| Abstract | : | Conversion of n-butanol into 1,1-dibutoxybutane by using Fe/activated carbon (AC) catalyst has been done. This research was conducted by preparing 60-80 mesh activated carbon from coconut shell charcoal, then activated it at 850 °C for 4 hours using CO2 gas at flow rate of 10 mL/min. The activated carbon was then washed by acetone and HCl 1.0 M solution. Subsequently, the activated carbon was impregnated with 2?Cl3 and reduced for 3 hours at 650 °C using H2 gas at flow rate of 10 mL/min. The contents of Fe, Ca and Na in the activated carbon were determined using Atomic Absorption Spectroscopy (AAS). Characterization of the catalyst was conducted to determine the acidity of activated carbon and catalyst Fe/AC by gravimetric method using ammonia adsorption. The process of conversion reaction of n-butanol into 1,1-dibutoxybutane was carried out in an electric furnace by varying the temperature of 500, 550, and 600 °C, the mass of catalyst 10, 15, and 20 g, and H2 gas at flow rate of 5, 10, and 15 mL/min. Variations of experiments were conducted based on Taguchi method and produced nine variations of the experiment. Conversion reaction products were analyzed by FTIR, GC, GC-MS, 1H- NMR and 13C-NMR. The analysis showed that the activated carbon containing impurities such as Fe, Ca and Na metals. Washing activated carbon by acetone and HCl solution decreased the content of Fe, Ca, and Na metals significantly. Activated carbon acidity increased after Fe impregnation, from 6.490 mmol/g to 10.091 mmol/g. The highest conversion of n-butanol into 1,1-dibutoxybutane was 59.51%, based on Taguchi optimization at temperature of 550 °C, mass of catalyst 15 g, and H2 gas flow rate of 5 mL/min. |
