2. Txuj Ci Ntau Lawm
Isobutylene feem ntau yog muab tau los ntawm:
Chav tawg ntawm naphtha lossis ethane - ib tug los ntawm ethylene ntau lawm.
Dej Catalytic Cracking (FCC) Hauv Kev Ua Kom Zoo - Muab rho tawm los ntawm C₄ Hydrocarbon Streams.
Dehydogenation ntawm isobutane - catalytic hloov dua siab tshiab (piv txwv li, siv pt / al₂o₃).
Kev sib cais los ntawm C₄ Raffinate - los ntawm rho tawm lossis distillation (piv txwv li, mtbe decomposition).
3. Cov ntawv thov loj & kev lag luam siv
① Roj & Petrochemical Kev Lag Luam
MTBE / ETUHET NTAU LAWM - Roj Av Octane Boose (phaased tawm hauv qee thaj tsam vim kev txhawj xeeb ib puag ncig).
Alkylate roj av - reacted nrog iSobutane los tsim cov roj siab siab- octane roj.
Isooctane & Synthetic Paraffinic Kerosene (SPK) - Dav Hlau Roj Cheebtsam.
② Roj Hmab & Polymers
Butyl Roj Hmab (IIR) - Siv rau hauv log sab hauv Linner (Cov Huab Cua Zoo Tshaj).
Polyisobutylene (PIB) - Ranges los ntawm Qis MW (roj nplua nyeem (roj nplua nyeem) rau MW siab (cov nplaum).
Butyl roj hmab halogenation (CIIR / BIIR / BIIR) - txhim kho cov cua sov ua rau cov khoom siv kho mob kub.
③ Tshuaj lom neeg nruab nrab
Methyl Methacrylate (MMA) - Rau Acrylic iav (PMMA), Txheej, thiab cov nplaum.
Tert - butyl cawv (tba) - kuab tshuaj thiab precursor rau cov ntxhiab / flavors.
Antioxidants (BHT, BHA) - Khoom Noj Khoom Haus thiab Yas Stormiilizers.
Cov ntawv thov tshwj xeeb
