Abstract

Peningkatan permintaan penerbangan global mendorong kebutuhan terhadap bahan bakar penerbangan yang lebih berkelanjutan. Sustainable Aviation Fuel (SAF) berbasis minyak non-pangan merupakan salah satu solusi yang menjanjikan karena potensinya dalam mengurangi emisi karbon secara signifikan. Penelitian ini bertujuan untuk memproduksi SAF dari minyak biji kesambi (Schleichera oleosa) melalui reaksi deoksigenasi dengan katalis Ni/Sodalit, serta mengkaji pengaruh variasi loading nikel sebesar 2,0; 4,0; dan 8,0% b/b terhadap konversi minyak biji kesambi menjadi hidrokarbon rentang SAF. Material penyangga sodalit disintesis melalui metode hidrotermal dengan kaolin dan natrium aluminat sebagai sumber Si dan Al. Katalis Ni/Sodalit disiapkan melalui metode impregnasi basah diikuti dengan reduksi hidrazin hidrhat. Katalis dikarakterisasi dengan X-Ray Diffraction (XRD) dan Fourier Transform Infrared Spectroscopy (FTIR) untuk mendukung interpretasi kinerja katalitiknya pada reaksi deoksigenasi. Karakterisasi XRD mengonfirmasi terbentuknya fasa sodalit dan Ni⁰ pada seluruh variasi loading, dengan ukuran kristalit sodalit yang meningkat seiring bertambahnya loading Ni. Analisis FTIR dan XRD menunjukkan bahwa kerangka sodalit tetap terjaga setelah impregnasi nikel. Minyak biji kesambi yang telah melalui proses degumming digunakan sebagai bahan baku reaksi deoksigenasi yang dilakukan dalam reaktor batch pada temperatur 300°C, tekanan H2 awal 5 bar, selama 2 jam. Hasil reaksi deoksigenasi dianalisis dengan Gas Chromatography-Mass Spectrometry (GC-MS). Konversi minyak biji kesambi menjadi hidrokarbon SAF meningkat seiring bertambahnya loading Ni, dimana hasil optimum diperoleh pada penggunaan katalis Ni/Sodalit loading 8,0% b/b dengan konversi 95,22%.

The increasing global demand for air transportation has driven the need for more sustainable aviation fuels. Sustainable Aviation Fuel (SAF) derived from non-edible oils is considered one of the most promising alternatives due to its significant potential for reducing carbon emissions. This study aimed to produce SAF from kesambi seed oil (Schleichera oleosa) through a deoxygenation reaction using Ni/Sodalite catalysts and to investigate the effect of nickel loading variations of 2.0, 4.0, and 8.0% b/b on the conversion of kesambi seed oil into SAF-range hydrocarbons. The sodalite support was synthesized using a hydrothermal method with kaolin and sodium aluminate as the silicon and aluminum sources. Ni/Sodalite catalysts were prepared via the wet impregnation method followed by hydrazine hydrate reduction. The catalysts were characterized using X-ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) to support the interpretation of their catalytic performance in the deoxygenation reaction. XRD characterization confirmed the formation of sodalite and metallic Ni⁰ phases at all nickel loadings, with the sodalite crystallite size increasing as the nickel loading increased. FTIR and XRD analyses further indicated that the sodalite framework remained intact after nickel impregnation. Degummed kesambi seed oil was used as the feedstock for the deoxygenation reaction, which was carried out in a batch reactor at 300°C under an initial H₂ pressure of 5 bar for 2 hours. The deoxygenation products were analyzed using Gas Chromatography–Mass Spectrometry (GC–MS). The conversion of kesambi seed oil into SAF-range hydrocarbons increased with increasing nickel loading, with the optimum performance achieved using the 8.0% b/b Ni/Sodalite catalyst, resulting in a conversion of 95.22%.
