2. Morphological models of a porous solid particle
A porous particle is made up of a fluid phase and a solid phase occupying respectively the volume fractions ε i and 1 – ε i where ε i is the particle's internal porosity.
This information is generally obtained using a mercury porosimeter, which can be used to determine not only ε i but also the pore diameter distribution of pores assumed to be circular cylindrical (figure 2 ).
