Abstract

Silika mesopori (MS) telah berhasil disintesis dengan template lerak (Sapindus Rarak) sebagai katalis dan diaplikasikan pada reaksi deoksigenasi. Sintesis silika mesopori dilakukan dengan metode hidrotermal pada suhu 100 °C. Ekstrak buah lerak ditambahkan dengan variasi perbandingan (TEOS:ekstrak lerak) 1:0,5, 1:1, dan 1:2 (w/w). Hasil karakterisasi Fourier Transform Infrared (FTIR) menunjukan gugus siloksan (Si-O-Si) dan silanol (Si-OH) pada bilangan gelombang 1000–1300 cm-1 dan 3400–3600 cm-1 yang merupakan gugus khas silika mesopori. SEM dan TEM produk yang dihasilkan memiliki morfologi yang tidak teratur menunjukkan bahwa material yang dihasilkan adalah silika mesopori. X-ray Diffraction (XRD) menunjukkan terbentuknya silika mesopori. Karakterisasi dengan adsorpsi-desorpsi N2 menunjukkan isoterm adsorpsi tipe IV H1 yang mengindikasikan terbentuknya mesopori. Luas permukaan mesopori dan volume mesopori tertinggi diperoleh pada material MS-L1 sebesar 478 m2/g dan 0,57 cc/g. MS hasil reaksi digunakan untuk uji katalitik reaksi deoksigenasi minyak goreng bekas pada suhu 350 °C dan waktu reaksi 4 jam. Hasil reaksi menunjukkan selektivitas hidrokarbon tertinggi pada MS-L1 sebesar 80,60%.

Mesoporous silica (MS) has been successfully synthesized with lerak template (Sapindus Rarak) as a catalyst and applied to deoxygenation reactions. The synthesis of mesoporous Silica was carried out by the hydrothermal method at a temperature of 100 °C. Eextract of lerak fruit was added with variations in the ratio (TEOS:lerak extract) of 1:0.5, 1:1, dan 1:2 (w/w). The results of the Fourier Transform Infrared (FTIR) characterization showed siloxane groups (Si-O-Si) and silanol (Si-OH) at wave numbers 1000–1300 cm-1 and 3400–3600 cm-1 which are typical clusters of mesoporous silica. The resulting SEM dan TEM products have irregular morphology indicating that the resulting material is mesoporous silica. X-ray Diffraction (XRD) shows the formation of mesoporous silica. Characterization by adsorption-desorption N2 indicates an adsorption isotherm of type IV H1 indicating the formation of mesoporous. The highest mesoporous surface area dan mesoporous volume were obtained in MS-L1 material of 478 m2/g dan 0.57 cc/g. The MS reaction results were used for catalytic testing of the deoxygenation reaction of used cooking oil at a temperature of 350 °C dan a reaction time of 4 hours. The reaction results showed the highest hydrocarbon selectivity in MS-L1 at 80.60%.
