Active carbon molded body with fibrous binder
The granted patent US12059665B2 introduces an innovative active carbon molded body characterized by its unique composition and production method. The molded body consists of a plurality of active carbon granules, each formed from an aggregation of active carbon particles bound together by a fibrous binder. Notably, the patent specifies that the molded body contains no additional molding-purpose binder apart from the fibrous binder, which is present in a concentration ranging from 6 wt % to 20 wt %. The density of the molded body is defined to be between 0.4 g/cc and 0.5 g/cc, with a more specific range of 0.46 g/cc to 0.5 g/cc mentioned in one of the claims.
Additionally, the patent outlines a method for producing this active carbon molded body. The process involves obtaining the active carbon granules by aggregating active carbon particles with the fibrous binder, followed by further aggregation of these granules using the same binder. The final step in the production method includes molding the aggregated granules through the simultaneous application of heat and pressure. The claims also highlight that the fibrous binder may include an acrylic material, which could contribute to the structural integrity and performance of the molded body. This patent presents a significant advancement in the field of active carbon materials, potentially enhancing their applications in various industries.
