<p>PURPOSE:To obtain an adsorbent having the effect of preventing rancidity by kneading Kanto loam components and OYA-ISHI components under addition of a small amt. of water and heating the mixture thereof after molding. CONSTITUTION:Kanto loam composed of 23-30% SiO2, 25-28% Al2O3, 10- 15% Fe2O3 and 13-16% loss content and OYA-ISHI composed of 60-70% SiO2, 10-15% Al2O3, 0.5-2% Fe2O3 and 4-6% loss content are compounded at a suitable ratio. Water in the amt. smallest possible within the range below the plastic limit is added into the mixture thereof and the mixture is mixed and kneaded with a kneader. The mixture is thereafter molded to a granular body, tablet, etc. and is heated for 1-2hr at 350-600 deg.C.</p> |
