Alkaline Na2CO3 fusion was firstly used as an activation methodology to improve the exhausted fluid catalytic cracking catalyst conversion to NaA zeolite. Synthesis experiments were performed varying the catalyst/ Na2CO3 weight ratios and the heating treatment. X-ray diffraction analysis was used to identify the different crystalline phases present in the starting material as well as in the products. Quantitative determinations of crystalline phases were performed by Rietveld analysis. Particle sizes and morphologies were observed by electronic scanning microscopy. It was shown that the proposed activation methodology allows high crystallization rates and good conversion in NaA zeolite.
