ABSTRACT:
An improved process for the production in high yield of activated carbon particles of high activity comprises rapid removal of volatile material from the area of carbonaceous particles during the carbonization step by individually venting each hearth of a multiple hearth furnace. The carbonaceous particles which are subjected to the carbonization step are prepared from mixtures of carbonaceous material and petroleum acid sludge.
