Cool, N. Maes, I. Heylen, M. de Bock, E. Vansant] Pillared Clays are proposed as a new class of sorbents with properties which exceed those of zeolites. However, despite of intense research, the materials are still not used as substituents of zeolites. By the present study a better understanding of the potential and limiting factors of pillared clays is achieved by means of geometric models. These models take into account interlayer distance, pillar symmetry, collapse, partial pillaring, layer size and layer stacking. The results are evaluated on microporosity and interpillar distance and compared to experimental data. Because of the important contribution of mesopores to the pore volume of PILCs, a macrostructure in which the experimental mesopore volume has been approximated, is proposed. This paper reports the evaluation of two Al-pillared hectorites, natural and synthetic (laponite), having completely different macrostructures.
