Fast moving bed pyrolysis
WebConventional Fast Pyrolysis Conclusions New and improved conventional fast pyrolysis reactors have been developed in recent years. We have described the utilization of close-coupled multiple fluidized reactors. Selective condensation methods for various bio-oil fractions have been developed. WebFast pyrolysis typically results in a product distribution of 75 wt.% bio-oil, 12 wt.% char and 13 wt.% gases (5). The bio-oil generated has the following properties: low pH, low heating value, poor, volatility, high viscosity and high oxygen content. The quality of the bio-oil can be enhanced by using a catalyst during the pyrolysis (6).
