MAKING DISCRETE SOLID PARTICLES OF POLYMERIC MATERIAL

摘要

A process is provided for producing discrete solid beads of polymeric material e.g. phenolic resin having a mesoporous structure, which process may produce resin beads on an industrial scale without aggregates of resin building up speedily and interrupting production. There is also provided apparatus for forming discrete solid beads of polymeric material. A method is provided for carbonizing and activating carbonaceous material, which comprises supplying the material to an externally fired rotary kiln for carbonizing and activating temperatures, the kiln having a downward slope torn progress the material as it rotates, the kiln having an atmosphere substantially free of oxygen provided by a counter-current of steam or carbon dioxide, and annular weirs being provided at intervals along the kiln to control progress of the material There may further be provided an externally fired rotary kiln for carbonizing and activating carbonaceous material having a hollow rotary body that has a downward slope towards a discharge end thereof, and which is provided at intervals along its length with annular weirs for controlling progress of the carbonaceous material.
