I. Daim ntawv thov teb

1-Butene yog ib qho tseem ceeb ntawm cov khoom siv raw khoom, feem ntau yog siv hauv cov nram qab no:

1. Polymer Production (Core Application)

· Polyethylene Comonomer: Copolymerized nrog ethylene los ua High-Density Polyethylene (HDPE) thiab Linear Low-Density Polyethylene (LLDPE). Qhov no yog daim ntawv thov tseem ceeb tshaj plaws ntawm 1-butene. Hauv kev lag luam polyolefin, LLDPE yog thaj chaw siv ntau tshaj plaws, suav txog 81.5% ntawm tag nrho cov kev siv hauv 2024.

· Poly-1-butene (PB-1) Pipes: Siv rau hauv cov kav dej, cov yeeb yaj kiab, thiab lwm yam kev siv, nrog rau kev lag luam loj zuj zus ntxiv.

2. Chemical Intermediates

· Butadiene Production: Siv los tsim 1,3-butadiene, uas yog siv ntxiv hauv kev tsim cov roj hmab hluavtaws.

Sec-butanol (SBA) thiab Methyl Ethyl Ketone (MEK): Synthesized los ntawm hydration tshua.

· Lwm yam Derivatives: Yuav siv tau los tsim valeraldehyde, n-butanol, lubricant additives, methyl methacrylate (monomer rau plexiglass), thiab lwm yam.

3. Lwm yam kev siv

· Siv raws li cov qauv roj thiab npaj tshwj xeeb cov qauv roj sib tov.

· Siv hauv kev tsim cov isoprene, hluavtaws roj hmab, thiab lwm yam.

II. Kev xav tau kev hloov pauv thiab lub sijhawm

Kev ntxhov siab ntawm Cov Kev Cai Lij Choj: LLDPE tseem yog thaj chaw siv ntau tshaj plaws, tab sis nyob rau hauv qhov kev xav mus rau siab -kawg daim ntawv thov, kev hloov ntawm 1-butene los ntawm 1-hexene thiab 1-octene yog nrawm.

Emerging Growth Drivers: Kev thov rau cov tshuaj zoo xws li poly-1-butene (PB-1) kav thiab butanone (MEK) yog loj hlob ntawm tus nqi siab tshaj 8%.

High -End Transformation: Nrog rau kev txhim kho ntawm siab- cov ntaub ntawv kawg xws li Polyolefin Elastomers (POE), qhov kev thov rau siab -purity 1-butene yuav tsum loj hlob.

III. Cov Kev Sib Tw Loj

Structural Oversupply: Hauv tsev 1-butene tab tom ntsib kev tsim khoom ntau dhau, feem ntau vim yog homogenization ntawm cov qib comonomer yas.

Raw Material Nqe Hloov Pauv: Kev hloov pauv ntawm cov nqi ethylene cuam tshuam rau cov nqi tsim khoom.

Environmental Siab: Integrated refining thiab tshuaj tej yaam num yuav tsum tau nruab nrog carbon capture technologies. Nws tau kwv yees tias carbon emission siv yuav txo qis los ntawm 15% -20% los ntawm 2030 piv rau 2026.
