Thermal Pre-treatment of Sewage Sludge in Fluidized Bed for Enhancing its Solid Fuel Properties |
초록 |
In the present work, fluidization of sewage sludge, a non-lignocellulosic biomass, was studied using a bench scale fluidized bed. The influence of torrefaction temperature ranging from 200 – 350 °C and residence time of 0 – 50 minutes on the physical and chemical properties of sewage sludge was investigated. The properties of torrefied product were analyzed on the basis of degree of torrefaction, ultimate and proximate analysis, gas analysis and chemical exergy. The degree of torrefaction and chemical exergy showed positive influence on increasing the torrefaction temperature. The effect of torrefaction temperature and residence time was studied on elemental variation of sewage sludge which exhibited a decrease of H/C and O/C ratios. The product gas emitted during torrefaction was analyzed to study the pathway of hydrocarbons and oxygen containing compounds. Torrefaction using fluidized bed improved the overall physiochemical properties of sewage sludge. |
