•Different shapes and sizes of hysteresis loop have been observed for a set of pore with different sequences of connectivity.•The adsorption in one section of the pore is affected significantly by the state of the adjacent pores.•The presence and the position of the closed ends affect significantly the shape and size of the hysteresis loop.•Pore size distribution calculated using kernel of isotherms of independent open pores may be incorrect for connected pores.
We present a simulation study to investigate the significance of connectivity on the adsorption isotherm, for a collection of connected pores. By examining different sequences of connectivity in a set of three cylindrical sections of different sizes, we have been able to obtain adsorption isotherms with a variety of shapes and sizes of hysteresis loop; none of which can be reproduced by combining isotherms of the individual pores with two open ends. We conclude that there is a need to re-examine the choice of kernel in the determination of pore size distributions for systems with interconnected pore spaces.
