Abstract

Three samples taken from a silica gel Hypersil were hydrothermally treated, washed and dried under different conditions. The portions from the obtained samples were heated over a temperature range of 300 and 850 °C for 16 h. Surface area and pore volume all of the treated samples were respectively determined by nitrogen adsorption data at 77 K and mercury porosimetry. The volumetric flow rate and permeability of the isopropyl alcohol on the columns filled with the prepared samples were determined depending both the inlet pressure and packing pressure. The optimum conditions to prepare a column filling materials with the heights permeability were discussed.
