Abstract

Aluminosilkat mesopori disintesis dengan variasi logam Ni, La, dan Ce kombinasi dual-template Pluronic (P123) dan microcrystalline cellulose (MCC) untuk mengetahui pengaruh variasi logam terhadap karakteristik material dan aktivitas katalitiknya pada reaksi deoksigenasi minyak nyamplung. Sintesis aluminosilikat dilakukan dengan kombinasi metode sol-gel dan hidrotermal dengan perbandingan P123:MCC yaitu 1:1. Selanjutnya, dilakukan impregnasi nikel pada pendukung aluminosilikat dengan metode ultrasonik. Variasi jenis logam yang diimpregnasikan memberikan pengaruh terhadap struktur, morfologi, dan aktivitas katalitik material. Hasil karakterisasi X-ray Diffraction (XRD) menunjukkan adanya fasa Ni dengan struktur kubik berpusat muka dan fasa La2O3 pada katalis 5%Ni-La/Al-MS. Citra Field Emission Scanning Electron Microscope-Energy Dispersive X-ray (FESEM-EDX) menunjukkan morfologi sferis (bola) dengan ukuran partikel rata-rata 1,719 µm. Adsorpsi-desorpsi N2 mengindikasikan sifat mesopori yang terbesar pada 5%Ni-La/Al-MS dengan luas permukaan spesifik, volume, dan diameter pori berturut-turut terbesar pada 5%Ni-La/Al-MS sebesar 216,35 m2/g; 0,278 m3/g; 3,866 nm. Katalis 5%Ni-La/Al-MS menunjukkan aktivitas terbaik dalam reaksi deoksigenasi minyak nyamplung, menghasilkan yield produk cair sebesar 64,65% dan konversi minyak nyamplung 84,63% pada suhu 380 ℃ selama 2 jam. Hasil ini menunjukkan bahwa modifikasi jenis logam berpengaruh signifikan terhadap kinerja katalis dan 5%Ni-La/Al-MS berpotensi untuk dikembangkan lebih lanjut sebagai katalis biofuel.

Mesoporous aluminosilicates were synthesized with variations of Ni, La, and Ce metals in a dual-template combination of Pluronic (P123) and microcrystalline cellulose (MCC) to determine the effect of metal variations on material characteristics and catalytic activity in the deoxygenation reaction of nyamplung oil. Aluminosilicate synthesis was carried out by a combination of sol-gel and hydrothermal methods with a ratio of P123:MCC of 1:1. Furthermore, nickel impregnation was carried out on the aluminosilicate support by ultrasonic method. Variations in the type of metal impregnated affect the structure, morphology, and catalytic activity of the material. X-ray Diffraction (XRD) characterization results showed the presence of Ni phase with face-centered cubic structure and La2O3 phase in 5%Ni-La/Al-MS catalyst. Field Emission Scanning Electron Microscope-Energy Dispersive X-ray (FESEM-EDX) images showed a spherical morphology with an average particle size of 1.719 µm. Adsorption-desorption of N2 indicated the largest mesoporous properties at 5%Ni-La/Al-MS with the largest specific surface area, volume, and pore diameter at 5%Ni-La/Al-MS of 216.35 m2/g; 0.278 m3/g; 3.866 nm, respectively. The 5%Ni-La/Al-MS catalyst showed the best activity in the deoxygenation reaction of nyamplung oil, producing liquid product yield of 64.65% and conversion of nyamplung oil of 84.63% at 380 ℃ for 2 hours. These results indicate that metal type modification has a significant effect on catalyst performance and 5%Ni-La/Al-MS has the potential to be further developed as a biofuel catalyst.
