Ngo-2023, intsingiselo iyonke yemarike yetoluene yaseTshayina yomelele, kwaye ukusebenza kwemarike yetoluene kuyancomeka ngenxa yokusebenza okusisiseko okuzinzileyo.

Kwikota yokuqala, ingqwalasela yothethathethwano lwemalike yetoluene yaya yaya phezulu, kwaye eyona nkxaso ilungileyo ibikukusetyenziswa okuzinzileyo koshishino lwepetroli. Ngokukodwa, ngoJanuwari, ikamva leoli ekrwada yamazwe ngamazwe yanyuka yaya phezulu, umgaqo-nkqubo wobhubhane wawukhululekile, kwaye icala lokubonelela lavulwa ngenxa yesixhobo sokungafani kwe-Daxie, kunye nomthamo wentengiso ye-toluene yangaphandle eMpuma China yancitshiswa ngeetoni ezingama-30,000, kunye neshishini. kulindeleke ukuba imarike yexesha elizayo ibe ntle, ixhasa imarike ye-toluene ukuba ibe ntle. Emva kokubuyela esixekweni emva kweholide Spring Festival ngoFebruwari, nangona ukuqokelela izibuko, ishishini petroli ngenkuthalo wathenga ummandla Shandong wakhokela ilizwe, kunye nommandla East China walandela Shandong; Ukongezelela, amanye amashishini asezantsi aye agcina kwaye aqala umsebenzi, kwaye ichweba liye laqala ukuya kwinqanaba lokugcina, okwenza i-toluene izinzile kwizinga eliphezulu. Ngo-Matshi, ngenxa yokuthengiswa kwempahla ye-toluene yi-Qingdao Lidong Foreign Trade Co., LTD., ukuthengiswa kweemarike kulindeleke ukuba kube nzima. Kwaye i-bankruptcy yeebhanki zaseYurophu kunye neMelika zinempembelelo enkulu kwingqondo yabaqhubi, okwenza ukuguquguquka kweemarike ze-toluene.

Imakethi ye-toluene yawa emva kokunyuka kwikota yesibini, kwaye inkxaso encomekayo yecala lokubonelela ikwi-intanethi, kodwa imfuno ebuthathaka iye yalicinezela kakhulu ixabiso. Ngo-Epreli, ishishini lepetroli lithenge ngokukhutheleyo, kwaye ukunyuka kwexabiso kwingingqi yaseShandong kwakhokelela ekunyukeni kwamaxabiso kwimimandla ejikelezileyo. Kwangaxeshanye, ifestile ye-arbitrage yase-Asia yaseMelika yavulwa, kwaye ukuthunyelwa kweemveliso ze-aromatics zaseMzantsi Korea e-United States kutsale umdla wentengiso. Ukususela ngoMeyi ukuya kuJuni, amashishini asekhaya e-toluene angena kwixesha eliphakathi lolondolozo, kwaye unikezelo lwehla kakhulu; Nangona kunjalo, amashishini ekhemikhali asezantsi kunye nepetroli asebenza ngokubanzi, kwaye ukulindela ngaphandle kwe-arbitrage yase-Asia kunye neMelika kuyadaniswa, ngoko ke ukunikezelwa okwethutyana ngaphandle kokugcinwa. Kwangaxeshanye, i-oscillation ebanzi ye-oyile ekrwada kunye neendaba zerhafu yokusetyenziswa ehlawuliswa kwiimveliso ezinxulumene ne-aromatics zigubungele imarike, isenza ukuba imarike ye-toluene ilumke.

Ukungena kwikota yesithathu yezinto ezilungileyo ezigxininisiweyo, amaxabiso emarike yetoluene kunyaka ophezulu aqhubekile ukuhlaziya. Okokuqala, ezinye iimveliso ezinevumba elimnandi lokurhafisa iibhutsi zerhafu ezisetyenziswayo, ezibekwe ngaphezulu kushishino lwepetroli ukunyuka kwemfuno yomthengi; Okwesibini, ifestile yokuthumela ngaphandle kwepetroli kunye ne-toluene ivuliwe, kwaye imfuno iyanda. Kwakhona, ixabiso lekamva leoli ekrwada lamazwe ngamazwe linyuke laya kutsho kwelona xabiso liphezulu ukusukela nge-12 kaNovemba ka-2022, linika umoya wenkxaso yorhwebo, kwaye emazantsi emarike ye-toluene ixhaswa kakuhle.

Kwikota yesine, iShandong Lianyi kunye neDaqing Longjiang Chemical disproportionation units ziye zasetyenziswa, kwaye itoluene yasetyenziswa njengezinto ezikrwada ukuvelisa ibenzene esulungekileyo, okubangele utshintsho olukhulu kunikezelo lwengingqi kunye nemfuno yemeko yetoluene, kunye nomahluko wexabiso phakathi i-toluene kunye ne-benzene ecocekileyo ibe nefuthe elibonakalayo ekuqalisweni kwamashishini.

Isishwankathelo, imarike ye-toluene ngo-2023 ibonisa ukunyuka kwe-oscillation phantsi kwe-interweaving yezinto ezintathu eziphambili zokubonelela, imfuno kunye nokwakhiwa kweendleko; Izinto ezimbi azibonakali kakuhle.
