Imeko yeMarike
Iphethini yokubonelela kunye nemfuno
Imarike ye-aniline yehlabathi ikwinqanaba lokukhula okuzinzileyo. Kuqikelelwa ukuba ubungakanani bemarike ye-aniline yehlabathi buza kufikelela kwi-8.5 yeebhiliyoni zeerandi zaseMelika ngo-2025, kunye nezinga lokukhula lonyaka elihlanganisiweyo (CAGR) elihlala limalunga ne-4.2%. Umthamo wemveliso ye-aniline yaseTshayina udlule kwi-1.2 yezigidi zeetoni ngonyaka, ufikelela phantse kwi-40% yamandla emveliso iyonke yehlabathi, kwaye uya kuqhubeka nokugcina izinga lokukhula lonyaka elingaphezulu kwe-5% kwiminyaka emithathu ezayo. Phakathi kweemfuno ezisezantsi ze-aniline, imboni ye-MDI (Methylene Diphenyl Diisocyanate) ifikelela kwi-70%-80%. Ngo-2024, amandla emveliso ye-MDI yasekhaya yaseTshayina afikelele kwi-4.8 yezigidi zeetoni, kwaye kulindeleke ukuba imfuno ikhule ngesantya sonyaka se-6%-8% kwiminyaka emihlanu ezayo, nto leyo ekhokelela ngokuthe ngqo ekunyukeni kwemfuno ye-aniline.
Intsingiselo yexabiso
Ukususela ngo-2023 ukuya ku-2024, ixabiso le-aniline lehlabathi liye latshintsha ukusuka kwi-1,800 ukuya kwi-2,300 yeedola zaseMelika ngetoni nganye. Kulindeleke ukuba ixabiso lizinze ngo-2025, lihlale malunga ne-2,000 yeedola zaseMelika ngetoni nganye. Ngokwemarike yasekhaya, ngo-Okthobha 10, 2025, ixabiso le-aniline eMpuma China yayiyi-8,030 yeeyuan ngetoni nganye, kwaye kwiPhondo laseShandong, yayiyi-7,850 yeeyuan ngetoni nganye, zombini zinyuka nge-100 yeeyuan ngetoni nganye xa kuthelekiswa nosuku oludlulileyo. Kuqikelelwa ukuba ixabiso eliqhelekileyo lonyaka le-aniline liya kutshintshatshintsha malunga ne-8,000-10,500 yeeyuan ngetoni nganye, kunye nokwehla konyaka malunga ne-3%.
Imeko yokungenisa nokuthumela ngaphandle
Iinkqubo zokuvelisa ucoceko
Amashishini aphambili kushishino, afana neBASF, iWanhua Chemical, kunye neYangnong Chemical, akhuthaze uphuhliso lweenkqubo zemveliso ye-aniline ukuya kwiindlela ezicocekileyo neziphantsi kwekhabhoni ngokuphucula ubuchwepheshe kunye noyilo oludibeneyo lwetyathanga lemizi-mveliso. Umzekelo, ukwamkelwa kwendlela ye-nitrobenzene hydrogenation ukuthatha indawo yendlela yendabuko yokunciphisa umgubo wentsimbi kuye kwanciphisa ngempumelelo ukukhutshwa "kwenkunkuma ezintathu" (igesi engcolileyo, amanzi amdaka, kunye nenkunkuma eqinileyo).
Ukutshintshwa kwezinto eziluhlaza
Amanye amashishini aphambili aqalise ukukhuthaza ukusetyenziswa kwezinto eziluhlaza zebhayomass ukuze kuthathelwe indawo inxalenye yezinto eziluhlaza zefosili. Oku akuncedi nje kuphela ekuphuculeni umgangatho wemveliso kodwa kunciphisa ngempumelelo iindleko zemveliso.
