ABSTRACT
To promote engineering application of municipal sludge pyrolysis technology, pilot-scale sludge pyrolysis device systems integrated were set up to study the effectiveness of sewage sludge pyrolysis. With the application of various operating conditions, the optimal conditions and products were obtained. And comparing the operational effectiveness of pilot-scale experiment with the bench experiment, the optimal operating conditions and product characteristics coincide with those of the bench experiment. Through energy balance analysis, energy produced from pyrolysis oil and gas together or just from sewage-char is almost sufficient to supply the energy required for sewage sludge pyrolysis.
