ABSTRACT:
A new method of forming agglomerates of fine powdered solids comprises dispersing the powder in a chemically inert carrier liquid that also contains a dissolved binder precursor polymer with cyclic dicarboxylic acid anhydride groups on the polymer chain. The dispersion is shaped and then brought into contact with a second carrier liquid that contains polyamines. The polyamines react with the anhydride groups on the other polymer to form an insoluble binder polymer that hardens the shaped dispersion. The hardened shape can then be separated from the liquids and/or further reacted if desired to produce amide bonds in the final agglomerates. The method is useful for forming mechanically and thermally stable agglomerates of such materials as activated carbon, metals dispersed on catalyst carriers, etc.
