Abstract: The development of environmentally friendly catalysts has become a top priority for acetylene hydrochlorination. However, difficulties remain in systematic studies on the applicability of kinetic models for the industrialization of Cu-based catalysts. Therefore, a strategy involving reactor modeling, parameter estimation, and model testing is developed to evaluate the predictive ability of kinetic models. In order to search for reliable and widely applicable reaction kinetic models for Cu-based catalysts, a case study is conducted. Multiple possible kinetic models derived from the power law, adsorption mechanism, and reaction path are sifted through collecting and testing activity data from tens of Cu-based catalysts. Different optimum applicable ranges of these kinetic models are presented. According to the comparative analysis on their applications in various industrial scenarios, this research suggests that kinetic models derived from reaction path exhibits the best extrapolation ability and has the greatest potential for application in the scale-up design of reactors.
