[Abstract]:The high temperature pyrolysis experiment of wet sludge with moisture content of 82% (m / m) was carried out by using microwave energy with rapid heating as heat source. The effects of final pyrolysis temperature, residence time and the amount of activated carbon on the composition and content of biogas in sludge pyrolysis were investigated by single factor experiment. The optimum operating conditions for continuous operation were determined as follows: final pyrolysis temperature 900 鈩，
