This work has been carried out to apply Fletcher Reeves, Quasi-Newton, BOX, SQP, and Mixed optimization algorithms to estimate the optimum operating parameters required for the achievement of high purities of trans-2-butene and trans-2-hexene respectively as the top and the bottom products using olefin metathesis process occurring in a reactive packed distillation column. The process was modeled and optimized with the aid of Aspen HYSYS. The model had a trans-2-pentene feed stream containing 1 ppm each of trans-2-butene and trans-2-hexene flowing at the rate of 35 mL/min into the column at a temperature of 298.15 K and a pressure of 1.125 bar. The results obtained from the optimizations of the process revealed that the constrained optimization was better than the unconstrained one for this process because, in the single objective optimizations carried out, the top and the bottom products were desired. It was discovered from the constrained optimizations carried out that Mixed algorithm was the best among the algorithms considered because it was able to give the optimum reflux ratio of 2.50, the optimum feed flow rate of 43.75 mL/min and the optimum reboiler duty of 0.28 kW that yielded trans-2-butene of mole fraction value of 1.0000 and trans-2-hexene of mole fraction of 0.9422 as the top and the bottom products, respectively
