Mercury porosimetry (IMP) hysteresis loop scanning (SHL) data are used in t
he deduction of pore structure tomography diagrams. Macro and/or mese-pore
structure tomography refers to the tracing of intrinsic pore size distribut
ions (psd) of pore structure sections corresponding to specified volume sat
uration levels. Tomography information may be proved a useful tool e.g., to
elucidate mass transfer, heterogeneous reaction phenomena, etc. The contri
bution of the present work is the simulation of the MP scanning data, based
on the random corrugated pore structure model (CPSM), reported elsewhere a
nd the generation of the pertinent pore structure tomography spectra (i.e.,
a set of local, as regards saturation, intrinsic psd). The CPSM model has
been applied to carry out parametric studies for the generation of theoreti
cal loop scanning diagrams and the construction of the pertinent tomography
plots. Additionally the CPSM model have been successfully used in curve fi
tting applications by using experimental MP hysteresis loop scanning data,
taken from literature or produced in this work, and the deduction of the re
spective tomography diagrams. Part I of this work is devoted to pore struct
ure tomography accruing From MP loop scanning along the penetration line wh
ile Part II deals with loop scanning along the retraction curve and the der
ivation of the respective pore structure tomography spectrum. Overall, the
CPSM model simulates satisfactorily MP loop scanning data and yields credib
le pore structure tomography information.
