  • Granulated inorganic sorbent and method of its manufacture
    Patent number: 5190907
    Abstract: A granulated inorganic sorbent having the formula:Ti.sub.x Zr.sub.y Sn.sub.1-x-y O.sub.2.nH.sub.2 Owhere 0<x+y<1, x=0-0.95, y=0-0.15, n=0.05-1.8, has a specific surface of 30-250 m.sup.2 /g and represents a solid solution with a rutile type structure characterized by principal peaks at the angle 2.theta. equal to 26.8.+-.0.7, 34.5.+-.1.5, 52.8.+-.1.5 degrees.The method of its manufacture comprises electrolysis of an aqueous solution containing tin chloride, titanium chloride and/or zirconium chloride at a molar ratio Ti:Zr:Sn=(0-0.95):(0.0.15):(0.03-1.0), followed by dropwise dispersion of the formed sol in a gelling liquid at pH.gtoreq.12 and heat treatment of the gel particles at a temperature within 20.degree. to 900.degree. C.
