Abstract
An acid-impregnated activated carbon matrix is formed from a carbonaceous material by the addition of a mineral acid, and may be used to chemisorb ammonia from a gas stream. The ammonia reacts with the acid to form a fertilizer salt. The spent matrix may be used as a fertilizer, or the fertilizer salt may be elutriated from the matrix.
