Kamora hore benzene/hydrobenzene e theohele ho li-yuan tse 6000, ka lebaka la pholisi ea naha, maikutlo a 'maraka a ile a fetoha hanyane, barekisi ba bang le theko ea theko e tlase, boleng bo holimo ba benzene/hydrobenzene bo ile ba phahamisa ho phahama ha theko. La 16 Phuptjane, theko ea benzene ea oli ea Shandong e ne e ka ba 6220 yuan/ton, keketseho ea 80-140 yuan/ton. Re thehile motheo bakeng sa rebound ea hydrobenzene bekeng ena.

Hajoale, 'maraka o shebane le ho eketseha ha sekhahla sa tšebeliso ea matla a styrene, ho theoha ha sekhahla sa ts'ebetso ea phenol le keketseho ea thepa e tsoang kantle ho naha e hloekileng ea benzene.

1, ts'ebeliso e kholo ea matla a styrene e lebelletsoeng ho eketseha

Karolo ea pele ea setsi sa styrene se emisitsoeng se rera ho qala bocha, hammoho le Zhejiang Petrochemical lithane tse 600,000 tsa lisebelisoa li behiloe ka hora ea 15 ka la 16 Phuptjane, ho tsoa tlhahiso ea China le data ea tšebeliso ea matla e lebelletsoe ho ntlafatsa kakaretso. Tšebeliso ea matla a styrene e tla eketsa tlhokahalo ea benzene e hloekileng, e tla eketsa ts'ebeliso ea benzene e hloekileng, empa ka mor'a ho eketseha ha sekhahla sa ts'ebetso ea styrene, ho ntse ho hlokahala hore u ele hloko ho bapisoa ha styrene, haeba ho le thata ho theola noka ea styrene. fihlela ntlafatso ea synchronous, styrene e tobane le boemo ba phepelo le phokotso ea tlhokahalo, ka mor'a moo, styrene e tla kena butle-butle mocheso o phahameng oa off-sehla.

2, sekhahla sa ts'ebetso sa phenol ketone se ntse se fokotseha

Haufinyane tjena likhoebo tsa phenol ketone tse tlase li qalile maemong a 69%, khoeli le khoeli -1%. Har'a bona, nakong ea ho koala le ho boloka nako ea Jiangsu Ruiheng, Shanghai Sisar le Gaoqiao Petrochemical phenol ketone units, Shenghong refining phenol ketone units e ne e e-na le ts'ebetso e mpe, kahoo tekanyo ea ts'ebetso ea phenol ketone e ile ea tsoela pele ho fokotseha, ho fokotsa tšebeliso ea benzene e hloekileng, le ho theha. maikutlo a fosahetseng ka benzene/hydrobenzene e hloekileng.

3, theko ea benzene e hloekileng ea China e lebelletsoe ho eketseha

Qetellong ea nako ea tlhokomelo ea mose ho maoatle, 'me boleng ba boleng ba octane bo se bo theohile, benzene e hloekileng ea Asia e hloka ho kena Chaena bakeng sa tšilo ea lijo,' me ho lebelletsoe hore thepa e tsoang kantle ho naha e tsoang kantle ho naha e tla eketseha, e leng se tla lebisa ho phahama ha benzene ea lapeng. phepelo, ho latela pono ea khoeli le khoeli ea ho reka kantle ho naha kapa ho tloha ho lithane tse 200,000 ho isa ho tse 300,000 tsa sekala.

Ntle le moo, Hainan Refining le Chemical lithane tse ncha tse limilione tse 2.6 tsa phepelo e nchafatsang, CNOOC Huizhou e ncha ea lithane tse limilione tse 1.3 tsa ntlafatso ea tlhahiso ea aromatics le disproportionation e lebelletsoe ho kenngoa lijong hamorao, phepelo ea lapeng ea benzene e hloekileng e ile ea eketseha.

Ka nako e khuts'oane, ho kenyelletsa ho tlatsa hape ho se nang letho qetellong ea khoeli, ho lebelletsoe hore moea oa ho reka oa benzene/hydrobenzene o ka ntlafatsoa, ​​'me theko ea hydrobenzene e ka tsitsisa le ho khutla, empa bophahamo le matla e fokolang, hobane 'maraka o ntse o le holim'a litaba tse mpe,' me mohala o bohareng le o molelele o tšoaroa ka maikutlo a se nang letho.
