Process for the production of a low density activated alumina formed product. |
摘要 |
<p>An improved process for the production of a low density formed product of an activated alumina having a large macro-pore volume and an excellent abrasion resistance, which comprises mixing the starting solid material which is an alumina powder capable of being re-hydrated or a mixture of the alumina and an other solid material with water, the starting solid material having an average particle size of 1 micron to 35 micron and a quarter deviation of particle size distribution of not more than about 1.5, forming the mixture of the solid material and water into various shapes, re-hydrating the formed product by maintaining it under a wet atmosphere or in water, and calcining the resulting re-hydrated product.</p> |
