Direct hydro-liquefaction of sawdust in petroleum ether and comprehensive bio-oil products analysis.
The effect of temperature, time, hydrogen pressure and amount of catalyst on production distribution and the bio-oil yield obtained from the direct liquefaction of sawdust in the petroleum ether (60-90°C) are investigated. The highest sawdust conversion obtained was 72.32% with a bio-oil yield of 47.69% were obtained at 370°C, 40min and 5wt.% catalyst content with the initial H2 pressure of 3.0MPa. Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) approach was utilized to analyze the non-volatile fraction. In this study, the composition of bio-oil could be analyzed in an unprecedented detail through a combination of GC-MS and FT-ICR MS techniques.
