Energy and exergy analysis of co-gasification of crude glycerol and animal fat mixtures

This work presents an energy and exergy analysis of co-gasification tests of crude glycerol and animal fat mixtures, in order to obtain first and second law efficiencies, the last ones representing a novelty in the field of gasification technology. Mixtures with 5% (w/w) of dry animal fat, 57% (w/w) of dry treated crude glycerol and 38% (w/w) of water were studied in a fixed bed down flow gasification reactor at 800 degrees C and 900 degrees C. The increase of gasification temperature seems not to affect the energy and exergy yields of the overall process.
