Pratama, SafrenoPanggih (2014) Studi Reaksi Hidrogenasi Terhadap Furfural Menggunakan Katalis Ni/γ-Al2O3. Sarjana thesis, Universitas Brawijaya.
Abstract
Hidrogenasi selektif terhadap furfural menjadi produk alkohol telah dilakukan menggunakan katalis Ni/γ-Al2O3. Beberapa tahapan dalam penelitian ini adalah preparasi katalis Ni/γ-Al2O3, karakterisasi katalis, dan reaksi hidrogenasi katalitik. Karakterisasi katalis dilakukan menggunakan X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), dan Atomic Absorption Spectrometry (AAS) sedangkan produk hasil reaksi hidrogenasi dianalisis menggunakan Fourier Transform Infrared Spectroscopy (FTIR). Berdasarkan analisis menggunakan XRD dan SEM, diketahui bahwa logam Ni telah terimpregnasi pada γ-Al2O3 tanpa menunjukan keberadaan NiO. Analisis menggunakan AAS berguna untuk mengetahui kadar Ni dalam katalis Ni/γ-Al2O3 yaitu sebesar 9,96%. Reaksi hidrogenasi dilakukan pada temperatur 150 dan 180 °C selama 1; 2; 2,5; dan 3 jam dalam kondisi atmosfer hidrogen. Konversi furfural terbaik dihasilkan pada temperatur reaksi 180 °C selama satu jam sebesar 53,22%. Kondisi reaksi terbaik pada pembentukan produk alkohol pada temperatur reaksi 150 °C selama tiga jam dengan selektivitas terhadap produk alkohol sebesar 81,62%.
English Abstract
The selective hydrogenation of furfural into alcohol product has been carried out using the Ni/γ-Al2O3 catalyst. Several stages in this study are preparation of the Ni/γ-Al2O3 catalyst, catalyst characterization, and catalytic hydrogenation reactions. Catalyst characterization was performed using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Atomic Absorption Spectrometry (AAS) while hydrogenation reaction products were analyzed using Fourier Transform Infrared Spectroscopy (FTIR). Based on analysis using XRD and SEM, is known that the Ni metal was impregnated on γ-Al2O3 without showing the presence of NiO. Analysis using AAS determine content of Ni in the Ni/γ-Al2O3 catalyst is equal to 9.96%. Hydrogenation reactions carried out at a temperature of 150 and 180 °C for 1; 2; 2,5; and 3 hours in a hydrogen atmosphere conditions. Best furfural conversion reaction occurs at a temperature of 180 °C for one hour with 53,22% conversion of furfural. The best selectivity over alcohol product is 81,62% occurs at a temperature of 150 °C for three hours.
