Ukususela ngo-2023, ixabiso lentengiso leSyrene lisebenza ngaphantsi komndilili weminyaka eli-10. Ukususela ngoko, kuya kuphambuka ngakumbi kumndilili weminyaka eli-10. Esona sizathu kukuba uxinzelelo lwe-benzene emsulwa ukusuka ekuboneleleni ngendleko zokukhulisa iindleko ukwandisa i-Styrene. Lilonke, ixabiso lestyyne lingaqhubeka lixhomekeke kukhokelo lweendleko, kwaye ibhloko yokubonelela kunye nemfuno yothungelwano lweendleko kunokuba nzima ukuphucula.
Ukususela ngo-2023, amaxabiso e-styrene ayesebenza engapheliyo kwi-10 yomgangatho ophakathi. Kwelinye icala, ukukhutshwa okukhawulezayo kwemveliso entsha ye-stanene kukhokelele ekwenzeni ukonakala kokunikezelwa kwalo kunye nobudlelwane bemfuno; Kwelinye icala, ekubeni ioyile yeZhongyuan yangena kwijelo lasezantsi ngo-2022, ithe yazinza kwaye yaxabana, ingenamda phezulu. Ngeli xesha, i-Debream Bedzene ixhomekeke ekunikezelweni okuhle kunye nobudlelwane bemfuno ukuxhasa ixabiso lesyrene. Nangona kunjalo, ngoMeyi, njengokunikezelwa kunye nobudlelwane bemfuno ye-Bezene ecocekileyo ngokuthe ngcembe, amaxabiso e-styrene

bajongana noxinzelelo lwasezantsi.
 
Ixabiso: Kunzima kwi-oyile ecekeceke ukubonisa imeko ye-UNIlnd, kodwa ukubonelelwa kunye nemfuno ye-Benzene enyulu inokwenza buthathaka okanye iqhubeke nokuxinezeleka.
Njengemveliso yamandla, ioyile ebomvu iya kuqhubeka iguquka kwimarike kwiinyanga ezintathu ezizayo ngenxa yexabiso lenzala ye-macro kunye nokuncitshiswa kwemveliso. Akuyi kubakho ngxabano iphambili, kwaye ixabiso leoyile liya kuqhubeka nokuguquguquka ngaphakathi kuluhlu. Ioyile yase-US egxile kwi- $ 65- $ 85 kwi-barrel nganye. Okwangoku, zintathu iimeko eziphambili eziye zalawula umkhondo wamaxabiso eoyile, ebizwa ngokuba yi-Federal Relorence Galomation, i-OPC + yohlengahlengiso lwemveliso, kunye notshintsho olusecaleni kwehlabathi jikelele kunye noqoqosho lwaseTshayina. Kuyimfuneko ukunikela ingqalelo kwimpembelelo yotshintsho olungalindelekanga kumaxabiso e-oyile kwezi meko ziphambili ziphambili.
Ukusukela ngo-Matshi walo nyaka, i-Benzene emsulwa ixhomekeke kakhulu ekuboneleleni kunye nemfuno (ngemfuno elungileyo yokudityaniswa kweoyile e-Asia, iqhuba i-Ania, iqhubela phambili i-Bezene i-Bezene kwimakethi yangaphandle; ukubonelelwa kwekhaya kuyageza Izinzile, kodwa ngokukhutshwa okukhawulezayo kwemveliso esezantsi edolophini, ibango liye landa). Ngexesha lenkqubo yokunyuka kwexabiso leoyile kunye nokusasazeka kwexabiso eliphantsi, bekukho i-tyrenga eqinileyo etyhutyhayo, ngelixa ngexesha lenkqubo ye-oyile incipha kunye nokusasazeka kwexabiso eliphantsi. Ukusuka kumahluko amaxabiso phakathi kwe-Benzene enyulu kunye nesyrene kumzobo 3, kunokubonwa ukuba ku-Epreli, i-Benzene emsulwa ixhomekeke kakhulu ku-styrene iqhubekile, inciphile ukuya kuthi ga kwi-1080 yuan / ton ukuphela kuka-Epreli.
Nangona kunjalo, ngoMeyi, ifuthe le-Benzene elicocekileyo kwi-styrene lenze buthathaka kakhulu, ikakhulu ngenxa yokwanda kancinci kwenani lokugcina izinto, kunye nokongezwa korhwebo lwasekhohlo kwitanki yaseMpuma China Ifama, ekulindeleke ukuba yandise uluhlu lweempahla. Okwangoku, imfuno yokudityaniswa kweoyile eYurophu naseMelika azange inyuke, elungele ukukhutshwa kwayo. Nangona kunjalo, ngembuyekezo yolungiso olukhulu kwizityalo ezimsulwa ze-Anian Homeze, ubonelelo lunyukele emva kwelinye, kwaye amaxabiso angaphandle aphantsi koxinzelelo oluthile.
Ubonelelo kunye nolwalamano lweemfuno: Ubunzima bokuhanjiswa kweendleko kunye nokuthintela amandla
Ngelixa kukho izinto eziguquguqukayo kubonelelo kunye ne-carict icala, isiphumo seendleko kumaxabiso e-styrene sitshintshelwe ukubonelela ngoxinzelelo, kodwa ubudlelwane kunye nolwalamano lwemfuno kunokuba nzima ukutshintsha kakhulu.
Okokuqala, ngokubhekisele kubonelelo, ukuqala ukusuka ephakathi, inani lezixhobo zolondolozo lweStyrene inyukile, zizonke iinkampani eziqala ukulungisa malunga ne-3.2 yezigidi zeetoni zemveliso yezixhobo. NgoJuni, ukuveliswa kwesyrene kulindeleke ukuba kunciphe iitoni eziyi-1100 ukuya kwi-1.24 yeetoni ezizigidi ezithelekiswa nazo, ukwehla kwe-8.15% xa kuthelekiswa nenyanga ephelileyo.

Okwesibini, ngokubhekisele kwimfuno, uninzi lwemveliso ye-styrene ngoJuni ikwixesha lexesha elifanelekileyo, kwaye ibango leSyrene lingancipha. Ngokwedatha ukusuka kwi-2021 ukuya kwi-2022, ibango le-styrene kwimimandla esisixhenxe emisibini yehlayo inciphile, ngokuncitshiswa kwe-11% ngo-2022, kwaye kukho ukuziqhelanisa phakathi ukubonelelwa kunye nokufuna amacala.

Ngokubanzi, ukuhanjiswa kunye nemfuno yestyrene yehlile ngoJuni, kodwa ngokuhlengahlengiswa kokuhambisa kunye ne-cariveres, kunokuba nzima ukuhambisa kunye nokwenza ukuba kube nzima ukuqhuba amaxabiso e-styrene . Ixabiso leSyrene lingaqhubeka lixhomekeke kwizikhokelo zexabiso lezindleko.
