一.Halofo ea bobeli ea ponelopele ea motheo

1.1 Polelo ea Tlhahiso

Ho ea ka lipatlisiso tsa Longzhong Information, indasteri ea lihlahisoa tsa aniline e rera ho haha ​​​​lithane tse 385,000 tsa matla a tlhahiso karolong ea bobeli ea 2023, 'me ha ho na moralo oa bokhoni ba ho tlohela. Bokhoni bo bocha ba tlhahiso bo ajoa haholo-holo Chaena Boroa, 'me khoebo e reriloeng e na le lisebelisoa tsa lihlahisoa tse tlase, nts'etsopele ea ketane ea indasteri, le phokotso ea theko le lipalangoang le litšenyehelo tse ling tsa ts'ebetso.

Kamora ho lokolloa ha matla a macha a tlhahiso ea aniline nakong e tlang, e tla fetola haholo mokhoa oa phepelo ea liphoofolo tse ruuoang lapeng, mme tlhahiso ea aniline naheng ea China Boroa e tla khanyetsa lifektheri tse haufi le noka e haufi, e fokotse ka katleho litšenyehelo tsa theko ea thepa e tala. . Karolong ea bobeli ea selemo, Yantai Wanhua o rerile ho ntlafatsa, 'me lisebelisoa tsohle tsa eona tsa aniline-MDI li ile tsa emisa, kapa tsa ama phepelo ea aniline ho ba bang ba bareki ba eona ba nako e telele. Ho phaella moo, Fujian Wanhua e rera ho kenya tlhahiso ka September, e nang le tšusumetso e kholo ho theko ea aniline ka boroa, 'me ho lebeletsoe hore theko ea aniline karolong ea bobeli ea selemo e ka ba 9000-12000 yuan / ton

1.2 Polelo ea Tšebeliso

Ka halofo ea bobeli ea selemo, lapeng polymerization MDI disebediswa tlhokomelo ba concentrated ka August, November le December, sesebediswa ka kakaretso lebeletsoe ho fokotseha haholo, ho phaella ho disebediswa mose ho maoatle ka July le August ho na le lihlopha tse ngata tsa tlhokomelo ea lisebelisoa, ka kakaretso. phepelo konteraka, theko ea lehae ka kakaretso ka 'na ba le matlafatsoa nyenyane, empa ka August le September ka lebaka la ho fihla ha lehlabula, mocheso o phahameng meteo ka' na ama downstream ka kakaretso mojaro, ho fokotsa matla, tlhahiso e fokolang. Hape le indasteri ea lisebelisoa tsa lapeng nakong ea off-sehla, theko e thata ho tšehetsa. Ka Mphalane le Pulungoana, ka liindasteri tse tlase tsa thepa ea ntlo le liphaephe tse kenang nakong ea tlhōrō e tloaelehileng, 'me ho lebeletsoe tlhokomelo e utloahalang ea lisebelisoa tse ling, ho ka khoneha ho tsoela pele ho phahama. Karolong ea bobeli ea selemo, sepheo se seholo ke ho fokotseha ha phepelo le ho lateloa ha lehlakore la tlhokahalo. Ha ho nahanoa hore theko ea MDI ea polymerized halofo ea pele ea selemo e bolokiloe ho 14300-16300 yuan / ton, tlhokahalo e lebeletsoe ho hlaphoheloa ka selemo, theko e tloaelehileng karolong ea bobeli ea selemo e phahame hanyenyane ho feta boemo. halofo ea pele ea selemo, 'me theko e lebelletsoeng e bolokiloe ho 15500-17000 yuan / ton.

1.3 Ponelopele ea kantle ho naha / letlooa la kantle ho naha

Hajoale, phepelo ea lapeng le tlhoko ea aniline li batla li leka-lekane, 'me cheseho ea ho romela kantle ho naha e ntse e fokola. Ho sa tsotellehe ho fokotseha ha litšenyehelo tsa tlhahiso ea li-aniline tsa malapeng, tlhokahalo e tlaase e batla e le matla, e nang le tšehetso e itseng bakeng sa theko e phahameng ea aniline. Ho lebeletsoe hore palo ea lihlahisoa tsa aniline karolong ea bobeli ea selemo e ke ke ea fetoha haholo ha e bapisoa le halofo ea pele ea selemo, empa ha ho qheleloe ka thōko hore aniline e setseng e tla rekisoa mose ho maoatle ka mor'a hore Fujian Wanhua e kene ts'ebetsong. .

二.Litšenyehelo tsa halofo ea bobeli ea bolepi

Halofong ea bobeli ea selemo, theko ea bolepi ba benzene e hloekileng ke 6280-6800 yuan/ton, e bontšang mokhoa oa ho nyoloha pele le ho theoha.

Mabapi le oli e tala, litheko tsa oli halofong ea bobeli ea selemo li hlahisitse monyetla oa ho khutla, ho bonts'a mokhoa oa ho nyoloha pele ebe o theoha hape ka kakaretso, 'me theko e tloaelehileng ea khoeli le khoeli e ka fetoha ho tloha 75-78 US. lidolara/barrel, e nang le mefuta e fokolang ea ho feto-fetoha ha maemo.

