Investigation on hydrate formation from cyclopentane-loaded porous activated carbon particles

In this paper, the mechanisms of hydrate formation in presence porous activated carbon particles (PACP) loaded with cyclopentane (CP) and immersed an excess pure water are investigated using differential scanning calorimetry (DSC) combination gas porosimetry (GP) mercury intrusion (MIP). PACP different pore size distributions (PSDs) used CP hydrates formed at atmospheric pressure 1 °C. desorption from PACP, initially saturated or oversaturated CP, that is induced by crystallization studied quantifying amount CP-to-hydrates obtained and/or CP-conversion rate. It was found available for predominantly contained large pores on external surface PACP. Therefore, to enhance quantity formed, larger than a given threshold size, macroporous volume should be used. Moreover, shift observed equilibrium temperature shows fraction inside pores. The conclusions reached might offer new insights into hydrate-based processes.
