Intengo yemakethe yasekhaya yecyclohexanonewawela ekushintshashintsheni okuphezulu ngo-2022, ekhombisa iphethini ephezulu ngaphambi nangemuva ngemuva. Kusukela ngoDisemba 31, ukuthatha intengo yokulethwa emakethe yase-East China njengesibonelo, inani lentengo lingu-8800-8900 yuan / ton, phansi 2700 yuan / ton noma 23.38% ukusuka ku-11500-116% kusuka ku-11500-116% yuan / ton ngesikhathi esifanayo unyaka; Intengo ephansi yonyaka yayingu-8700 yuan / ithoni, inani eliphakeme lalingu-12900 yuan / ithoni, kanye nentengo ephakathi yonyaka yayingu-11022.48 yuan / ithoni, ukwehla konyaka ka-3.68%. Ngokukhethekile, imakethe ye-cyclohexanone iguqukele kakhulu engxenyeni yokuqala yonyaka. Ekota yokuqala ka-2022, intengo ye-cyclohexanone yasukuma yaphela yavele yahlala ezingeni eliphakeme. Ngenxa yokukhuphuka kwe-benzene emsulwa, ukwesekwa kwezindleko kuzinzile. Ngaphezu kwalokho, imishini ye-cyclohexanone exhasa amabhizinisi awo e-lactam ku-DownTream ayijwayelekile. Imikhiqizo ilungiselelwe ngaphambi komkhosi wentwasahlobo, futhi imicu yamakhemikhali ibuyiselwe kakhulu. Imakethe ye-cyclohexanone ephelele isehlangothini oluphezulu. Ngemuva komkhosi wentwasahlobo, ngaphansi kokuholwa uwoyela wamazwe angaphandle, impahla eluhlaza emsulwa umsulwa uBenzene waqhubeka nokuphindisela, imikhiqizo engezansi ye-benzene emsulwa yakhuphuka, futhi iketanga lezezimboni lenze kahle. Ngaphezu kwalokho, ukunikezwa kwe-cyclohexanone kwehle, imakethe ikhuphukile kakhulu, futhi kukhona ne-intraday inyuka futhi iwe. NgoMashi, imakethe yahlangana kancane kancane ukumelana, ukusukuma nokuwa kwamafutha aluhlaza. "Igolide, isiliva nelesine" elibangelwa yibhubhane "kwaphuthelwa yisidingo sendabuko. Esikhathini esifushane, ukungqubuzana okuphakathi kwe- "aket okuzinzile" ye-upstream cyclohexanone kanye ne-caploractam kanye "nesidingo esibuthakathaka" sezindwangu esibulalayo kuzoba yingqikithi enkulu. NgoMeyi, ngokulawulwa kwesimo sebhubhane kanye nokulungiswa kwesidingo se-terminal, izinga lenzuzo leketanga lezimboni selithuthukile. Ngaphansi kwezinto ezithandekayo zokukhishwa kwezigaba zokufunwa kwezidingo kanye nomthelela omkhulu we-benzene emsulwa, imakethe ye-cyclohexanone ishaye inani eliphakeme le-12750 yuan / ton ngonyaka.
