Isimo Semakethe
Iphethini Yokuphakelwa Nesidingo
Imakethe ye-aniline yomhlaba wonke isesigabeni sokukhula okuqhubekayo. Kulinganiselwa ukuthi usayizi wemakethe ye-aniline yomhlaba wonke uzofinyelela cishe ku-8.5 billion zamaRandi aseMelika ngo-2025, kanti izinga lokukhula lonyaka elihlanganisiwe (CAGR) lihlala cishe ku-4.2%. Amandla okukhiqiza i-aniline yaseShayina adlule amathani ayizigidi ezingu-1.2 ngonyaka, alinganiselwa cishe ku-40% wamandla okukhiqiza emhlabeni wonke, futhi azoqhubeka nokugcina izinga lokukhula lonyaka elingaphezu kuka-5% eminyakeni emithathu ezayo. Phakathi kwezidingo ezingezansi ze-aniline, imboni ye-MDI (Methylene Diphenyl Diisocyanate) ifinyelela ku-70%-80%. Ngo-2024, amandla okukhiqiza i-MDI yasekhaya yaseShayina afinyelele amathani ayizigidi ezingu-4.8, futhi isidingo kulindeleke ukuthi sikhule ngesilinganiso sonyaka esingu-6%-8% eminyakeni emihlanu ezayo, okuqhuba ngqo ukwanda kwesidingo se-aniline.
Intengo Ehambayo
Kusukela ngo-2023 kuya ku-2024, intengo ye-aniline yomhlaba wonke yehla ngesivinini phakathi kwamadola aseMelika ayi-1,800-2,300 ngethani. Kulindeleke ukuthi intengo izozinza ngo-2025, ihlale cishe amadola aseMelika ayi-2,000 ngethani. Ngokuphathelene nemakethe yasekhaya, ngo-Okthoba 10, 2025, intengo ye-aniline eMpumalanga China yayingu-8,030 yuan ngethani, kanti eSifundazweni saseShandong, yayingu-7,850 yuan ngethani, zombili zikhuphuka ngama-yuan ayi-100 ngethani uma kuqhathaniswa nosuku lwangaphambilini. Kulinganiselwa ukuthi intengo yonyaka ejwayelekile ye-aniline izoshintshashintsha cishe ngama-yuan ayi-8,000-10,500 ngethani, kanye nokwehla konyaka nonyaka okungaba ngu-3%.
Isimo Sokungenisa Nokuthumela Ngaphandle
Izinqubo Zokukhiqiza Okuhlanzekile
Amabhizinisi ahamba phambili embonini, njenge-BASF, i-Wanhua Chemical, kanye ne-Yangnong Chemical, akhuthaze ukuvela kwezinqubo zokukhiqiza i-aniline eziqondisweni ezihlanzekile nezingenakhabhoni eningi ngokuthuthukisa ubuchwepheshe kanye nokuhlelwa kweketanga lezimboni okuhlanganisiwe. Isibonelo, ukwamukelwa kwendlela ye-nitrobenzene hydrogenation ukuze kuthathe indawo yendlela yendabuko yokunciphisa i-iron powder kuye kwanciphisa ngempumelelo ukukhishwa “kwemfucuza emithathu” (igesi engcolile, amanzi angcolile, kanye nemfucuza eqinile).
Ukushintshana Kwezinto Ezingavuthiwe
Amanye amabhizinisi ahamba phambili aseqalile ukukhuthaza ukusetshenziswa kwezinto zokusetshenziswa kwe-biomass ukuze kuthathelwe indawo ingxenye yezinto zokusetshenziswa zasendulo. Lokhu akusizi nje kuphela ukuthuthukisa ikhwalithi yomkhiqizo kodwa futhi kunciphisa ngempumelelo izindleko zokukhiqiza.
