Method of reactivating spent activated coal
Abstract
Abstract SPENT ACTIVATED COAL IS REACTIVATED BY CONFINING A BODY OF IT IN A FLUIDIZED-BED REACTOR AND SUBJECTING IT TO FLUIDIZATION UNDER CONTINUOUS ADMISSION OF FLUE GASES OF A PREDETERMINED TEMPERATURE AND CONTAINING WATER VAPOR OR CARBON DIOXIDE. TREATED COAL IS CONTINUOUSLY REMOVED FROM THE FLUIDIZED BED AND THE TEMPERATURE OF THE LATTER IN THE REGION FROM WHICH THE TREATED COAL IS REMOVED IS MAINTAINED AT A CONSTANT TEMPERATURE LEVEL BELOW THE TEMPERATURE OF THE FLUE GASES, THE REGULATION OF THE CONSTANT TEMPERATURE LEVEL BEING ACCOMPLISHED BY CONTROLLING THE ADMISSION OF ADDITIONAL SPENT COAL INTO THE REACTOR AS AN INVERSELY PROPORTIONAL OF FLUCTUATIONS OF THE TEMPERATURE LEVEL.
