| Popis: | The prodigious ashes frompower electricity generation plants were devastated as solid waste by palmindustries into environment. PIAW, mostly Palm Oil Fuel Ash (POFA) comprisingsilica and alumina was discarded as non-profit oriented products, thus thiswork is about PIAW, essentially POFA derived zeolites using ultrasound irradiation.Performance of POFA was characterized, and process optimization was done byemploying CCD. Pre-treated POFA as feedstock and formed zeolites weredesignated and analyzed using X-Ray Fluorescence (X-RF), Scanning ElectronMicroscopy (SEM) images, Fourier Transform Infrared (FTIR) spectrum and X-RayDiffraction (XRD) diagram. Alkaline concentration (0.6 M-1.4M), irradiationtime (140 min-160 min) and KOH/POFA (1.5:1-2.5:1) were examined as non-constantvariables. Otherwise, ultrasonic power (600W), temperature (80°C) and silicaalumina ratio were justified as constant and response variables. An optimalsynthesized zeolites as ratio of SiO2 and Al2O3(10.60) was found from surface plot based on quadratic typical at KOH=1 M,KOH/POFA=2 and time=150 min. Presence of A, P, X and irregular shape structureszeolites are commensurable to another resources, mainly fly ash. These findingsare also important for waste reduction, recycling and zeolites synthesis frommaterial under economic value. |
