Evans, A. G.

Cooperative efforts have led to the development of several promising new impregnation formulations containing HMTA (hexamethylenetetramine) and iodine salts. The new formulations have been applied to base carbons derived from coconut shells, coal, petroleum, and wood. The newly developed impregnated carbons perform as well as, or better than, commerical charcoals containing triethylenediamine (TEDA). The most successful combinations consist of coal carbon impregnated to 2% HMTA, 2% iodine (as KI and KIO/sub 3/), KOH, and NaH/sub 2/PO/sub 4/ . H/sub 2/O. Performance data are reported for the complete series of tests performed on the charcoals. Tests include methyl iodide retention tests, high-temperature I/sub 2/ penetration tests, ignition temperature tests, measurement of the carbon pH (water extracts), and confirmation of impregnation levels by neutron activation analysis. Specific impregnation techniques are also discussed.
