We have carried out comprehensive GCMC molecular simulations to study the effects of temperature
(ranging from sub-critical to supercritical), cavity and neck dimensions, and adsorbate on the transition
from pore blocking to cavitation in slit shaped ink-bottle pores. Varying these parameters affects, not
only the position and the size of the hysteresis loop, but also its shape, which can change from H1, typical
for pore blocking, to H1 or H2 combined with Type C (in the de Boer classification). The combined loops
can either be fused loops or appear as two separate loops, one of which is of Type H1 and the other Type
C. Another highlight of our simulation study is the double maxima in the adsorption isotherm at a supercritical
temperature which results from the sigmoidal shape in the plot of bulk gas density versus pressure
and the compression of the adsorbate in the confined space at high pressures.
