Mass action kinetics of selfreplication in flow reactors

REACTORS, KINETICS, AND CATALYSIS Spatiotemporal Patterns in Thermokinetic Models of Cross-Flow Reactors

The beha®ior of stationary and mo®ing spatially-periodic patterns in a simple crossflow reactor was simulated and analyzed for a situation in which reactant is supplied continuously along the reactor and a first-order exothermic reactor occurs. The Danck( werts boundary conditions for realistic Le and Pe ®alues. While the unbounded in) finitely long reactor is an asymptotic case used to study t...

Use of film-flow reactors for studying microbiological kinetics.

The use of a film-flow reactor for studying the kinetics of substrate removal is described. The reactor provides a means of maintaining a uniform layer of biologically active slime which is stationary while the feed solution is made to flow over the slime surface in a thin film. The study was designed to evaluate process limitations in the trickling filter process which is designed for the biol...

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 ...

Reducible Mass-Action Chemical Kinetics Systems

Preclusion of switch behavior in networks with mass-action kinetics

We study networks taken with mass-action kinetics and provide a Jacobian criterion that applies to an arbitrary network to preclude the existence of multiple positive steady states within any stoichiometric class for any choice of rate constants. We are concerned with the characterization of injective networks, that is, networks for which the species formation rate function is injective in the ...
