The microkinetic model simulates a continuous stirred-tank reactor (CSTR) with no concentration or temperature gradients. The reaction conditions used in the model are configured to be close to the experimental setup. Ethylene oligomerization is modeled at a temperature of 523 K and a total pressure of 1 atm. The reactor has a dimension of 1 cm × 1cm × 1 cm. The feed stream contains 20% of ethylene and 80% inert gas, and the feed volumetric flow rate is 1 cm 3 s -1 .
