A Dynamic Kinetic Model for Methanol to Light Olefins Reactions over a Nanohierarchical SAPO‐34 Catalyst: Catalyst Synthesis, Model Presentation, and Validation at the Bench Scale

17-Jan-2018 | Mohammad Javad Azarhoosh, Rouein Halladj, Sima Askari, International Journal of Chemical Kinetics, 2018

ABSTRACT This study includes three main parts: synthesizing the hierarchical silicoaluminophosphate (SAPO‐34) catalyst, evaluating the performance of this modified catalyst in the methanol to light olefins (MTO) process, and providing a new dynamic kinetic model for the modified catalyst. At ...

ChemKED: A Human‐ and Machine‐Readable Data Standard for Chemical Kinetics Experiments

17-Jan-2018 | Bryan W. Weber, Kyle E. Niemeyer, International Journal of Chemical Kinetics, 2018

ABSTRACT Fundamental experimental measurements of quantities such as ignition delay times, laminar flame speeds, and species profiles (among others) serve important roles in understanding fuel chemistry and validating chemical kinetic models. However, despite both the importance and abundance ...

Linking the Gold Nanoparticles Formation Kinetics with Their Morphology

11-Jan-2018 | M. Luty‐Błocho, M. Wojnicki, J. Grzonka, K. J. Kurzydłowski, K. Fitzner, International Journal of Chemical Kinetics, 2018

ABSTRACT In this paper, we show that using different concentrations of reagents, it is possible to produce gold nanoparticles with different morphology (size, shape). The color of obtained colloidal gold change from pink, violet to blue, and it corresponds to the shape change. The pink color ...

Reaction Mechanisms and Kinetics of the Melt Transesterification of Bisphenol‐A and Diphenyl Carbonate

11-Jan-2018 | Feng‐Lei Bi, Zhen‐Hao Xi, Ling Zhao, International Journal of Chemical Kinetics, 2018

ABSTRACT The catalyzed and uncatalyzed reaction mechanisms of the melt transesterification process of bisphenol‐A and diphenyl carbonate are proposed based on nucleophilic substitution at the carbonyl group of the reactants. The reaction paths and energy barriers of the melt ...

Shock‐Tube Experiments and Kinetic Modeling of CH3NHCH3 Ignition at Elevated Pressures

20-Dec-2017 | J. C. Shi, Y. L. Shang, W. Ye, R. T. Zhang, S. N. Luo, International Journal of Chemical Kinetics, 2017

ABSTRACT Ignition delay times of CH3NHCH3/O2/Ar mixtures are measured with a shock tube in the temperature range of 1040–1604 K. Different pressures (4, 8, and 18 atm) and equivalence ratios (0.5, 1, and 2) are investigated. A recently developed CH3NHCH3 kinetic model is examined, and then ...
