ABSTRACT:
The instant invention is directed to an activated carbon impregnated with 0.1 to 10 percent, by weight, of an amine compound, which is solid and sublimes at 40.degree. C. or above, and having a moisture content after impregnation of 5.0 percent or less, by weight.
The instant invention is also directed to a process for impregnating carbon comprising allowing an amine compound, which is solid and sublimes at the temperature at which said amine is applied, to sublime in the presence of an activated carbon.
The instant invention is also directed to the use of the impregnated carbon in removing toxic gases from a gas stream comprising passing the gas stream through the impregnated carbon.
