Abstract: A method is provided for the removal of metalloid and non-metal hydrides from gas or liquid media. The improvement is provided by the use of a high-temperature carbonaceous char derived from a carbonaceous feedstock which has been exposed to nitrogen-containing compounds at temperatures above 700.degree. C. In the preferred embodiment of the method, the high-temperature carbonaceous char is prepared by carbonizing and oxidizing a bituminous coal at temperatures less than 700.degree. C followed by exposure to urea, ammonia, or nitrogen-containing compound as the temperature is raised to above 700.degree. C.

Abstract: A method is provided for evaluating the catalytic activity of carbonaceous chars via the decomposition of hydrogen peroxide in contact with such materials. In this method the rise in temperature occasioned by the decomposition of hydrogen peroxide under essentially adiabatic conditions is monitored as a function of time. By use of this method, carbonaceous chars having high catalytic activities may be rapidly and conveniently identified.

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.
