A supercritical fluid is a substance at a temperature and pressure above its critical point. Supercritical fluid techniques have been used in biomass gasification to recover high energy gases to achieve the objectives of waste treatment and energy recovery. In this study, cinnamyl alcohol was used as a model compound to investigate the effects of lignin gasification in supercritical fluids and to find the optimal reaction conditions. Experiments were carried out in a batch reactor, 16 ml in volume. The major operating parameters include: reaction temperature (400-600 °C), reaction pressure (10-25 MPa), reactant concentration (0.1-0.25 M) and addition of 1-3 times (in weight basis) ethanol co-solvent. GC-TCD was used to analyze the gas products. The main components are H2, CO, CH4 etc. The results show that the main influential factors on gas production are temperature and ethanol co-solvent, and that vapor density and reaction pressure are less influential.
