Compressed adsorbent filter cake |
摘要 |
A compressed adsorbent filter cake for removing caffeine from liquids. The filter cake is composed of a compressed matrix of fibrous material; and adsorbent particulate material integrated within the compressed matrix of fibrous material, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The compressed matrix of fibrous material may a compressed wet-laid fibrous mat. The adsorbent material may be selected from clay minerals and zeolites. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.
