Daftar Isi:
- Preparation of Na / SBA-15 from corn leaves ash (Zea mays) as a substitute for TEOS (Tetraethyl Orthosilicate) applied as a heterogeneous catalyst in the transesterification reaction of used palm oil and methanol has been performed. The preparation of SBA-15 was conducted by surfactant template method and modification with Na was conducted by impregnation method. SBA-15 from corn leaves ash has a pore size ranging from 4.9 nm to 9.3 nm, a surface area of 595 m2/ g, a pore diameter of 3.95 nm and a pore volume of 0.99 cm3/ g. The yeild obtained from the first transesterification process was 96.46% with the free fatty acid content of the product 0.16 mg KOH/ g. The two most prominent methyl ester based on the chromatogram of the transesterification product, the two most prominent methyl ester in the product were methyl palmitate (36,32%) and methyl oleat (36,15%). Keywords : Maize, SBA-15, TEOS (Tetraethyl Orthosilicate), Transesterification of used palm oil
- Pembuatan silika mesopori Na/ SBA- 15 dari abu daun jagung (Zea mays) sebagai pengganti TEOS (Tetraethyl Orthosilicate) yang diaplikasikan sebagai katalis heterogen pada reaksi transesterifikasi minyak jelantah dan metanol telah dilakukan. Pembuatan SBA- 15 dilakukan dengan metode surfactant template dan modifikasi dengan Na dilakukan dengan metode impregnasi. SBA- 15 dari abu daun jagung memiliki ukuran pori berkisar 4,9 nm – 9,3 nm, luas permukaan 595 m2/g, diameter pori 3,95 nm dan volume pori 0,99 cm3/g. Aplikasi penggunaan katalis Na/ SBA- 15 pada proses transesterifikasi pertama diperoleh persen rendemen 96,46% dengan kadar asam lemak bebas 0,16 mg KOH/gr. Komposisi metil ester dominan berdasarkan hasil analisa GC-MS adalah metil palmitat 36,32% dan metil oleat 36,15%.
