NUMERICAL INVESTIGATIONS OF CHEMICAL KINETICS FOR METHANE CATALYSIS AND PYROLYSIS

Numerical Investigations of Chemical Kinetics for Methane Catalysis and Pyrolysis

In the framework of the active and regenerative cooling of hypersonic and space structures, a kinetic mechanism should be proposed to investigate numerically the fuel pyrolysis and the coke formation with a possible surface effect (catalytic reactions). This chemical mechanism should be suitable for Computational Fluid Dynamics approach (limited number of species and reaction). For this purpose...

Kinetics of biomass catalytic pyrolysis.

The Coats-Redfern method was used to analyze the kinetic characteristics of biomass catalytic pyrolysis, indicating that it can be described by multi-step reactions, rather than as a simple first-order reaction. Friedman model-free calculations were used to describe the starting reaction types and the corresponding initial kinetic parameters. Finally, nonlinear regression of biomass catalytic p...

Reactors, Kinetics, and Catalysis

( ) CO oxidation on Pt 100 was in®estigated at reactant pressures of 8 Pa using ellipsomicroscopy for surface imaging to monitor spatiotemporal pattern formation on the catalyst surface and mass spectroscopy to monitor the integral reaction rate. Three distinct temperature regions showing nonlinear phenomena were found. The first region, at 540 ] 615 K, is characterized by macroscopic, regular ...
