Abstract

Penelitian ini bertujuan untuk mensintesis dan uji aktivitas katalis Co/Sodalit dengan variasi loading kobalt sebesar 2, 4, dan 8 wt% untuk produksi SAF melalui reaksi deoksigenasi minyak biji kesambi. Sodalit disintesis secara hidrotermal dari kaolin alam, sedangkan katalis Co/Sodalit disiapkan melalui metode impregnasi basah. Katalis dikarakterisasi dengan X-Ray Diffraction (XRD) dan Fourier Transform Infrared (FTIR). Hasil XRD mengonfirmasi terbentuknya fasa sodalit dari kaolin alam, dan analisis persamaan Scherrer menunjukkan ukuran kristalit yang semakin besar seiring peningkatan loading kobalt. Spektra FTIR mengkonfirmasi keberhasilan sintesis sodalit. Reaksi deoksigenasi dilakukan pada suhu 300 °C, tekanan awal H2 sebesar 5 bar, waktu reaksi 2 jam, dan kecepatan pengadukan 400 rpm. Hasil reaksi dianalisis menggunakan GC-MS. Hasil penelitian menunjukkan bahwa katalis Co/Sodalit berhasil mengkonversi minyak biji kesambi menjadi hidrokarbon alkana dengan rentang C9-C18 yang termasuk dalam spesifikasi SAF. Konversi yang diperoleh pada loading kobalt 2,0; 4,0; dan 8,0 wt% sebesar 63,02% ; 88,41; dan 97,42%. Penelitian ini menunjukkan bahwa katalis Co/Sodalit berbasis kaolin alam merupakan katalis yang potensial dan ekonomis untuk produksi SAF dari minyak biji kesambi.

This study aimed to synthesize and test the activity of Co/Sodalite catalysts with cobalt loading variations of 2, 4, and 8 wt% for the production of Sustainable Aviation Fuel (SAF) through the deoxygenation of kesambi seed oil. Sodalite was synthesized hydrothermally from natural kaolin, while the Co/Sodalite catalysts were prepared using the wet impregnation method. The catalysts were characterized by X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy. The XRD results confirmed the formation of the sodalite phase from natural kaolin, and analysis using the Scherrer equation indicated that the crystallite size increased with increasing cobalt loading. The FTIR spectra further confirmed the successful synthesis of sodalite. The deoxygenation reaction was carried out at a temperature of 300 °C, an initial H2 pressure of 5 bar, a reaction time of 2 hours, and a stirring speed of 400 rpm. The reaction products were analyzed using gas chromatography–mass spectrometry (GC-MS). The results showed that the Co/Sodalite catalysts successfully converted kesambi seed oil into C9–C18 alkane hydrocarbons, which fall within the SAF specification range. The conversions obtained at cobalt loadings of 2.0, 4.0, and 8.0 wt% were 63.02%, 88.41%, and 97.42%, respectively. These findings indicate that natural kaolin-based Co/Sodalite catalysts are promising and cost-effective catalysts for SAF production from kesambi seed oil.
