ABSTRACT:
A method and composition are described for the decomposition of sodium-mercury amalgam in a reactor containing solid packing particles to form hydrogen, sodium hydroxide, and denuded mercury. The novel packing particles are comprised of a heterogeneous solid mixture of a matrix of a thermally stable polymer having embedded therein discrete particles of a surface active composition. Suitable thermally stable polymers include polyphenylene sulfide and suitable surface active compositions include carbon, iron, nickel, cobalt, vanadium, and molybdenum. The proportion of the polymer in the packing generally ranges from about 20 to about 80 percent by volume. Preferably, the matrix is prepared in porous form which may also be coated with a surface active metal.
