Abstract

Minyak kelapa sawit RBD ditukarkan kepada gasolin dengan mengalirkan wapnya melalui mangkin HZSM-5. Tiga sampel HZSM-5 dengan nisbah silika-alumina (SiO2/ Al2O3) yang berbeza iaitu 30, 50 dan 70 telah disediakan dan digunakan untuk mengkaji kesan nisbah silikaalumina HZSM-5 kepada proses tersebut. XRD telah digunakan untuk mengesahkan bahawa mangkin yang disediakan adalah HZSM-5. Analisis FTIR untuk spektra jarak sederhana dan spektra jarak dekat telah digunakan untuk memberi maklumat mengenai ciri-ciri struktur mangkin dan juga untuk menganalisa kumpulan hidroksil (OH) mangkin. Kesan nisbah silika-alumina dapat dilihat dengan jelas dari keputusan apabila HZSM-5 dengan nisbah silika-alumina 30 menghasilkan kepemilihan gasolin yang tinggi berbanding dengan dua mangkin yang lain. Kata kunci: Minyak kelapa sawit RBD, gasolin, HZSM–5, nisbah silika–alumina The RBD palm oil was converted to gasoline by passing its vapor through HZSMcatalyst. Three samples of HZSM-5 with different silica-alumina ratio (SiO2/ Al2O3) of 30, 50 and 70 were prepared and used to investigate the effect of silica-alumina ratio of HZSM-5 to the process. XRD was employed to confirm that the catalyst prepared were HZSM-5. FT-IR analysis for middle range spectra and near range spectra both were engaged to give structural characteristic of the catalyst and to analyze the hydroxyl (OH) groups of the catalyst respectively. The effect of silica-alumina ratio can be seen clearly from the result as HZSM-5 with 30 silica-alumina ratio produced the highest gasoline selectivity compare with the other two catalysts. Key words: RBD palm oil, Gasoline, HZSM–5, silica–alumina ratio
