The Dust Attrition of Granular Carbon Adsorbents: Test Procedure and Typical Test Results

Abstract

A new test procedure, using the vibrating equipment previously described in Memorandum Report 4179 has been developed and applied to a variety of granular carbon adsorbents. The results are reported as a dust attrition coefficient D.A., having the units of mgs/minute at a given vibrational acceleration. It is possible to estimate the initial dust content, mg/gram of samples, from that formed during the test. Among closely-sieved fractions of a carbon sample the larger particles are subjected to greater attrition than smaller particles during the test. Passage of a granular carbon through a regenerating kiln does not influence the D.A. of the particles, but the dust fraction increases slightly. The attrition behavior of adsorbent mixtures is discussed. The test procedure has been subjected to round-robin testing by the D-28 Subcommittee of ASTM.
