Abstract:
An olefin selective adsorbent using copper-based complex metal chloride is provided to manufacture an adsorbent showing the quantity of adsorbed olefin and selectivity equal to those of a silver-ion impregnated adsorbent. An olefin selective adsorbent is an adsorbent for absorbing/separating olefin from olefin/paraffin compound. Ferric chloride(FeCl2) of 5 through 29.9 wt% and cupric chloride(CuCl) of 5 through 23.4wt% are dipped into a substrate in which specific surface area is 100 m^2/g or greater. The substrate having large specific surface area is selected from MCM-41, MCM-48, SBA-15, SBA-16 and KIT-6 which are aluminosilica gel, silica gel, alumina and middle-sized porous silica.

Abstract:
PURPOSE: A method for preparing mesosilica template(HP-KIT-6) with high hydrophobicity using cubic mesoporous silica tample is provided. CONSTITUTION: A method for preparing highly ordered mesoporous silver comprises: a step of impregnating solution containing silver nitrate(Ag(NO3)), ethanol, and distilled water into hydrophobic mesoporous silica template(HP-KIT-6) to form silver impregnated material; a step of drying the silver impregnated material and heating under the presence of nitrogen; a step of treating with NaOH solution to remove silica template; and a step of washing with distilled water and acetone and drying.
