“…The decomposition profile of a RDF sample from thermogravimetry−differential thermogravimetry (TG−DTG) in a nitrogen atmosphere, at a constant heating rate of 10 °C/min, is reported in Figure . The curves show that the thermal decomposition is practically complete at ∼800 °C; , such decomposition occurs through a series of complex peaks that are related to the simultaneous degradation of the various fractions (paper, plastics, wood, fabrics, etc.) contained in RDF.…”

The opportunity of using refuse-derived fuel (RDF) to produce fuel gas seems to be promising, and particular attention has been focused on alternative process technologies such as pyrolysis and gasification. Within this frame, present work relates to experimental tests and obtained results of a series of experimental surveys on RDF gasification with steam, performed by means of a bench-scale rotary kiln plant at different process temperatures, using thermogravimetry (TG) and infrared spectrometry (Fourier transform infrared, FTIR) to characterize the incoming material and online gas chromatography to qualify the gaseous stream. Experimental data show that the gas yield increases with temperature and, with respect to the gas composition, the hydrogen content increases, mainly at the expense of the other gaseous compounds, which highlights the major extension of secondary cracking reactions into the gaseous fraction at higher temperature. Syngas obtained at processing temperatures of 950 °C or higher seems to be suitable for producing hydrogen for ammonia synthesis or for fuel cell applications, whereas, at lower processing temperatures, it seems usable for Fischer−Tropsch synthesis. The low organic content of solid residue does not suggest any other exploitation of the char apart from the landfilling.

“…Such an approach facilitates a RDF characterization technique applicable to co-firing of pulverized fuels. There is an urgent demand for such a technique since the conventional fuel characterization methods based on TGA [11,12] are of a limited applicability to pulverized fuel firing. Similarly, the RDF combustion characterization in fixed beds [13][14][15] although informative and useful for grate fired stockers, is practically of no help for pulverized fuel firing.…”

“…Little is known about the process of heating up a 500-1000 μm fluff "particle" suspended in an air flow and exposed to a 200 kW/m 2 heat flux. It has been established [11,12,15] that at 10-20 • C/min particle heating rates, around 80% of RDF volatiles are given off in a 250-450 • C temperature range and the other 20% is released before the particles reach 750 • C. One would expect that under rapid heating conditions prevailing in the reactor, perhaps even more volatiles would be given off. Thus, the RDF coke yield should not be larger than around 15-20%.…”
