Xa sijonga iziganeko eziphambili ezenzeka kwimarike yegesi enyibilikisiweyo ngo-2023, kukho izinto ezimbini ezichaphazela ngokuthe ngqo iziseko zobonelelo kunye nemfuno: okokuqala, ingozi yokhuseleko kwindawo yokutyela yaseNingxia; Ii. Ioyile ye-alkylate ihlawuliswa irhafu yokusebenzisa. Ezi ziganeko zimbini ziphambili zichaphazela iimarike ze-civil kunye ne-olefin carbon 4 ngokwahlukeneyo.

Iingozi zokhuseleko zichaphazela ngqo imfuno yegesi yoluntu, ukuthotyelwa komthetho kuya ebaleni, ukungathotyelwa komthetho akuhlangabezani neemfuno zokuvalwa, ukuya kwiiyunithi eziqhelekileyo ukuze ziyeke ukumaketha; Nangona kunjalo, ikwanefuthe elibi ekusetyenzisweni kwegesi yesiphelo sabantu.

Kukho iingxelo ezininzi kunye nohlalutyo lotshintsho olukhulu kwimarike olubangelwe yirhafu yokusebenzisa kwi-alkylate oil kunye nokunyuka okukhulu kweendleko. Sele kudlule iinyanga ezintlanu ukusukela ekuphunyezweni kwalo mgaqo-nkqubo, kwaye siza kujonga impembelelo ethile kwimarike ye-carbon four ngedatha.

Ngotshintsho kwimfuno ye-C4 ye-olefin kwizixhobo ze-alkylation, kunokubonwa ukuba imfuno izinzile kwinyanga yokuqala okanye ezimbini ngaphambi kokungeniswa kwemigaqo-nkqubo efanelekileyo. Iholide encinci ngoMeyi yayilixesha eliphambili lemfuno yeoyile, ebelifanele ukuba liphezulu kakhulu ekwakhiweni kwezixhobo ze-alkylation, kodwa irhafu yokusetyenziswa yayihlawuliswa ekupheleni kwexesha eliphakathi nelisekupheleni, kwaye amanye amashishini anciphisa umthwalo okanye amisa umsebenzi ukuze aphephe iingozi, nto leyo eyabangela ukwehla kwezinga lokusebenza kwe-alkylation kunye nemfuno, kwaye izinga lokusetyenziswa kwamandla e-alkylation lehla phantse ngama-10 eepesenti kwixesha elifutshane. Emva kwesiqingatha senyanga sokuphazamiseka, imakethi yeoyile ye-alkylated kunye ne-olefin C4 yaphinda yafumana inqanaba elitsha lokulinganisela: ixabiso le-olefin C4 liye lehla kakhulu.

NgoMeyi, ixabiso le-olefin carbon 4 laseTshayina lehle nge-11.76%, laqhubeka nokwehla nge-8.84% ngoJuni, laza laphinda labuya ngo-Agasti; Inzuzo ye-alkylation yayiphezulu kwinqanaba lokuhla kwegesi yezinto eziluhlaza, kodwa inzuzo yehla kancinci kancinci xa kuqala irhafu kwixesha elizayo, yaza yaguqulwa ngo-Agasti, emva kokulahleka kwexesha elide. Ukubuyela kwakhona kwe-carbon 4 yezinto eziluhlaza kungenxa yokugcinwa okusebenzayo kwezixhobo ze-alkylation ezixabiso liphantsi. Oku kuquka iiyunithi ze-alkylation kunye nezinye. Ichatshazelwe licala lomgaqo-nkqubo othintelayo, ixabiso le-carbon four ye-olefin liye lehla laya kwindawo ephantsi, kungekuphela nje ingeniso yesixhobo se-alkylation, kodwa kunye nesabelo sesixhobo se-olefin isomerization, amanye amashishini amisiweyo aqalise kwakhona umsebenzi okanye aqalise kwakhona izicwangciso zomsebenzi, kwaye icala lemfuno liye laphucuka kancinci kancinci.

Imakethi ye-olefin carbon 4 ayikabuyi kwimeko entle ngenxa yokulinganisela okutsha, kwaye ukuhlolwa ngamanye amaxesha kuya kuchaphazela umkhwa ngokwamanqanaba, kwaye i-olefin carbon 4 yexesha elizayo isaza kufuna uphuhliso olutsha kwingxubakaxaka.
