Estimation of Kinetic Parameters and Simulation of Methylacetylene and Propadiene Liquid-Phase Selective Hydrogenation Reactor Considering the Catalyst Deactivation

Abstract: This paper presents a kinetic study of methylacetylene (MA) and propadiene (PD) liquid-phase selective hydrogenation considering catalyst deactivation. For this purpose, more than 20 000 plant operational data points were collected from two different fixed-bed reactors in an olefin plant during a 14-month run-step. Four different kinetic models were used parametrically in a dynamic reactor simulation. The genetic algorithm (GA) technique was used to estimate the kinetic constant by minimization of the mean rel… Show more

“…Note that the discussion of the first three types mostly ignored the effect of transport phenomena on reaction kinetics modeling. To incorporate the transport effect into kinetics modeling, one can collect plant data from largescale reactors 302 but the economic cost is usually very high. Alternatively, one can also combine ML/DL with the CFD or the classic simplified reactor model.…”
