This kinetic parameter correlates well with the secondorder rate constants for water diffusion in the pores (p < 0,01). It is concluded that xc is by itself a sufficient parameter for comparison of mass-transfer resistance between different candidate supports.engacceso abiertoSCIENTIFIC EQUIPMENTDRYINGEVALUATIONMATERIALSDrying kinetics as Tool for the Assessment of Dynamic Porosity of Catalyst-Support MaterialsartÃculo original10.5171/2018.901967
