Optimization of Bamboo Pyrolysis Process to Prepare Bio-oil by Response Surface Methodology
摘要
Abstract
In order to increase the yield of bio-oil from bamboo biomass by fast pyrolysis process in a fluidized bed, the response surface methodology (RSM) was applied to optimize the process conditions, and the pyrolysis temperatures (450-550^), vapor retention times (1.5-2.5 s), and particle sizes of bamboo (0.18-0.22 mm) were selected as independent variables. The central composite design (CCD) was used to build the model and to analyze the effects of the above variables on the yield of the bio-oil, and the results show that the three variables have obvious effects on the bio-oil yield. However, the interactions between the three variables have no significant influence. According to the established model, the optimal conditions within the experimental ranges for bio-oil yield are: pyrolysis temperature is 519.0℃, vapor retention time is 2.1 s, and the particle size is 0.18 mm, and the theoretical yield is 58.17% at the above optimal conditions. With these optimal conditions, the average actual value of the bamboo bio-oil yield in three replicated experiments is 57.85%, which is not significantly different from the predicted value of 58.17% by the model. The RSM is simple and convenient, and the results would provide a scientific reference for the preparation of bio-oil from bamboo biomass by fast pyrolysis in fluidized beds.关键词
