本文用0.41%(W)Pd/γ—Al_2O_3催化剂,在间歇高压釜中进行了丁炔二醇加氢合成1,4—丁二醇的动力学研究。首先进行了动力学实验,然后,对不同假设机理的速度方程进行筛选和鉴别。对复杂串平行反应网络构成的一阶非线性微分方程组用非线性最小二乘法和四阶龙格—库塔法进行速度常数的最优估值和方程组的数值求解,利用线性回归求得了各步反应的活化能。 In this paper, 0.41% (W) Pd / γ-Al 2 O 3 catalyst was used in the batch autoclave kinetics of 1,4-butanediol hydrogenation of butynediol. First, kinetic experiments were carried out, and then the velocity equations of different hypothetical mechanisms were screened and identified. The first-order nonlinear differential equations composed of complex series parallel reaction networks are solved by using the nonlinear least square method and the fourth-order Runge-Kutta method, and the numerical solution of the equations is obtained by linear regression The activation energy of each reaction.
