Type: article
Abstract: Adsorption-based separation technology has emerged as a promising method for capturing carbon dioxide (CO2) from natural gas. The application of ultrasonic-aided pretreatment prior to hydrothermal heating appears to be a viable alternative in promoting rapid synthesis for porous structures. In the present research, Gismondine (GIS) zeolite were synthesized via ultrasonic-aided hydrothermal growth method to reduce the formation duration of zeolite. The ultrasonic-aided pretreatment period were varied from 30 min to 90 min and hydrothermal growth durations were manipulated from 1 day to 5 days. The resulting GIS zeolites were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR). As verified by XRD, SEM and FTIR, the samples synthesized via ultrasonic-aided pretreatment of 60 min and 90 min exhibited GIS zeolite crystal structure. Furthermore, the application of ultrasonic-aided pretreatment has successfully accelerated the formation of GIS zeolite to 2 days as compared to 7 days required by the conventional hydrothermal growth method.
