| 제목 | Dynamic modeling of catalytic autothermal reformer of diesel in solid oxide fuel cell - auxiliary power unit system |
| 초록 | A fuel reforming process in solid oxide fuel cell based auxiliary power unit system offers many advantages in applications in terms of supplying hydrogen rich gas stream into the fuel cell unit. One practical reforming process is autothermal reforming (ATR), essentially a combination of partial oxidation and steam reforming process. As a part of the overall system, autothermal reformer is necessarily to be modeled for optimized design and operation condition and most importantly, improved efficiency. The developed dynamic model implemented with the kinetics found in the previous study well describes the transient behavior of the catalytic monolith reactor. The corresponding experimental data is used for validation of the model based on gPROMS. The simulation is varied with a few characteristics (i.e., input flowrate, dimension of the reactor) in order to realize the effects of these operating conditions to the output temperature and composition. Based on the sensitivity studies, an optimal operating condition of the ATR in auxiliary power unit system is determined. |
