ABSTRACT:
Untreated coal is activated with steam at temperatures of 600.degree. to 950.degree. C. in a vibrating fluid bed, which is directly heated. The untreated coal is pre-dried by counter-current passage of the waste gases from the reaction either during feeding of the untreated coal or in the first part of the vibrating fluid bed trough. During the activation, secondary air can be passed in through a sparge pipe which is arranged parallel to the vibrating fluid bed trough. It is possible to carry out the heating exclusively with the supply of secondary air.
