Experimental Study of Kinetic Parameters about Pyrolysis of Sewage Sludge

摘要

In order to meet the pyrolysis and gasification of municipal sewage sludge, Chongqing typical pyrolysis of sewage sludge kinetic parameters are studied with heat balance in the atmospheric pressure conditions. The pyrolysis kinetics of Chongqing typical municipal sewage sludge is determined. We measure the gasification activation energy of sample in an ordinary furnace is for the 39.82 kJ/mol and the preexponential factor is 19.07s~(-1). These results will be used to the actual sludge pyrolysis gasification and sludge waste mixed gasification reactor for its designing, constructing and operating.
