Population Balance Modeling and Experimental Study of Crystallization and Particle Size Distribution in Hydrothermally Synthesized SAPO-۳۴

A population balance-based model was developed to investigate the crystallization kinetics of SAPO-۳۴ synthesized hydrothermally at ۲۰۰ and ۲۲۰ °C. The catalysts were characterized using XRD and DLS analyses. The model, formulated based on XRD data, incorporated kinetic expressions for homogeneous nucleation and diffusion-controlled growth and was implemented in a well-mixed batch system to predict crystal size distribution. The Grey Wolf Optimization technique was employed to solve the model equations. A strong correlation between experimental results and model predictions, particularly regarding mean crystal size, validated the model’s accuracy. This study underscores the significance of population balance modeling in understanding and optimizing zeolite crystallization processes, with potential implications for industrial applications such as catalysis, ion exchange, and adsorption.
