Latest Patents

Hisashi O Kono's latest patents focus on innovative processes for producing alumina granules. The first patent describes a method for producing alumina granules in a fluidized bed. This process involves pretreating alumina powder by mixing it with cold water at temperatures below room temperature, specifically below about 20°C. This results in pretreated alumina with a pore volume saturated with water and a gel structure surface area. The agglomeration of this pretreated alumina in a fluidized bed leads to the formation of granules, particularly suited for producing activated alumina in macroporous granules. The second patent also details a similar process for fluidized bed granulation of rehydratable alumina, emphasizing the importance of temperature control and the use of a cold hopper for cooling alumina powder prior to pretreatment.
