M'zaka zaposachedwa, Petroleum Resin zapezeka kuti dimers of dicyclopentadiene (CPD) ndi methylcyclopentadiene (MCPD) mu C9 sangagwiritsidwe ntchito bwino, Petroleum Resin kuchititsa kuwononga chuma. Popeza dicyclopentadiene zimagwiritsa ntchito kupanga mankhwala, mankhwala, Petroleum utomoni ndi utomoni mankhwala; methyl dicyclopentadiene imagwiritsidwa ntchito makamaka ngati zopangira popangira mafuta a rocket amphamvu kwambiri, mapulasitiki, Petroleum Resin ndi machiritso, Petroleum Resin ndipo ndiwothandiza kwambiri kwa anthu.
Chiyembekezo chogwiritsa ntchito mokwanira c9 petroleum resin ndi yayikulu. Mu Okutobala 2015, kuchuluka kwa utomoni wa petroleum kumawonjezeka mwezi ndi mwezi, Petroleum Resin makamaka chifukwa chazifukwa izi: Choyamba, Petroleum Resin ndi kuchepa kwa kutentha kwa nyengo, Petroleum Resin msika wapanyumba wamafuta amafuta adalowa munyengo yotsika kwambiri. kumwa. M'mweziwu, Petroleum Resin mtengo wa C5 wamtengo wapatali unali wotsika, ndipo kulandirira kunsi kwa mtsinje kunachepa. Kufunika kwa utomoni wa petroleum kunali kosakwanira, ndipo zogulitsa za opanga zidapitilirabe kutsika. Chifukwa chake, Petroleum Resin mtengo wotsika ndi mwayi waukulu wotumizira kunja. Kachitatu, Petroleum Resin kuchepa kwa kusinthana kwa RMB kupita ku Yuro kwathandiza kutumiza zinthu zapakhomo kunja.
Potengera momwe msika ukuyendera, dzinja ndi nyengo yotsika kwambiri pamsika wapanyumba wamafuta amafuta. Kuphatikiza apo, Petroleum Resin chifukwa chazovuta zachuma, pali zotsekera zambiri komanso zotsika. Chifukwa chake, msika umachepetsa kwambiri kukakamiza kwazinthu potumiza kunja. Mtengo wotsika wa C5 ulinso chinthu chabwino; Petroleum Resin the terminal and downstream shutdowns ndi zazikulu, Petroleum Resin kufunikira kwapakhomo kwa petroleum resin resin kuchulukira ndikuchepa, kotero kuti kuchuluka kwa kunja kupitirire kutsika.
