<p>PURPOSE:To increase the adsorption characteristics of acetaldehyde by forming the oxide and hydroxide of one and two or more kinds of elements selected among groups I a, IIa, IIIa, IVa, Va elements and transition elements of the periodic table on the surface or to the inside of the narrow pores of activated carbon. CONSTITUTION:An aq. soln. or an alcoholic soln. of oxide, hydroxide or both the two of one and two or more kinds of the following elements is made wherein the elements are selected among group I a elements of the periodic table consisting of Li, Na, K; group IIa elements consisting of Mg, Ca; group IIIa elements consisting of B, Al; group IVa elements consisting of Si, Sn; group Va elements consisting of P and transition elements consisting of Ti, Zr plus Cu. After these are mixed with activated carbon and impregnated on the surface, to the inside of the narrow pores or to both the two, these are fixed on the surface, to the inside of the narrow pores or to both by drying the activated carbon.</p> |
