Systematic study of the performance of a reverse flow reactor for the treatment of lean hydrocarbon emissions

Abstract

BACKGROUND: Reverse flow reactors are widely used for the treatment of gaseous emissions containing different hydrocarbons. However, most of the reported studies are focused on the combustion of a given hydrocarbon over a given catalyst. Consequently, any conclusions are difficult to extrapolate to other systems due to the wide range of variation of the chemical properties in these systems (reactivity, concentrations, combustion enthalpy, etc.).

Performance of silicon‐carbide foams as supports for Pd‐based methane combustion catalysts

“…Due to its simplicity and the very small effect of methane concentration on the reaction kinetics, the pseudo‐first‐order kinetic model can be useful for practical applications (i.e. reactor design) 36. Statistically, the best model is Mars–van Krevelen, which presents the higher adjusted square regression coefficient ($\hbox{R}_{\rm {adj}}^{2}$ ) and the lower sum of square errors (SSE), but the difference with the other two models is rather small.…”

The role of reaction kinetics and mass transfer in the selective catalytic reduction of NO with NH3 in monolithic reactors

“…The resulting set of ordinary differential and algebraic equations is solved using the MATLAB function ode15s, especially suited for stiff problems. The whole problem is formulated in a code written in MATLAB …”

“…The whole problem is formulated in a code written in MATLAB. 32 The fitting of model parameters has been done using the least-square technique, based on minimization of the sum of the square residuals. The problem has been solved in MATLAB using the lsqcurvefit function and a trust-region-reflective algorithm.…”

Reverse flow reactors as sustainable devices for performing exothermic reactions: Applications and engineering aspects

“…Methane oxidation in catalytic RFR (or RCO) has been studied experimentally by many authors. One of the reasons of this interest is because methane is one of the hydrocarbons most refractory towards oxidation, thus requiring a higher ignition temperature [40]. This means that a successful operation of the reactor with methane will be easily extended to most VOCs without the need of long individual studies.…”
