Ngo-2023, umkhuba jikelele wemakethe ye-toluene yaseShayina unamandla, futhi ukusebenza kwemakethe ye-toluene kuyancomeka ngenxa yokusebenza okuyisisekelo okuzinzile.

Kwikota yokuqala, ukugxila kwengxoxo yemakethe ye-toluene kwenyuka kakhulu, futhi ukwesekwa okuyinhloko okuhle kwaba ukusetshenziswa okuzinzile kwemboni kaphethiloli. Ngokukhethekile, ngoJanuwari, ikusasa lamafutha angahluziwe emhlabeni wonke lenyuka kakhulu, inqubomgomo yobhubhane yayikhululekile, kanti uhlangothi lokunikezwa lwavulwa ngenxa yedivayisi yokungalingani kwe-Daxie, futhi umthamo wokuthengisa wangaphandle we-toluene eMpumalanga China wehliswa ngamathani angu-30,000, futhi imboni yayilindele ukuthi imakethe yesikhathi esizayo ibe yinhle, isekele imakethe ye-toluene ukuthi ibe yinhle. Ngemva kokubuyela edolobheni ngemuva kweholide le-Spring Festival ngoFebhuwari, naphezu kokuqongelela kwechweba, imboni kaphethiloli ethenge ngenkuthalo isifunda saseShandong yahola izwe, kanti isifunda sase-East China salandela iShandong; Ngaphezu kwalokho, ezinye izimboni ezingezansi bezilokhu ziqoqa futhi ziqala umsebenzi, futhi ichweba seliqalile ukuya esigabeni sokugcina, okwenza i-toluene izinze ezingeni eliphezulu. NgoMashi, ngenxa yokuthengiswa kwempahla ye-toluene yi-Qingdao Lidong Foreign Trade Co., LTD., ukunikezwa kwemakethe kwakulindeleke ukuthi kube kuncane. Futhi ukuqothuka kwamabhange aseYurophu naseMelika kunomthelela omkhulu endleleni abacabanga ngayo abaqhubi, okwenza ukuguquguquka kwemakethe ye-toluene kube lula.

Imakethe ye-toluene yehle ngemuva kokukhuphuka kwikota yesibili, kanti ukwesekwa okuhle kohlangothi lokunikezwayo kusese-inthanethi, kodwa isidingo esibuthakathaka sinciphise kakhulu intengo. Ngo-Ephreli, imboni kaphethiloli yathenga ngenkuthalo, kanti ukukhuphuka kwentengo esifundeni saseShandong kwaholela ekukhuphukeni kwentengo ezindaweni ezizungezile. Ngesikhathi esifanayo, iwindi le-arbitrage lase-Asia-American lavulwa, futhi ukuthunyelwa kwemikhiqizo ye-aromatics yaseNingizimu Korea e-United States kwaheha ukunaka kwemakethe. Kusukela ngoMeyi kuya kuJuni, amabhizinisi e-toluene asekhaya angena esizini yokulungisa ephakathi, futhi ukunikezwa kwehle kakhulu; Kodwa-ke, izimboni zamakhemikhali nophethiloli ezingezansi ngokuvamile ziyasebenza, futhi amathemba okuthumela ngaphandle kwe-arbitrage yase-Asia neyaseMelika ayadumala, ngakho ukunikezwa akusekho okwesikhashana ukugcinwa. Ngesikhathi esifanayo, ukuminyana okukhulu kukawoyela ongahluziwe kanye nezindaba zentela yokusetshenziswa ekhokhiswa emikhiqizweni ye-aromatics ehlobene kwamboza imakethe, okwenza imakethe ye-toluene iqaphele.

Njengoba kungene kwikota yesithathu yezici ezinhle ezigxile, amanani emakethe ye-toluene ngonyaka aphezulu aqhubeka nokuvuselela. Okokuqala, eminye imikhiqizo enuka kamnandi yokukhokhisa intela yokusetshenziswa iyanda, ibekwe phezu kokwenyuka kwesidingo sabathengi embonini kaphethiloli; Okwesibili, kuvulwe iwindi lokuthumela ngaphandle uphethiloli ne-toluene, futhi isidingo siyanda. Futhi, intengo yesikhathi esizayo kawoyela ongahluziwe emhlabeni wonke ikhuphukele entengo ephezulu kakhulu kusukela ngoNovemba 12, 2022, okunikeza umoya wokusekelwa kwezimpahla, futhi phansi kwemakethe ye-toluene kusekelwa kahle.

Kwikota yesine, amayunithi okungalingani kwamakhemikhali eShandong Lianyi kanye neDaqing Longjiang aqaliswa ukusebenza, futhi i-toluene yasetshenziswa njengezinto zokusetshenziswa ukukhiqiza i-benzene emsulwa, okwaholela ekushintsheni okukhulu esimweni sokuhlinzekwa kwesifunda kanye nesidingo se-toluene, futhi umehluko wentengo phakathi kwe-toluene ne-benzene emsulwa waba nomthelela omkhulu ekuqaleni kwamabhizinisi.

Ngamafuphi, imakethe ye-toluene ngo-2023 ikhombisa ukuthambekela okukhuphukayo kokuguquguquka ngaphansi kokuhlanganiswa kwezici ezintathu eziyinhloko zokuhlinzeka, ukufunwa kanye nokwakheka kwezindleko; Izici ezimbi azibonakali kahle.
