Abstract
Activated carbon is prepared by treating lignite with the hot gases generated within the tail pipes of a dual-pulse-jet combustion system. Thus, two identical pulse-jets were arranged with tail pipes opposite each other and 6 in apart. Lignite was supplied at 200 No./H (sic) (ed: probably should be lb/h) to one of the tail pipes after preheating combustion was established with propane supplied at 15 psig. Activated carbon was collected at a rate of 70 lb/h. Lignite samples treated in this manner gave activated carbon containing 0.3 pct h2o and 28 pct metal- and ash-free volatile matter. Similar results were obtained when h2o-containing char was slurried in water and then introduced into the pulse jets.
