Characteristics and kinetic studies on pyrolysis of blooming-forming cyanobacteria
摘要
Abstract
Pyrolysis characteristics of blooming-forming cyanobacteria at different heating rates (5,10,15,20 ℃/min) was studied by thermogravimetric analysis (TGA).Activation energy of the pyrolysis reaction was calculated by iso-conversional method and the mechanism function was determined by master-plot method.The results showed that pyrolysis of blooming-forming cyanobacteria mainly occurred in 170 ～ 530 ℃.With the increasing of heating rate,the maximum weight loss rate increased and the peak temperature move to the high-temperature zone progressively.The activation energy almost kept a constant when the conversion ratio of 0.2 to 0.7,which indicated a single reaction mode could be used to described for the pyrolysis process.The R2 of fitting curve between experimental curves and theoretical curves was 1,when the reaction order was 5.3.The calculated pre-exponential factor was 7.24×1021 s-1 and the pyrolysis reaction of blooming-forming cyanobacteria could be expressed by da/dt=3.62×10 exp(-169.71/RT)·(1-α)5.3.关键词
