What are the effects of changing the shape or dimensions or pore size on the particle density of a solid?

Particles of Adsorbents and catalysts are available in different shapes like granules, powder, spheres, beads, cylinders, lobes,etc.


They are also available in different sizes and different pore sizes ranging from microporous to mesoporous. Which of these will have the most significant effect on the particle density?What are the effects of changing the shape or dimensions or pore size on the particle density of a solid?
Experimental and theoretical investigations indicate particle shape and size influence biomass particle dynamics, including drying, heating rate, and reaction rate.
