微藻微波催化裂解研究及动力学分析
, PP. 315-320
Keywords: 微藻,微波裂解,催化剂,动力学
Abstract:
？采用微波设备对微藻粉末进行热解实验,分别研究了活性炭、h3po4、naoh、mgcl2、mgo对微藻微波裂解的影响,以及不同功率(200、600、900w)下微藻裂解失重的变化。结果表明,对于所研究的五种无机添加剂,均能够显著增加固体产物产率,明显减少气体产物产率,添加剂对液体产率的影响不是很显著,但h3po4和mgcl2使液体产率提高,naoh使液体产率降低。微藻的微波裂解过程大致可以分成脱水、干燥、快速裂解和缓慢裂解四个阶段。采用flynn-wall-ozawa法对微藻微波裂解进行动力学分析,计算出相应的微藻快速裂解阶段的活化能,活化能基本上随反应的进行而增大。
