Abstract

RDF (Refuse Derived Fuel) and
lignite from Afsin-Elbistan region were subjected to carbonization to produce their chars. For this purpose, these samples were
heated from ambient to temperatures of 400, 500, 600, 700,
800, 900^oC by a heating rate of 10^oC/min in a tube
furnace under nitrogen flow. Then, the chars were characterized in terms of the
calorific values and the functional groups were investigated using FTIR
(Fourier Transform Infrared Spectroscopy) technique. Also, some fuel blends
where the chars of RDF and lignite are blended in different ratios were
prepared. Effects of the charring process on the fuel properties of RDF and
lignite were interpreted.
