Characteristics of Carbonization Residue with Mixture of Woody Waste and Sewage Sludge

Biomasses such as woody waste and sewage sludge can be converted to renewable energy source by using carbonization process. Carbonization process is carried out to obtain energy characteristics of carbonization residue from the mixture of woody waste and sewage sludge. The effects of temperature, time, and sewage sludge content on carbonization process are estimated by energy characteristics of the residue such as heating, yield, and fuel ratio. From the results of energy characteristics of residue, the optimum content of sewage sludge in carbonization process can be decided by 30%. At the optimum content of sewage sludge in carbonization process, the carbonization residue of mixture of woody waste and sewage sludge can be deserved to use one of renewable energy sources from the results of fuel ratio and total heating value.
