本文采用内循环无梯度反应器,测定了常压下工业粒度B_(110-2)型变换催化剂宏观动力学速率。动力学测试条件如下:催化床温度330—450℃,反应气体组成(干基)CO摩尔分率0.1—0.35,CO_2摩尔分率0—0.35,汽气比0.3—1.0。用非线性最小二乘法对幂函数型宏观动力学方程进行参数估值,确定了相应的模型参数。所获得的六参数和简化四参数宏观动力学方程具有良好的等效性,其结果如下: 六参数宏观动力学方程为简化的四参数宏观动力学方程为
In this paper, the intracircular gradientless reactor was used to measure the macroscopic kinetic rate of B 110-1 catalyst under atmospheric pressure. Kinetic test conditions are as follows: catalytic bed temperature 330-450 ° C, reaction gas composition (dry basis) CO molar fraction 0.1-0.35, CO 2 molar fraction 0-0.35, steam ratio 0.3-1.0. The non-linear least square method was used to estimate the parameters of power function macro-dynamics equation, and the corresponding model parameters were determined. The obtained six parameters and the simplified four-parameter macroscopic kinetic equation have good equivalence. The results are as follows: The six-parameter macroscopic kinetic equation is a simplified four-parameter macroscopic kinetic equation
