kwa styrene n'kovuta. kukwaniritsa kusintha kofananira, styrene imayang'anizana ndi zomwe zimaperekedwa ndikuchepetsa kufunikira, pambuyo pake, styrene imalowa pang'onopang'ono kutentha kwanthawi yayitali.

2, kutsika kwa phenol ketone opareshoni ikupitilira kuchepa

Posachedwapa mabizinesi akutsika a phenol ketone adayamba pamlingo wa 69%, mwezi-pa-mwezi -1%. Pakati pawo, panthawi yotseka ndi kukonza mayunitsi a Jiangsu Ruiheng, Shanghai Sisar ndi Gaoqiao Petrochemical phenol ketone mayunitsi, Shenghong kuyenga phenol ketone mayunitsi anali ndi ntchito zoipa, kotero phenol ketone ntchito mlingo anapitiriza kuchepa, kuchepetsa kumwa benzene koyera, ndi kupanga. ndemanga zoyipa pa benzene/hydrobenzene yoyera.

3, kutulutsa kwa benzene koyera ku China kukuyembekezeka kukwera

Kumapeto kwa nthawi yokonzekera kunja kwa nyanja, ndipo mphamvu ya octane yatha, benzene yoyera ya ku Asia iyenera kulowa mu China kuti igayidwe, ndipo akuyembekezeka kuti katundu wamtundu wa benzene achuluke, zomwe zidzapangitse kukwera kwa benzene yoyera. perekani, kuchokera pakuwona kwa mwezi ndi mwezi, kutengera kunja kapena kuchokera ku matani 200,000 mpaka matani 300,000 a sikelo.

Kuphatikiza apo, Hainan Refining ndi Chemical matani atsopano a 2.6 miliyoni a chakudya chosintha, CNOOC Huizhou matani atsopano okwana 1.3 miliyoni akusintha ma aromatics ndi disproportionation akuyembekezeka kuyikidwa muzakudya pambuyo pake, kuchuluka kwa zoweta za benzene koyera.

Pakanthawi kochepa, kuphatikiziranso kopanda kanthu kamodzi kumapeto kwa mwezi, tikuyembekezeka kuti mpweya wogula wa benzene/hydrobenzene uwongoleredwe, ndipo mtengo wa hydrobenzene ukhoza kukhazikika ndikuyambiranso, koma kutalika kwake ndi mphamvu ndi zochepa, chifukwa msika udakali mu nkhani zoipa, ndipo mzere wapakati ndi wautali umagwiritsidwa ntchito ndi malingaliro opanda kanthu.
