Abstract
A powder comprises a mixture of up to 40 weight percent activated cokes and inert materials. In the mixture, at least one of the inert material components is matched in terms of its grain size distribution to the grain size distribution of the activated coke component so that in a gas medium at rest, the speed of vertical descent of the coarse grain of the inert material component is substantially equal to the speed of vertical descent of the coarse grain of the activated coke component.
