Modeling of reforming reactor was conducted by expressing the heat and mass balances under non-steady state conditions. Kinetic and thermodynamic parameters were taken from the literature. Simulation in steady-state and transient state was carried out by using Matlab software. It was determined that some compounds exhibit net increase in concentration such as low molecular weight paraffins, while other compounds undergo net disappearance. Depending on the compound the time to attain the pseudo-steady-state is different. Perturbation of feed temperature was also modeled. The time to achieve the quasi steady-state was obtained and when compared it with the start-up condition time they were almost similar under the conditions used in this study. (C) 2014 Elsevier Inc.
