Abstract

The aim of the presented study is to investigate the morphological characteristics of biomass and sewage sludge ash andraw samples by FTIR and SEM methods. Biomass and sewage sludge are adequate renewable fuels, but require furtherinvestigation focusing on the evaluation and degradation of organic and inorganic compounds in renewable fuels. In this study,biomass and sewage sludge and its ash were examined in terms of physical and chemical properties to gain an understandingof their compositional and structural characteristics through analytical approaches such as CHNS, ash composition, HHV,FTIR and SEM. The FTIR was recorded using the Bruker Alpha FT-IR Spectrometer. FTIR spectra reflects the complexand different compositions of studied fuels and the influence of the combustion process. The presented spectra evidentlydepict changes in the bond structure of the studied materials under the combustion process. Degradation of the morphologystructure is also confirmed by SEM.
