I-Catalyst Ethuthukisiwe Ivula Ukusebenza kahle ku-Alkylation kanye Nokuthuthukiswa Kwe-Bio-Oil
Umsunguli ohamba phambili wama-molecular sieve namuhla umemezele ukuphumelela kwezicelo zama-catalysts akhe e-Beta Zeolite, axazulula izinselele ezibucayi ekucutshungulweni kwe-hydrocarbon esindayo kanye nokukhiqizwa kukaphethiloli ovuselelekayo. Ngesakhiwo sayo esiyingqayizivele se-3D 12-ring pore (6.6×6.7 Å), i-Beta Zeolite inika amandla ukusebenza kahle okungakaze kubonwe ekuguqulweni kwama-molecule amakhulu - idlula ama-catalysts avamile ngokufika ku-40% ezinqubweni ezibalulekile zezimboni.
Umgomo We-Goldilocks: Kungani I-Beta Ibusa Izicelo Ze-Large-Molecule
Ngenkathi ama-zeolite anezimbotshana ezincane (isb, i-ZSM-5) ekhawulela ukufinyelela kanye nokukhetha kokudela okukhulu kwe-pore, ukwakheka okulinganiselwe kwe-Beta Zeolite kuyaletha:
I-Optimal Mass Transfer: Iziteshi eziphambanayo ze-3D zithatha ama-molecule amakhulu njengamafutha, amafutha e-bio, nama-polyaromatics.
I-Tunable Acidity: I-SAR eguquguqukayo (10-100 mol/mol) ilawula ukuminyana kwesayithi okusebenzayo ukuze kucace ukusabela
Ukuzinza kwe-Hydrothermal: Igcina ukucwebezela okungu->99% ku-650°C/indawo yomusi
Izicelo Eziguqulayo
✅ Ukuphumelela kwe-Alkylation Enzima
• Upharafini Alkylation: 30% isivuno esiphezulu se-C8+ uma siqhathaniswa nama-acid awuketshezi, aqeda izingozi ze-HF/SO₂
• I-Lubricant Synthesis: Inika amandla ukukhiqizwa kwamafutha esisekelo se-Group III anezinkomba ze-viscosity >130
• Udizili Ovuselelekayo: Icubungula i-C18-C22 fatty alkylation yama-biofuels okwehla
✅ Ubuholi be-Hydrodeoxygenation (HDO).
Ukusebenza Kwesicelo Kuzuza Umthelela Wezomnotho
I-Lignin Depolymerization 90% yokususwa komoyampilo $200/ton yokunciphisa izindleko ze-bio-aromatics
I-Pyrolysis Oyela Ukuthuthuka ngo-40% isivuno esiphezulu se-hydrocarbon Inika amandla ukucutshungulwa ngokubambisana
I-Biomass Sugars → I-Fuels 5x catalyst lifetime vs. Al₂O₃ 30% ephansi OPEX
Ubunjiniyela obusha
Ukuguqulwa kobunikazi be-[Igama Lenkampani] kunqoba imikhawulo ye-Beta evamile:
Izimbotshana ze-Hierarchical
Ukuhlanganiswa kwe-Mesopore (2-50nm) kusheshisa ukusabalalisa ngo-6x
Inika amandla ukucubungula > kwama-molecule angu-3nm (isb, ama-triglycerides)
Metal-Ukusebenza
I-Ni/Mo/Beta ifinyelela ukusebenza kahle kwe-HDO okungu-98% kumareactor anephasi elilodwa
I-Pt/Beta ithuthukisa ukukhetha kwe-alkane isomerization ukuya ku-92%
Ukukhiqiza kabusha
Imijikelezo yokuvuselela engu-100+ ngokulahleka komsebenzi okungu-<5%.
Amandla we-in-situ coke oxidation
Isibonelo: Iphrojekthi Yezibaseli ZeJet Evuselelekayo
Uzakwethu omkhulu wezamandla wase-Europe uzuziwe:
☑️ 99.2% deoxygenation yamafutha okupheka emfucuza
☑️ 18,000 imiphongolo/usuku lokusebenza okuqhubekayo
☑️ $35M ukonga konyaka uma kuqhathaniswa ne-hydrotreating evamile
*”Ama-catalyst asekelwe ku-Beta anciphise izinga lokushisa lethu le-hydrotreating ngo-70°C, anciphisa ukusetshenziswa kwe-hydrogen.”* – Isikhulu Esiyinhloko Sezobuchwepheshe
