建立了动力学模型来描述稀土金属交换 Y 型 (REY) 沸石催化裂解废塑料中的重油生产汽油。我们之前报道过反应条件对产物分布的影响。根据这些结果，提出了反应路径并建立了一组微分方程。通过实验数据的非线性最小二乘回归确定动力学参数。发现这些参数与所用催化剂的强酸位点的数量成正比。发现产品分布的计算值与实验数据非常吻合
A kinetic model was developed to represent the catalytic cracking of heavy oil from waste plastics by rare-earth metal exchanged Y-type (REY) zeolite to produce gasoline. The influences of reaction conditions on the product distributions were previously reported by us. On the basis of these results, a reaction pathway was proposed and a set of differential equations was developed. The kinetic parameters were determined by nonlinear least-squares regression of the experimental data. These parameters were found to be proportional to the amount of strong acid sites of the used catalysts. The calculated values of the product distribution were found to be in good agreement with the experimental data
