In the dilute sulfuric acid/toluene system with extremely low water/solid ratio (short in ELW system), hemicellulose from corncob was converted into furfural with high yields in a short time. In order to establish an economic and effective biorefinery system, the use of ELW residues needed to study. Taking the residues from furfural plant (short in plant residue) as contrast, the potential of ELW residue and plant residue as solid fuels for pyrolysis (conventional pyrolysis and rapid pyrolysis) and high value utilization were comprehensively compared. It was found that both the ELW residue and plant residue had a certain degree of carbonization. In addition, the high calorific value and conventional pyrolysis products of ELW residue were similar to plant residue; while levoglucosan yields from ELW residue by rapid pyrolysis were much higher than corncob and plant residue.
