Kinetic model for selective trimerization of ethylene to hexene-1 on chromium-pyrrole catalyst
https://doi.org/10.18412/1816-0387-2024-4-65-77
Abstract
This works presents a kinetic model for trimerization of ethylene to hexene-1 on a chromium-pyrrole catalyst. Within the framework of the kinetic model, a scheme of elementary reactions is suggested for description of the reactions principles. The rate constants of the process stages, components orders of reactions and activation energies reflecting the temperature dependence of reaction stages have been determined. The model results are in good agreement with experimental data in the range of pressures 18-30 bar, temperatures 105-120℃ and catalyst concentrations 1,165-3,500 mg/l.
