Abstract:
On the basis of a model of the reaction of components, taking the change in the contact surface into account, we analyze how the transport of one component to the surface of the other affects the ignition temperature. We have found that chemical gas transport converts the reaction process from ignition at the center of the space to ignition from the reactor wall. In the reactor are two regions, delimited by a curve of equilibrium concentrations of the carrier compound transporting the other component. The carrier compound forms and builds up in one region and in the other region separates out on the surface of the other. The fact that the reactor is closed and that diffusion occurs from one region to the other make it possible to produce superequilibrium concentrations of the carrier compounds in the region of deposition.
