Herliana published the artcileTransesterification of coconut oil (Cocos nucifera L.) into biodiesel using zeolite-A catalyst based on rice husk silica and aluminum foil, SDS of cas: 111-11-5, the main research area is Cocos zeolite aluminum foil biodiesel transesterification.
In this research, zeolite-A was synthesized by hydrothermal method using silica of rice husk and aluminum foil as raw materials. For zeolite preparation, a particular amount of silica was dissolved in NaOH solution which is then aged with variation time of 24-96 h, the mixed solution was then added with aluminum foil and again aged for 24 h, the crystallization process was carried out in an oven of 100°C 96 h. The resulting zeolite was then calcined at 550°C for 6 h. The zeolite characterization by XRD showed that zeolite-A had been formed and had characteristics following the zeolite-A standard from IZA. The resulting zeolite-A has good crystallinity as indicated by the sharp peaks on the resulting diffractogram. The zeolite-A catalytic test on transesterification of coconut oil showed high catalyst performance, characterized by the conversion of fatty acids in coconut oil to Me esters with 100% conversion percent. The formation of the Me ester was proven based on the results of the anal. with FTIR and GCMS which showed the characteristics of Me ester at wavenumbers 1744 cm-1 (C=O), 2922 cm-1 (C-H), 1170 cm-1 (C-O), with the highest percentage in the form of Me laurate at 31.80%.
