Abstract
This work is devotcd to thc authenticity examination of porc size distributions which are result of some convcntional interpretation techniqucs for indepcndcnt porcs. Thc prcsenl investigation is bascd on computcr cxpcrimcnts simulating adsorption, capillary condcnsation, dcsorption, mercury intrusion and sonic olhcr proccsscs in modcl porous latlicc made up of a largc number of sphcroidal-shapcd voids pastcd togcthcr by toroidal-shapcd necks. Spccial atlcntion has been paid to plausibility of simulating proccsscs. In particular, thc cooperative capillary condcnsalion inside the group of neighbouring voids has bccn analyzcd in terms of thermodynamics and molecular physics. The results of long-duration numerical cxpcriments ( adsorption isotherms, mercury intrusion curves, etc.) have been proccsscd with thc help of conventional techniques calculating indepcndent pore size distributions. Sizc distributions obtaincd this way havc bccn compared with those generated for corresponding modcl porous solids, the reasons of mismatches havc been also analyzed. Conclusions conccrning with morc rcliablc intcrpretation of rcsults obtaincd by traditional techniques havc bccn made.