Mabapi le phepelo, boholo ba katoloso ea benzene e hloekileng ka 2023 e phethiloe halofong ea pele ea selemo, ka kakaretso ea lithane tse fetang limilione tse 3 tsa likarolo tse ncha tsa petroleum benzene le hydrobenzene li kentsoe tšebetsong, le benzene e hloekileng. tlhahiso karolong ea bobeli ea selemo e lebelletsoe ho bonts'a keketseho e kholo ha e bapisoa le halofo ea pele ea selemo. Karolong ea bobeli ea selemo, ke lithane tse 100,000 feela tsa matla a Anqing Petrochemical a ileng a atolosoa ka July, 'me lithane tse 200,000 tsa Longjiang Chemical li ne li sa tsoa hahoa qetellong ea selemo. Leha ho le joalo, Hydrojeds Bendrone o ntse a na le LOYANG ZHONGHUI 500,000 Tons, Chongland Huafeng tons - Lisebelisoa tsa Ningn JUNEH kotara.

Mabapi le tlhokahalo, tlhahiso e tlaase ea benzene e hloekileng karolong ea bobeli ea selemo e ne e tsepamisitsoe, ho kenyelletsa le sete ea bone ea styrene ea Zhejiang Petrochemical, styrene ea Anqing Petrochemical, Hengli new phenol le adipic acid, Fujian Wanhua aniline, Lusi, Shenyuan. , Baling Petrochemical caprolactam e ncha le lisebelisoa tse ling tse reretsoeng ho kenngoa ts'ebetsong, le Qingdao Bay, Huizhou Zhongxin Phenol, e ileng ea chechisoa halofo ea pele ea selemo. Ntle le mokhoa o tloaelehileng oa ho theola noka, tlhoko ea octane ho tsoa ho ethylbenzene le cyclohexane e lebelletsoe ho fana ka matlafatso ea tšebeliso ea benzene e hloekileng. Leha ho le joalo, halofong ea pele ea selemo, mefuta e meng ea mefuta e tlase e ile ea tobana le ho fokotseha ha boima ba indasteri ka mor'a ho atolosoa ha matla, 'me tšebeliso ea benzene e hloekileng e ne e le tlase ho feta matla a tlhahiso. Boemong ba tšebeliso ea ho qetela halofo ea bobeli ea selemo e ntse e se na tšepo, ho lebelletsoe hore tšebeliso ea benzene e hloekileng e tla ntlafatsoa haholo ho ea tlase ho feta boleng ba theory.

Mabapi le thepa e tsoang kantle ho naha, tlhokeho ea ho qetela United States le Europe e ntse e tsoela pele ho tepella maikutlong, 'me tlhoro ea maeto a lehlabula United States halofong ea bobeli ea selemo e tla fela ka Loetse, boikemisetso ba Asia Leboea-bochabela ho romella benzene e hloekileng Chaena. ho lebeletsoe hore e eketsehe karolong ea bobeli ea selemo, 'me molumo oa ho kenya chelete o ka khutlela boemong ba lithane tse 250-300,000 / khoeli.

Ka kakaretso, theko ea oli e tala karolong ea bobeli ea selemo e batla e tsitsitse, 'me tšehetso ea litšenyehelo e kopantsoe. Sesebediswa sa tlhahiso ea theory theory se feta kemiso e ncha ea petroleum benzene le hydrobenzene, empa sekhahla sa ts'ebetso se lebelletsoe ho theoha ka kakaretso, 'me molumo oa kantle o lebelletsoe ho eketseha, kahoo phepelo le tlhokahalo ea karolo ea benzene e hloekileng e ntlafalitsoe, empa mefuta e fapaneng e lekanyelitsoe. Theko ea benzene e hloekileng e lebelletsoe kotareng ea boraro ka lebaka la ho khutla ha lisebelisoa tsa tlhokomelo e tlase le kaho ea lisebelisoa tse ncha ho fumana matla a ntseng a phahama, empa ka lebaka la phaello e fokolang e sa kopanngoeng, benzene e hloekileng e ile ea phahama kaholimo ho naha. tlase, ka tokollo ya tlhahiso ya tlhahiso ya hydrobenzene kotareng ya bone, lehlakore la phepelo le tlhokeho le boetse le fetohela ho phepelo e ngata, mme theko e lebelletsoe ho bonts'a tšekamelo e tlase.

Karolong ea bobeli, aniline e ile ea angoa ke tlhokahalo e fokolang 'me ea qala ho kena mocha o theohelang. Ho ipapisitsoe le phetoho e reriloeng ea Yantai Wanhua ka Phato, haeba moralo oa ntlafatso o phethahala joalo ka ha o reriloe, o ka khona ho hula 'maraka oa aniline. Leha ho le joalo, ka September, lihlopha tsa Fujian Wanhua le Chongqing Changfeng 2 li ile tsa kenngoa ts'ebetsong, 'me phepelo ea aniline South China le Southwest China e ile ea eketseha haholo, ea matlafatsa mehloli e haufi ea thepa ea thepa. Ka kakaretso, kotara ea bobeli le kotara ea boraro ea 'maraka oa aniline e fokola, empa karolong ea bone, ba bang ba ile ba qala ho fumana litaelo bakeng sa selemo se tlang, tlhokahalo ea lihlahisoa tse tala e na le keketseho e itseng, kotara ea bone ea theko ea aniline e lebelletsoe ho khutla. bapisoa le kotara ea boraro.
