Abstract
This research aims to modify HZSM-5, Mordenite, and Silica Alumina with Fe metal as a catalyst for oleic acid cracking reaction to fuel oil. This research was used impregnation method to modify HZSM-5, Mordenite, and Silica Alumina with Fe metal and fluid catalytic cracking (FCC) method to convert oleic acid into fuel. The characteristics of the catalyst samples were analyzed using X-Ray Fluorescence, X-Ray Diffraction, Fourier Transformed Infrared Spectroscopy, Ammonia-Temperature Programmed Desorption, Surface Area Analyzer, dan Hydrogen-Temperature Programmed Reduction technigue. The produced-liquid was analyzed using Gas Chromatography Mass Spectrometry technigue.
The results showed that Modification of HZSM-5, Mordenite, and Silica Alumina with Fe Metal had increased the average of crystal size, the pore volume, and the average pore size. However, the Fe metal modification had decreased the total acid site, the crystallinity, and the surface area. The catalysts produced in this research were HZSM-5, Fe3/HZSM-5, Fe6/HZSM-5, Fe9/HZSM-5, Mordenite, Fe3/Mordenir- Fe6/Mordenite- Fe9/Mordenite, Silica Alumina, Fe3/Silica Alumina, Fe6/Silica Alumina, and Fe9/Silica Alumina catalysts with the ability to convert oleic acid were 98.93- 98.48- 99.00- 97.68- 99.29- 97.83- 97.40- 97.99- 98.58- 98.76- 98.40: and 98.18%, respectively.
Keywords: catalyst, Fe Metal, cracking, oleic acid, fuel oil.
