INORGANIC COBALT ADSORBENT AND ITS PRODUCTION

摘要

PURPOSE:To prevent the shape crumbling of the titled adsorbent in under-water and to improve the maintenance of the mechanical strength by molding the cobalt adsorbent from a molded body of titania hydrate and/or titanium oxide contg. titania short fiber. CONSTITUTION:Titania sol is mixed uniformly and dispersively with a mixture of the titania short fiber and the titania particles and this mixture is molded. Then a titania cobalt adsorbent is produced by dehydrating the molded material at least partially. As the proportion of raw material of the titania short fiber, at least 2wt% expressed in terms of TiO2 is preferably for the raw material of total titania. Also as the added quantity of titania sol, 1-50wt% expressed in terms of TiO2 is preferable for the raw material of total titania. Alkali metal and alkaline earth metal capable of dissolving into high-temp. water are not necessarily contained in the raw material to the utmost.
