Résumé : Solid Recovered Fuel Wood (SRFW) is an ideal wood substitute in downdraft fixed bed air gasification processes: SRFW syngas quality and process performances are equivalent to wood syngas on both pilot and industrial scales. Syngas Low Heating Value (LHV) ranges from 4.7 to 5.0 MJ/Nm3 for SRFW, and from 4.3 to 4.8 MJ/Nm3 for wood. Differences have been found at pilot scale in H2S and NH3 contents: For H2S, SRFW syngas reaches 3 to 10 ppmv while wood syngas ranges from 2 to 5 ppmv. For NH3, SRFW syngas reaches 1,000 to 3,000 ppmv while wood syngas ranges from 370 to 500 ppmv. This could be explained by higher sulfur and nitrogen contents in SRFW compared to wood. At industrial scale SRFW syngas shows higher H2S content than at pilot scale, probably due to a higher char conversion caused by higher temperature.