Engxenyeni yesibili yonyaka, imakethe yaseCyclohexanone yaqhubeka yehla. NgoJuni Agasti, inani lentengo yezinto eziphilayo ezingcolile zihlanzekile uBenzene. Engxenyeni yokuqala yonyaka, ngenxa yokukhula okusheshayo kwamandla okukhiqizwa okusha kwe-bewstream we-benzene emsulwa kanye nokuxhaswa okuhle kowoyela wamafutha omhlaba jikelele kanye nokusungula kwe-benzeze emsulwa, inani le-benzene emsulwa ephukile ngayo yonke indlela. Kodwa-ke, engxenyeni yesibili yonyaka, ethintekile ngokuwohloka okuphezulu kwamafutha angu-crude wezwe lonke kanye nesidingo esiphansi nokuqala, ukufika kwe-benzene emsulwa e-East China kwanda. Imakethe ye-benzene emsulwa ayisakhuphuki, futhi intengo yehla ngokushesha. Ngasikhathi sinye, isidingo esiphansi se-cyclohexanone sibuthakathaka. Ngenxa yokuthola okwenele, imakethe ye-cyclohexanone ibilokhu iwa yonke indlela, okunzima ukukhuphula. Ngokwehla kwamanani, inzuzo yenhlangano iyaqhubeka yehla. U-Yangmei FengXi, uShandong Halidi, uJiangsu Halidi, Uphiko lwe-Lunixidation Unit, JINING BANK OF China namanye amayunithi wevolumu yezimpahla ayeke ukukhiqizwa noma ukuncishiswa okuncishisiwe. Umthwalo osebenzayo ophelele wevolumu yezimpahla wawungaphansi kwama-50%, futhi ukuhlinzekwa kancane kwehla kancane. Ngokuya ngesidingo, i-caploractam isemandleni anele, lo mkhiqizo ulahlekelwe yisikhathi eside, futhi umthwalo ophelele osebenzayo uphansi cishe ngama-65%. I-Interner Mongolia Qinghua, Heze Xuyang, Hubei Sanning, Zhejiang Juhua caploractam yokupaka, i-zhejing jujua capechemical, nopende we-balling, upende ophansi, upende, okhalweni lwemithi, phakathi nezinye izimakethe ze-solvent nazo isikhathi sesizini. Isidingo se-towstream amakhemikhali amakhemikhali futhi solvent ampofu. Amathuluzi athile kuphela ama-oxidation oxidation abiza ngaphezulu, futhi inani elincane le-cyclohexanone kusenzima ukukhulisa intengo yemakethe ye-cyclohexanone. Ekupheleni kuka-Agasti, intengo e-East China yawa kwa-9650 yuan / ton.
NgoSepthemba, imakethe ye-cyclohexanone yazinza kancane kancane yathuthuka futhi yavuka, ikakhulukazi ngenxa yokunyuka kwemakethe yezinto ezibonakalayo ezihlanzekile ze-benzene. Izindleko zisekelwa kahle. I-Downstream Amide inyuse ikhuphuka ngokuqinile, futhi amakhemikhali amakhemikhali adinga ukulandela. Intengo ephansi ye-cyclohexanone yawa nokugxila kokuthengiselana, okuqhutshwa yisimo esihle. Ngaphezu kwalokho, isidingo sokugcwaliswa kabusha ngaphambi kosuku lukazwelonke lwasekelwa ukukhuphuka kokugxila kwemakethe. Ngemuva kweholide losuku lukazwelonke, lwaqhubeka nokuvuka. Ngenxa yokukhuphuka okujwayelekile ezimakethe zaphesheya kwezilwandle, amanani entengo kawoyela ongahluziwe kanye ne-benzene emsulwa emsulwa. Isekelwa yizindleko, intengo ye-cyclohexanone kancane kancane yavuka kuye ngo-10850 yuan / ton. Kodwa-ke, njengoba kancane kancane kancane kancane, amanani entengo endla, abhujiwe ezifuywayo kanye nasendaweni yasekhaya kanye nemakethe yehle, futhi imakethe yawela emuva.
Kulinganiselwa ukuthi ngo-2023, ngokwenziwa kahle kwenqubomgomo ye-Earinity yasekhaya kanye nokulindelwe okuhle kwe-Macro-Economy, ukufunwa kwemakethe kwe-cyclohexanone kulindeleke ukuthi kuvuke. Kodwa-ke, eminyakeni emibili yakamuva, kube namakhono amaningi okukhiqiza amasha, kanti inani elikhulu lemishini emisha lizofakwa ekukhiqizweni ngokuzayo, futhi amaphrojekthi amaningi asekela ukukhiqizwa. Umkhuba we-cyclohexanone caplactam we-slip ukuhlanganiswa kwe-slip kuyabonakala ngokwengeziwe. Mayelana nezindleko, ngaphandle kwenzuzo eqinile ukukhuthaza noma ukulondolozela ukuthambekela okuguqukayo kumafutha angaphandle kwe-crude, i-benzene emsulwa kusenzima ukuphindaphinda, futhi izindleko ze-cyclohexanone zivame ukusekelwa; Ngaphezu kwalokho, ingcindezi eyeqile yomkhakha we-Downstream Atide izovela kancane kancane, futhi ingcindezi yokuncintisana yentengo yemakethe ye-cyclohexanone izoqhubeka nokwanda, futhi izokhawulelwa ukulahleka kwesikhathi eside komkhakha.
