Abstract:
In a process for producing activated carbon adsorbant structures using resin binders to bond the activated charcoal particles, the improvement comprising:(a) preparing a substantially homogeneous particulate mixture by combining 5 to 30 weight percent polyolefin resin powder having an average particle size between 5 and 125 microns and 70 to 95 weight percent particulate activated carbon; (b) introducing the particulate mixture prepared in step (a) into a microwave transparent container; (c) exposing the container containing the particulate mixture to microwave radiation to increase the temperature of the activated carbon 3 to 30Â° C. above the crystalline melting point of the polyolefin resin; (d) compacting the particulate mixture to increase contact between the particles; and; (e) lowering the temperature of the particulate mixture below the melting point of the polyolefin while maintaining point bond formation conditions.
