Abstract:
The last years, acid hydrolysis (AH) process has widely been studied for the production of ethanol and bio-chemicals some of which (levulinic acid or furans) can be used as diesel miscible biofuel. In an EU project (DIBANET) we investigated the development of an AH process for levulinic acid (LA) production from agricultural residues. The objective of the work presented in this paper is to investigate upgrading options for solid acid hydrolysis residues (AHRs) towards production of bio-oil through thermal and catalytic pyrolysis. In this study Miscanthus AHRs produced from different hydrolysis and pretreatment conditions were used. All AHRs were fully characterized for their cellulose, hemicellulose and lignin contents and for elemental analysis. The AHRs were tested in a small scale pyrolyzer using silica sand and a commercial ZSM-5 for thermal and catalytic pyrolysis respectively with the focus on the yield and quality of the produced bio-oil. Correlating the severity of the AH treatment with the pyrolysis yields and oil quality allowed for a mapping of AH conditions so that the best process for downstream AHR upgrading can be selected.
