Ina tirohia ngā kaupapa nui i puta i te mākete hau wai i te tau 2023, e rua ngā mea e pā tika ana ki ngā kaupapa matua o te tuku me te tono: tuatahi, te aituā haumaru o te wharekai o Ningxia; II. Kei raro i te taake kai te hinu alkylate. Ka pā ēnei kaupapa nui e rua ki ngā mākete ā-iwi me te mākete olefin carbon 4.

Ka pā tika ngā aituā haumaru ki te tono mō te hau ā-iwi, ka uru ki te mara ture, ka kore e tutuki i te ture ngā whakaritenga o te aukati, ka tukuna e ngā waeine noa te mākete; Heoi, he pānga kino anō hoki ki te whakamahinga hau ā-iwi.

He maha ngā pūrongo me ngā tātaritanga kua puta mō ngā huringa nui o te mākete i puta mai i te taake kai mō te hinu alkylate me te pikinga tere o ngā utu. E rima marama kua pahure mai i te whakatinanatanga o te kaupapa here, ā, ka tirohia e tātou te pānga motuhake ki te mākete waro-whā mā roto i ngā raraunga.

Nā te panonitanga o te tono mō te C4 o te olefin i roto i ngā taputapu alkylation, ka kitea he pumau te tono i roto i te marama tuatahi, i te rua rānei i mua i te whakaurunga o ngā kaupapa here e tika ana. Ko te hararei iti i te marama o Mei te wā tino nui mō te tono hinu, he taumata teitei pea tēnei mō te hanganga o ngā taputapu alkylation, engari i tukuna te taake kai i te mutunga o te tau waenga me te mutunga, ā, i whakaitihia e ētahi umanga te taumahatanga, i mutu rānei te mahi hei karo i ngā mōrearea, ka heke te tere whakahaere me te tono alkylation, ā, tata ki te 10 ōrau te hekenga o te tere whakamahinga o te kaha alkylation i roto i te wā poto. I muri i te tata ki te hawhe marama o te raruraru, kua kitea anō e te mākete hinu alkylated me te olefin C4 tētahi taurite hou: kua tino heke te utu o te olefin C4.

I te marama o Mei, i heke te utu o te waro 4 olefin o Haina mā te 11.76%, i heke tonu mā te 8.84% i te marama o Hune, ā, i hoki anō i te marama o Ākuhata; i teitei ake ngā hua o te alkylation i te wā o te hekenga o te hau o ngā rauemi mata, engari i heke haere ngā hua i te tīmatanga o te taake i te wā o muri mai, ā, i hurihia i te marama o Ākuhata, whai muri i te mate roa. Ko te hokinga mai o te waro 4 rauemi mata nā te kaha o te penapena i ngā taputapu alkylation utu iti. Kei roto i tēnei hekenga ngā waeine alkylation me ētahi atu. Nā te taha kaupapa here here, kua heke te utu o te waro whā o te olefin ki te tūranga iti, ehara i te mea ko te moni whiwhi o te taputapu alkylation anake, engari ko te utu wehewehe o te taputapu isomerization olefin, kua tīmata anō ētahi o ngā umanga kua mutu te mahi, kua tīmata anō rānei i ngā mahere mahi, ā, kua piki haere te taha tono.

Kāore anō te mākete waro olefin 4 kia hoki ki te marino nā te taurite hou, ā, ka pāngia hoki te ia e te tirotiro i ia wā, i ia wā, ā, ka rapu tonu te waro olefin 4 ā muri ake nei i ngā whanaketanga hou i roto i te ngangau.
