This study was conducted to evaluate the effect of crystallization time on structure, microstructure, and catalytic activity of zeolite-A synthesized from rice husk silica (RHS) and food-grade aluminum foil. Four samples were prepared with fixed crystallization temperature of 100 °C and crystallization time of 48, 72, 96, and 120 h respectively, followed by calcination treatment at 550 °C for 6 h. The structure of the samples was evaluated using XRD and microstructure using SEM. For catalytic activity assessment, the zeolites were used in pyrolysis of mixed ground cassava tuber (GCT) and palm oil. The liquid fuels from the pyrolysis experiments were analyzed using GC-MS technique to identify the chemical composition of the liquids. Characterization using XRD technique revealed that zeolite-A has been produced at 48 hour crystallization period and no significant change of the structure resulted with extension of crystallization time. Quite a significant effect of crystallization time on surface morphology of the samples as seen by SEM, was observed, with the most evident are the shape and size of the particles. The liquid fuels produced were found to contain hydrocarbon as the main component, with relative percentage in the range of 85 to 92%,suggesting that synthesized zeolites are promising catalyst for biogasoline production.
