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...

Fundamental Principles of Ayurveda Part - Iii

In this part the author explains the origination of Rasas (tastes) and their effect on Dosas (bodily humors) in various seasons. Also he throws some light on the fundamentals of Pharmacology of Ayurveda.

Theory of the Kinetics of Chemical Potentials in Heterogeneous Catalysis

Simplifying principles for chemical and enzyme reaction kinetics.

Tihonov's Theorems for systems of first-order ordinary differential equations containing small parameters in the derivatives, which form the mathematical foundation of the steady-state approximation, are restated. A general procedure for simplifying chemical and enzyme reaction kinetics, based on the difference of characteristic time scales, Is presented. Korzuhin's Theorem, which makes it poss...

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 ...
