131. Air Purification in an Adiabatic Reverse-Flow Reactor by Catalytic Combustion

Air Purification in a Reverse-Flow Reactor: Model Simulations

The behavior of a reverse-flow reactor was studied for the purification of polluted air by catalytic combustion. A heterogeneous one-dimensional model was extended with a heat balance for the reactor wall. An overall heat transport term is included to account for the small heat losses in radial direction. The calculations are compared to experimental data without using fit parameters. The agree...

repository copy of Coal mine ventilation air methane combustion in a catalytic reverse flow reactor : Influence of emission humidity

7 The role of the humidity content on the performance of catalytic reverse flow reactors (RFR) for the 8 abatement of methane emissions from coal mines is studied in this manuscript. It has been 9 demonstrated that this technique is very useful for the abatement, and even upgrading, of these 10 emissions. However, the effect of humidity on the reactor performance has not been addresses yet, 11 ...

Adiabatic Reverse Combustion in a Packed Bed

Downward propagation of a combustion front in a packed bed of wood particles, with air supply from below, is examined theoretically and experimentally. Using a single-step reaction, with a kinetic model of char oxidation as the dominant mechanism, and assuming local thermal equilibrium, but allowing a local chemical nonequilibrium between the solid and gas phases, the front speed u F, the adiab...

Multivariable model predictive control of a catalytic reverse flow reactor

This paper is devoted to the multiple input multiple output (MIMO) model predictive control (MPC) of a catalytic reverse flow reactor (RFR). The RFR aims to reduce, by catalytic reaction, the amount of volatile organic compounds (VOCs) released in the atmosphere. The peculiarity of this process is that the gas flow inside the reactor is periodically reversed in order to trap the heat released d...
