摘要：在小型流化床反应器中,在常压,210～250℃,流化气速0.04 m/s 的条件下,采用工业用NC-1000型氧氯化催化剂进行催化 C_2H_4燃烧副反应的宏观动力学实验。采用幂函数型动力学方程建立了C_2H_4燃烧反应动力学模型,采用改进的高斯-牛顿法回归模型参数,并进行残差分析和统计检验。结果表明,所得到的反应器出口 C_2H_4的摩尔分率的动力学模型计算值与实验数据吻合良好,可以为乙烯氧氯化流化床反应器的放大设计和模型化提供理论依据。
The kinetics of ethylene combustion over an oxy-chlorination catalyst NC-1000 were studied in a fluidized bed reactor under the conditions of 0.1 MPa, 210-250℃, fluidizing air flow 1 400 mL/min. The kinetic model of ethylene combustion was established by assuming power-law functionality. The parameters of the kinetic model were obtained by the modified Gauss-Newton method through the Matlab software, and the statistic test and residual error distribution were analyzed. Results showed that the calculated values of ethylene content agreed with the experimental values well. The kinetic model could be used to design and simulate the fluidized bed reactor.
