Kutora chiitiko chezviitiko zvikuru zviri kuitika mumusika wegasi rakanyungudutswa muna 2023, pane zvinhu zviviri zvinobata zvakananga izvo zvakakosha zvekupa uye kudiwa: chekutanga, tsaona yekuchengetedza yeNingxia resitorendi; Ii. Alkylate mafuta ari pasi pemutero wekushandisa. Izvi zviitiko zviviri zvikuru zvinokanganisa misika yevagari uye olefin kabhoni 4 zvichiteerana.

Tsaona dzekuchengetedza dzinokanganisa zvakananga kudiwa kwegasi revanhu, kuteedzera kwemutemo mumunda, kusateedzera hakuzadzise zvinodiwa nekurambidzwa, kune zvikwata zvenguva dzose kusiya musika; Nekudaro, zvinewo kukanganisa pakushandiswa kwegasi revanhu.

Pakave nemishumo yakawanda uye kuongororwa kwekuchinja kukuru kwemusika kunokonzerwa nemutero wekushandisa pamafuta ealkylate uye kuwedzera kwakanyanya kwemitengo. Mwedzi mishanu yapfuura kubva pakuitwa kwegwaro, uye isu ticha tarisa maitiro chaiwo pamusika wekabhoni mana kuburikidza nedata.

Kuburikidza nekuchinja kwekuda kweC4 ye olefin mumagetsi e-alkylation, zvinogona kuonekwa kuti kudiwa kunenge kwakagadzikana mukutanga kana mwedzi miviri isati yatanga mitemo yakakodzera. Zororo diki muna Chivabvu raive mwaka wepamusoro wekudiwa kwemafuta, iyo yaifanirwa kunge yakave yakakwira nhanho yekuvakwa kwemidziyo yealkylation, asi mutero wekushandisa waibvisirwa mukupera kwepakati nekunonoka, uye mamwe mabhizinesi akadzikisa mutoro kana kumisa basa. kudzivirira njodzi, zvichikonzera kudzikira kwehuwandu hwekushanda kwealkylation uye kudiwa, uye chiyero chekushandisa chealkylation simba chakadonha chinosvika gumi muzana mapoinzi munguva pfupi. Mushure mokunge inenge hafu yemwedzi yemhirizhonga, iyo alkylated mafuta uye olefin C4 misika yakawana zvakare imwe nzvimbo yekuenzanisa: mutengo weolefin C4 wakaderedzwa zvikuru.

Muna May, olefin carbon 4 yeChina mutengo wakawira 11.76%, yakaramba ichiderera 8.84% munaJune, uye yakadzoka zvakare muna August; Alkylation purofiti yaive yakakwira mugasi rekuderera, asi purofiti yakadzikira zvishoma nezvishoma nekutanga kwemutero munguva yakazotevera, uye yakadzoserwa muna Nyamavhuvhu, mushure mekurasikirwa kwenguva refu. Iyo rebound yeyakagadzirwa kabhoni 4 imhaka yekushanda kwekuchengetedza kwemutengo wakaderera alkylation zvishandiso. Kudzika uku kunosanganisira alkylation units pamwe nezvimwe. Ikabatwa nedivi rekurambidza, mutengo wekabhoni ina yeolefin wadonha panzvimbo yakaderera, kwete chete mari yechishandiso chealkylation, asiwo chikamu cheiyo olefin isomerization mudziyo, mamwe emabhizinesi akamiswa akatanga basa kana akatangazve zvirongwa zvebasa, uye rutivi rwekudiwa rwakavandudzika zvishoma nezvishoma.

Musika weolefin kabhoni 4 hauna kudzoka mukudzikama nekuda kwechiyero chitsva, uye kuongorora nguva nenguva kuchakanganisa maitiro mumatanho, uye remangwana olefin kabhoni 4 richaramba richitsvaga budiriro nyowani mumhirizhonga.
