Cov Catalyst Siab Tshaj Plaws Qhib Kev Ua Haujlwm Zoo hauv Alkylation thiab Bio-Roil Upgrading
Tus thawj coj tsim kho tshiab ntawm lub tshuab molecular sieve hnub no tau tshaj tawm cov ntawv thov tshiab ntawm nws cov beta zeolite catalysts, daws cov teeb meem tseem ceeb hauv kev ua cov hydrocarbon hnyav thiab kev tsim roj rov ua dua tshiab. Nrog nws cov qauv pore 3D 12-ring tshwj xeeb (6.6 × 6.7 Å), Beta Zeolite ua rau muaj kev ua haujlwm zoo tshaj plaws hauv kev hloov pauv molecule loj - ua tau zoo dua li cov catalysts ib txwm muaj txog li 40% hauv cov txheej txheem kev lag luam tseem ceeb.
Lub Ntsiab Cai Goldilocks: Vim Li Cas Beta Thiaj Tswj Tau Cov Kev Siv Cov Khoom Loj
Txawm hais tias cov zeolites me me (piv txwv li, ZSM-5) txwv tsis pub nkag mus thiab cov khoom siv loj dua txo qhov kev xaiv, Beta Zeolite cov qauv sib npaug muab:
Kev Hloov Pauv Zoo Tshaj Plaws: 3D cov channel sib tshuam ua rau cov molecules loj xws li cov roj nplua nyeem, cov roj bio, thiab cov roj polyaromatics
Qhov Acidity Tunable: SAR uas kho tau (10-100 mol/mol) tswj qhov ceev ntawm qhov chaw ua haujlwm rau qhov tshwj xeeb ntawm cov tshuaj tiv thaiv
Kev Ruaj Ntseg Hydrothermal: Tswj tau > 99% crystallinity ntawm 650 ° C / chav ua pa
Cov Kev Siv Hloov Pauv
✅ Kev Ua Kom Alkylation Hnyav
• Paraffin Alkylation: C8+ ntau dua 30% piv rau cov kua qaub, tshem tawm cov teeb meem HF/SO₂
• Kev Sib Xyaws Ua Los Ntawm Cov Roj Lubricant: Ua rau Pawg III cov roj tseem ceeb tsim tau nrog cov ntsuas viscosity >130
• Diesel Uas Rov Siv Tau Dua: Ua rau C18-C22 fatty acid alkylation ua rau cov roj biofuels poob qis
✅ Kev Ua Thawj Coj ntawm Hydrodeoxygenation (HDO)
Kev Ua Tau Zoo ntawm Daim Ntawv Thov Kev Txhim Kho Kev Lag Luam
Kev tshem tawm Lignin Depolymerization 90% oxygen tshem tawm $ 200 / ton bio-aromatics txo nqi
Kev Txhim Kho Roj Pyrolysis Ua Rau Muaj 40% Cov Khoom Siv Hydrocarbon Siab Dua Ua Rau Lub Chaw Ua Roj Sib Koom Tes Ua Haujlwm
Cov Qab Zib Biomass → Roj 5x lub neej ua haujlwm ntawm cov tshuaj catalyst piv rau Al₂O₃ OPEX qis dua 30%
Kev Tsim Kho Tshiab
[Lub Npe Tuam Txhab] cov kev hloov kho tshwj xeeb kov yeej cov kev txwv Beta ib txwm muaj:
Cov Qhov Hnyav
Mesopore (2-50nm) kev sib koom ua ke ua rau muaj kev sib kis sai dua 6 npaug
Pab kom ua tiav cov molecules >3nm (piv txwv li, triglycerides)
Kev Ua Haujlwm Hlau
Ni/Mo/Beta ua tiav 98% HDO kev ua haujlwm hauv cov reactors ib zaug dhau
Pt/Beta ua rau alkane isomerization selectivity nce mus txog 92%
Kev rov ua dua tshiab
100+ lub voj voog rov ua dua tshiab nrog <5% kev poob haujlwm
Muaj peev xwm ua kom coke oxidation hauv qhov chaw
Kev Kawm Txog Cov Ntaub Ntawv: Qhov Project Roj Dav Hlau Uas Rov Siv Tau Dua Tshiab
Ib tus khub koom tes loj hauv Tebchaws Europe tau ua tiav:
☑️ 99.2% deoxygenation ntawm cov roj ua noj pov tseg
☑️ Muaj peev xwm ua haujlwm tau 18,000 thoob/hnub tas li
☑️ $35M txuag tau txhua xyoo piv rau kev kho dej ib txwm muaj
*"Cov tshuaj catalysts uas siv beta txo peb qhov kub ntawm hydrotreating los ntawm 70°C, ua rau kev siv hydrogen tsawg dua."* - Tus Thawj Coj Saib Xyuas Kev Siv Tshuab
