摘要：
A method for producing an adsorbent, having the steps of combining a first sludge and a second material to form a mixture, thermally drying the mixture, and pyrolizing the mixture using at least four temperature zones wherein each temperature zone is set between about 600° C. and 1,100° C. The first sludge is a municipal sludge or an industrial sludge, and the second material is a compost material or one of municipal sludge or industrial sludge differing from the first sludge. The compost material is at least one of tobacco waste, waste paper and wood char, or a combination thereof. Further, the drying can happen in two stages. Each stage can include two separate temperatures.
