Abstract

Experimental water intrusion–extrusion isotherms were performed at room temperature on mesoporous silicalite-1 samples, prepared in fluoride medium and using carbon black or surfactant, [3-(trimethoxysilyl)propyl]hexadecyldimethylammonium chloride, as porogen and templating agents, respectively. The increase of the porous volume observed for the silicalite-1 sample prepared in the presence of carbon black leads to an increase of the water intruded volume at high pressure (100 MPa). Therefore, the amount of stored energy in this water–zeolite system is greater than for a conventional “water–silicalite-1” system. However, the fluoride route appears to be a less effective method than the alkaline route.
