Abstract
Carbonaceous chars capable of catalytically decomposing aqueous hydrogen peroxide at higher rates at given char densities than other known catalytic chars are provided for. This improvement is provided by an increase in the catalytic activity at a given char density of the said catalytically-active carbonaceous char. The catalytically-active carbonaceous chars are useful for, but not limited to, the catalytic conversion of H.sub.2 S, SO.sub.x, NO.sub.x, peroxides, and/or chloramines in liquid and/or gaseous media.
Claims4
A carbonaceous char having a t-3/4 time at a given Apparent Density less than or equal to:
- (15.9 cc min).times.(Apparent Density)-2.98 min, where t-3/4 time is equal to three-fourths of the elapsed time required for 0.250 gms of said carbonaceous char from ambient temperatures to decompose 0.42 mole of H.sub.2 O.sub.2 in an aqueous solution having a pH of about 7.
