摘　　要：生物质能源是近年来逐渐兴起的可再生能源,有望替代传统化石能源,成为未来人类利用的主要能源之一,受到越来越广泛的关注。以稻壳为原料,通过微波快速裂解技术制备可再生的生物油,为充分利用废弃物制备可再生能源提供新的途径。通过Box-Behnken中心组合试验设计,优化出制备生物油产率最高的工艺参数:裂解温度为627.81℃、微波功率为1.9 kW、吸收剂添加量为3.27%、裂解时间为5.52 min,生物质油得率的预测值为35.87%。Bio-energy has drawn much interest as a renewable energy in recent years,and is expected to replace traditional fossil fuels.It may becomes one of the main resources of energy in the future and draws more wide attention.Rice hull was used as the raw material in this study,and renewable bio-oil was obtained by using microwave fast pyrolysis technology.A new way of using the waste to prepared renewable energy was provide.Box-Behnken central composite experimental design was used to optimize the process parameters with the highest bio-oil yield obtained under these conditions： pyrolysis temperature was 627.81 ℃,microwave power was 1.9 kW,addition of absorbent was 3.27%,reaction time was 5.52 min.The predictive value reached 35.87%.
