Summary: Kinetic modeling has gained attention due to advanced computational tools and improved analytical techniques. Molecular kinetic modeling of catalytic naphtha reforming allows for full analysis of light petroleum fraction on a molecular level. Different kinetic models, with varying approaches and limitations, have been developed in the past decade. The review provides a systematic comparison of these models and discusses the methods for estimating kinetic parameters and determining their numerical values.

Summary: The work focuses on developing a kinetic model of the naphtha reforming process based on a previously proposed approach, taking into account differences in reaction rates of individual homologues. This model is detailed yet simple, accurately describing experimental data over a wide range of process parameters with only 39 kinetic parameters to be determined from experiments.

Summary: Process intensification in a membrane reactor is an efficient and compact way to produce hydrogen, with methane conversions approaching 90%. Compared to conventional reactors, membrane reactors can achieve higher conversion rates in a shorter time. However, nitrogen leakage through the membrane may gradually increase during testing due to pinhole formation and leakage through end seals.

Summary: This study explores non-precious metal carbide materials as alternatives to Pt for catalytic reforming, supported on non-chlorinated solid acidic zeolites. Mo2C supported on HY zeolite was found to be an active catalyst, producing aromatics at 50 wt%, RON of 96, and maintaining high reformate yields around 91 wt%.

Summary: A two-dimensional mathematical model was developed to simulate naphtha reforming in CCR reactors, and a sensitivity-based parameter subset selection method was used to identify influential parameters. By tuning the parameters, the model showed improved fit to experimental data and accurately predicted reactor temperatures, catalyst coke weight fraction, and benzene flowrate. The simulation results matched well with industrial measurements, providing valuable insights for improving the efficiency of the CCR process.

Summary: This paper investigates the performance analysis of the PdAu membrane in a packed bed reactor loaded with Ni-based catalysts in clean energy systems based on hydrogen fuels. A comparative analysis was conducted between methane steam reforming and prereformed naphtha. The study demonstrates that prereformed naphtha exhibits slightly better performance in terms of methane conversion and hydrogen yield under certain operational conditions, with lower energy consumption compared to steam methane reforming.

Summary: This paper presents the thermal coupling of the naphtha reforming process with the methanol to propylene (MTP) process. The integration of these processes allows the utilization of excess heat from the MTP process to meet the heat requirements of the naphtha reforming process, resulting in the elimination of intermediate heaters and increased propylene yield.

Summary: In experimentally monitoring the dynamics of a physical system, it is impossible to resolve all microstates or transitions between them. Theoretical modeling of partially observed systems involves considering only observed states and transitions while hiding the rest, merging microstates into a mesostate, or decimating unobserved states. The deviation from thermal equilibrium can be characterized by the entropy production rate (EPR), but only a lower bound can be inferred based on partially observed information. This study calculates partial EPR values of Markov chains driven by external forces using different notions of partial information and compares them with the EPR inferred from observed cycle affinity.

Summary: A novel method of non-thermal plasma assisted catalytic reforming of naphtha at near ambient conditions is introduced, replacing expensive hydrogen with cheaper methane. The non-thermal plasma effectively converts methane and naphtha to high-quality fuel. The produced liquid product has higher iso-paraffin content and well-controlled levels of coke deposition, olefins, and aromatics, offering a cost-effective and environmental-friendly route for naphtha reforming.

Summary: The research focuses on mathematical modeling and optimization of heavy naphtha reforming on commercial catalyst, revealing that light aromatics are produced faster and high paraffin conversion leads to an increase in octane number. The optimization process using genetic algorithm enhances the octane number of reformate from 95.62 to 96.69.

Summary: An 8-lumps kinetic model based on feedstock composition is proposed. The model is fitted using a sensitivity analysis to identify reaction pathways contributing significantly to the desired products, resulting in improved fitting. It considers commonly used lumps in the industry, making it useful. An uncertainty analysis is performed to provide a probability bandwidth for experimental data and acknowledge possible errors. The model can predict behavior of different feedstocks using a single set of kinetic parameters differentiated by a deactivation factor.
