Zusammenfassung: | The purpose of this study was to determine the effectiveness of the conversion of glycerol into ethanol using an Ag-Zn/ZSM-5 catalyst with ultrasonic assistance at a temperature of 60 oC with variations in sonication time of 2 hours, 4 hours, and 6 hours. This research was carried out in 4 stages, namely: (1) activation of ZSM-5 with NH4Cl, (2) Impregnation of Ag metal, Zn metal and a mixture of Logan Ag and Zn metal, (3) Characterization of ZSM-5 catalyst resulting from activation and impregnation, (4) ultrasonic-assisted conversion of glycerol to ethanol with time variations. The characterization of the catalyst used XRF, XRD, acidity and surface area analysis, while the GC tool was used to analyze the results of the conversion of glycerol into ethanol. The results showed that the Zeolite ZSM-5 was successfully impregnated with a mixture of Ag and Zn metals as evidenced by XRD analysis, namely that there was a similarity of peaks at an angle of 2θ with the JCPDS standard and the results of XRF analysis were obtained that impregnated Ag and Zn metals were 13.3 wt% and 10.7 wt%. Optimum degradation time for glycerol conversion glycerol to ethanol using Ag-Zn/ZSM-5 catalyst with ultrasonic assistance at a temperature of 60 oC is 4 hours with a yield of 45 wt%. |
