Ngo-2023, inkambiso iyonke yemakethe ye-toluene yaseChina iqinile, futhi ukusebenza kwemakethe ye-toluene kuyancomeka ngenxa yokusebenza okuzinzile okuyisisekelo.

Ngekota yokuqala, ukugxilwa kwezingxoxo zemakethe ye-toluene kwakhuphuka kwakhuphuka, futhi ukusekelwa okuhle okuyinhloko kwakuwukusetshenziswa okuzinzile kwemboni kaphethiloli. Ikakhulukazi, ngoJanuwari, ikusasa likawoyela ongahluziwe wamazwe ngamazwe liyenyuka, inqubomgomo yobhubhane yayixegekile, futhi uhlangothi lokunikezela lwavulwa ngenxa yedivayisi ye-Daxie disproportionation, kanye nevolumu yokuthengisa yangaphandle ye-toluene eMpumalanga China yehla ngamathani angu-30,000, futhi imboni bekulindeleke ukuthi imakethe yesikhathi esizayo ibe yinhle, isekela imakethe ye-toluene ukuthi ibe yinhle. Ngemva kokubuyela edolobheni ngemva kweholide Spring Festival ngo-February, naphezu kokuqoqwa kwechweba, imboni kaphethiloli ngenkuthalo wathenga Shandong esifundeni kwaholela izwe, futhi East China esifundeni walandela Shandong; Ngaphezu kwalokho, ezinye izimboni ezingaphansi komfula bezilokhu zigcina futhi ziqala umsebenzi, futhi ichweba seliqalile ukuya esiteji sokugcina, okwenza i-toluene izinzile ezingeni eliphezulu. NgoMashi, ngenxa yokuthengiswa kwempahla ye-toluene yi-Qingdao Lidong Foreign Trade Co., LTD., ukunikezwa kwemakethe bekulindeleke ukuthi kuqine. Futhi ukuqothuka kwamabhange aseYurophu naseMelika kunomthelela omkhulu emqondweni wabasebenzi, okwenza ukuguquguquka kwemakethe ye-toluene kube bushelelezi.

Imakethe ye-toluene yehle ngemva kokukhuphuka ngekota yesibili, futhi ukusekelwa okuhle kohlangothi lokuhlinzeka kuseku-inthanethi, kodwa isidingo esibuthakathaka siyicindezele kakhulu intengo. Ngo-Ephreli, imboni kaphethiloli yathenga ngenkuthalo, futhi ukunyuka kwentengo esifundeni saseShandong kwaholela ekwenyukeni kwentengo ezindaweni ezizungezile. Ngaso leso sikhathi, kwavuleka iwindi le-Asian-American Arbitrage, futhi ukuthunyelwa kwemikhiqizo ye-aromatics yaseNingizimu Korea e-United States kwaheha ukunaka kwemakethe. Kusukela ngoMeyi kuya kuJuni, amabhizinisi asekhaya e-toluene angena enkathini yokulungiswa kwendawo eyodwa, futhi ukunikezwa kwehle kakhulu; Kodwa-ke, izimboni zamakhemikhali kanye nekaphethiloli ezansi nomfula ngokuvamile ziyasebenza, futhi okulindelwe yi-arbitrage yase-Asia neMelika kuphoxekile, ngakho ukunikezwa akunakulungiswa okwesikhashana. Ngasikhathi sinye, ukugcwala okubanzi kukawoyela ongahluziwe kanye nezindaba zentela yokusetshenziswa ekhokhiswa emikhiqizweni ehlobene nephunga elimnandi kugubuzele imakethe, okwenza imakethe ye-toluene iqaphe.

Ukungena kwikota yesithathu yezinto ezinhle ezigxiliwe, amanani emakethe ye-toluene onyakeni aphezulu aqhubekile nokuqabuleka. Okokuqala, ezinye imikhiqizo elimnandi intela ukusetshenziswa intela amabhuzu kokwehla, superimposed embonini kaphethiloli isidingo umthengi rise; Okwesibili, iwindi lokuthekelisa likaphethiloli ne-toluene liyavulwa, futhi isidingo siyakhula. Futhi, intengo kawoyela ongahluziwe yamazwe ngamazwe ikhuphuke yafika enanini eliphakeme kakhulu kusukela ngomhlaka-12 Novemba 2022, inikeze umoya wokusekelwa kwempahla, futhi phansi kwemakethe ye-toluene kusekelwa kahle.

Ngekota yesine, iShandong Lianyi kanye ne-Daqing Longjiang Chemical disproportionation units yaqala ukusebenza, futhi i-toluene yasetshenziswa njengempahla eluhlaza ukuze kukhiqizwe i-benzene emsulwa, okubangele ushintsho olukhulu esimweni sokuhlinzekwa kwesifunda kanye nesidingo se-toluene, kanye nomehluko wentengo phakathi i-toluene ne-benzene emsulwa kube nomthelela omkhulu ekusungulweni kwamabhizinisi.

Kafushane, imakethe ye-toluene ngo-2023 ikhombisa ukuthambekela okukhuphukayo kwe-oscillation ngaphansi kokulukwa kwezinto ezintathu ezibalulekile zokuhlinzeka, isidingo kanye nokwakhiwa kwezindleko; Izici ezingezinhle azibonakali kahle.
