Experimental study on co-gasification of biomass and glycerol

Gasification of corn cob and crude glycerol and pure glycerol in the fixed-bed reactor were carried out. The effect of crude glycerol and pure glycerol on the gasification gas component trends was studied in detail. The resulted show that the crude glycerol has little influence on the trends of gas component, when the pure glycerol/raw material is larger than 20%, the trends of syn-gas and CO₂ change dramatically than that of crude glycerol. Meanwhile Aspen Plus software was used on the experimental cases, and the results show that the model can give a very good prediction for co-gasification process of biomass and glycerol.
