A Homogeneous Gas Phase Reaction

Bellman et al. (1967) have considered the estimation of the two rate constants k and k2 in the Bodenstein-Linder model for the homogeneous gas phase reaction of NO with 02  

Equations 6.47a and 6.47b should be solved simultaneously with the state equation (Equation 6.45). The three ODEs are put into the standard form (dz/dt = p(z)) used by differential equation solvers by setting 

Integration of the above equation yields x(t) and G(t) which are used in setting up matrix A and vector b at each iteration of the Gauss-Newton method.

For a homogeneous gas-phase reaction occurring in a plug-flow reactor, explain briefly under what circumstances tlr < 1. Consider each factor affecting this ratio separately. Give an example (chemical reaction + circumstance(s)) for illustration. Assume steady-state operation and... 

In an overwhelming majority of cases, heated polymers decompose into combustible gaseous products. The latter diffuse into the oxidative environment, mix and react with oxygen. Therefore, the self-enhancing exothermal reaction responsible for the heat generation and initiation of polymer combustion is in most cases a homogeneous gas phase reaction In order to stress this particular feature of the reactions between...

The water-gas shift reaction, under the influence of an ozonizer discharge, is a homogeneous gas phase reaction. 

According to the Arrhenius equation, which was of course devised to describe a homogeneous gas-phase reaction, the rate constant k, which is the rate at unit pressure of the reactants, i.e. 

To illustrate the nature of chain reactions, we consider a classic example the formation of hydrogen bromide from molecular hydrogen and bromine in a homogeneous gas-phase reaction ... 

Thermal incineration. A process of chemical reaction which is activated by heat which occurs within a specifically designed reactor, and is often utilised for treatment of waste-gas streams that contain traces of organic matter. This can be achieved thermally, by a homogeneous gas-phase reaction, or catalyti-... 

In contrast to investigations with solid catalysts, where we can place the catalyst in a small and almost isothermal zone, we have to accept non-isothermal operation in the case of a homogeneous gas phase reaction. It is, therefore, required to determine the kinetic parameters by means of an effective reaction volume. VR efr is defined as the volume needed to reach the same conversion at a constant reference temperature T ef as under the non-isothermal conditions with an axial temperature Tx. Tref can be arbitrarily chosen, for example, the temperature at a fixed position in the middle of the tube. This definition leads to ...
