201 Production of pyrolysis oil from sewage sludge

Abstract

From the viewpoint of global warming prevention, it is expected that sewage sludge will be used effectively as low-calorific energy resources. Then, experiments of the pyrolysis of dry sewage sludge using the fluidized-bed reactor were carried out. It was found that reaction temperature and the amount of supply steam have an influence over the pyrolysis oil yield and composition. From these results, it suggests that oil production process from sewage sludge with Internally Circulating Fluidized-bed Gasifier (ICFG) can be formed.
