Liquid phase pyrolysis of wheat straw and poplar in hexadecane solvent

摘要: Abstract There is a need for replacement of fuel, especially transportation obtained from fossil resources by bio-based alternative. The thermochemical conversion feasible method to degrade and partially deoxygenate the natural resource lignocellulose get bio-oils as fuel precursors. present paper describes liquid phase pyrolysis wheat straw poplar under inert atmosphere in n-hexadecane solvent. An autoclave batch reactor system was used. influence reaction temperature, residence time, solvent/biomass ratio effect solid acid base catalysts on product distribution yields were investigated. products analyzed means CHNO elemental analysis, Solid Phase Micro Extraction-Gas Chromatograpy-Mass Spectroscopy (SPME-GC–MS), 1H 13C-Nuclear Magnetic Resonance (NMR) spectroscopies. About 40–49 wt% lignocellulosic carbon successfully transferred hexadecane. best achieved at 350 °C. main extracted alkyl alkoxy derivatives phenol furan derivatives. By comparing seven parallel experiments presence absence no or only negligible catalytic observed. heterogeneous manifested splitting primarily macromolecules. carbon/oxygen mass balances suggest that compounds have relatively high residual oxygen content.
