The results of an experimental study of the reaction of ethylene trimerization to 1-hexene on a chromium-pyrrole catalyst are presented. The studies were carried out in the range of pressures of 18–30 bar, temperatures of 105–20°C, and catalyst concentrations of 1.165–3.500 mg/L. A mathematical model of the used semiflow reactor is also presented. A route is proposed to describe the observed reaction products. The rate constants of the elementary stages of the process are determined by solving the inverse kinetic problem. The dependences of the ethylene absorption curves on the reaction conditions, pressure, temperature and catalyst concentration, as well as the change in the degree of ethylene over the course of the experiment are analyzed.
