The Optimal of Pyrolysis Process in the Rotating Cone Reactor and Pyrolysis Product Analysis

With wood shatters as raw material and quartz sand as heat medium, the process of rapid pyrolysis of biology materials with a self-made rotating cone reactor was investigated. The optimal conditions by orthogonal test indicated the pyrolysis of biology materials was pyrolysis temperature at 550 ¿, vacuum value at 0.08Mpa, rotate rate at 115r/min, diameter of materials at 30 mesh with the condition of sawdust humidity at 8.2% and material-feeding rate at 4 kg/h and heat quantity of 1200g. In the optimal experimental condition the highest oil production rate was 54.83%. The products of pyrolysis of biomass were separated by fractionation in ordinary pressure rectification. The light products was analyzed by GC-MS, the main components of which were methanol, ethanol, 1, 3-Propanediol, normal hexane, toluene, phenol cyclopentane and naphthalene.
