Ngowama-2023, umkhwa uwonke wemarike ye-toluene yaseTshayina unamandla, kwaye ukusebenza kwemarike ye-toluene kuyancomeka ngenxa yokusebenza okuzinzileyo okusisiseko.

Kwikota yokuqala, ingqwalasela yengxoxo yemarike ye-toluene yenyuka, kwaye inkxaso ephambili eluncedo yayikukusetyenziswa okuzinzileyo kweshishini lepetroli. Ngokukodwa, ngoJanuwari, ikamva le-oyile ekrwada yamazwe ngamazwe yenyuka, umgaqo-nkqubo wobhubhane wawukhululekile, kwaye icala lokubonelela lavulwa ngenxa yesixhobo seDaxie disproportionation, kwaye umthamo wentengiso yangaphandle ye-toluene eMpuma China wehliswa ngeetoni ezingama-30,000, kwaye eli shishini lalilindele ukuba imakethi yexesha elizayo ibe ntle, ixhasa imakethi ye-toluene ukuba ibe ntle. Emva kokubuyela esixekweni emva kweholide yeSpring Festival ngoFebruwari, nangona izibuko laliqokelelene, imboni yepetroli yathenga ummandla waseShandong ngenkuthalo, kwaye ummandla waseMpuma China walandela iShandong; Ukongeza, amanye amashishini asezantsi aye eqokelela kwaye eqala umsebenzi, kwaye izibuko liqalile ukuya kwinqanaba lokugcina, okwenza i-toluene izinze kwinqanaba eliphezulu. NgoMatshi, ngenxa yokuthengiswa kwempahla ye-toluene yiQingdao Lidong Foreign Trade Co., LTD., kulindeleke ukuba unikezelo lwemarike lube luncinci. Kwaye ukubhanga kweebhanki zaseYurophu naseMelika kunempembelelo enkulu kwindlela abacinga ngayo abaqhubi, nto leyo eyenza ukuguquguquka kwemarike ye-toluene kube lula.

Imarike yetoluene yehle emva kokunyuka kwikota yesibini, kwaye inkxaso entle yecala lokubonelela isekwi-intanethi, kodwa imfuno ebuthathaka iye yanciphisa ixabiso kakhulu. Ngo-Epreli, ishishini lepetroli lathenga ngokukhutheleyo, kwaye ukunyuka kwamaxabiso kummandla waseShandong kwakhokelela ekunyukeni kwamaxabiso kwimimandla engqongileyo. Kwangaxeshanye, i-arbitrage yase-Asia-American yavulwa, kwaye ukuthunyelwa kweemveliso ze-aromatics zaseMzantsi Korea e-United States kwatsala ingqalelo yemarike. Ukususela ngoMeyi ukuya kuJuni, amashishini e-toluene asekhaya angene kwixesha lokugcinwa eliphakathi, kwaye ukubonelela kwehla kakhulu; Nangona kunjalo, amashishini eekhemikhali kunye nepetroli asezantsi ngokubanzi ayasebenza, kwaye ulindelo lokuthumela ngaphandle kwe-arbitrage yase-Asia naseMelika luyaphoxeka, ngoko ukubonelela akukho kugcinwa okwethutyana. Kwangaxeshanye, ukuxinana okukhulu kweoyile ekrwada kunye neendaba zerhafu yokusetyenziswa ehlawuliswa kwiimveliso ze-aromatics ezinxulumene noko kugqume imarike, okwenza imarike yetoluene ibe luqaphelo.

Ukungena kwikota yesithathu yezinto ezintle ezigxile kwizinto ezidityanisiweyo, amaxabiso emarike ye-toluene kunyaka ophakamileyo aqhubeke nokuhlaziya. Okokuqala, ezinye iimveliso ezinuka kamnandi zokuhlawulisa irhafu yokusetyenziswa, zibekwe phezu kokunyuka kwemfuno yabathengi kushishino lwepetroli; Okwesibini, ifestile yokuthumela ipetroli kunye ne-toluene ngaphandle iyavulwa, kwaye imfuno iyakhula. Kwakhona, ixabiso le-oyile ekrwada yamazwe ngamazwe lenyuke laya kwixabiso eliphezulu ukusukela nge-12 kaNovemba 2022, linika umoya wenkxaso yeempahla, kwaye umgangatho wemarike ye-toluene uxhaswa kakuhle.

Kwikota yesine, iiyunithi zeShandong Lianyi kunye neDaqing Longjiang Chemical disproportionation zaqaliswa ukusebenza, kwaye i-toluene yasetyenziswa njengezinto zokwenza imveliso ye-benzene ecocekileyo, nto leyo eyabangela utshintsho olukhulu kwimeko yokubonelela kunye nemfuno ye-toluene yengingqi, kwaye umahluko wamaxabiso phakathi kwe-toluene kunye ne-benzene ecocekileyo waba nefuthe elikhulu ekuqaliseni amashishini.

Ngamafutshane, imakethi yetoluene ngo-2023 ibonisa ukunyuka kokuguquguquka phantsi kokudibana kwezinto ezintathu eziphambili zokubonelela, imfuno kunye nokwakheka kweendleko; Izinto ezimbi azibonakali ngokucacileyo.
