Evaluation of the use of ceramic foams as catalyst supports for reverse-flow combustors

Experimental demonstration and modeling of an adsorption-enhanced reverse flow reactor for the catalytic combustion of coal mine ventilation air methane

“…The experimental device has been described in detail in previous works [25,26,[28][29][30][31]. Here, only the basic information is provided.…”

“…For example, in the selective catalytic reduction of nitrogen oxides with ammonia, forced unsteady state reactors are used to increase the amount of ammonia adsorbed in the catalyst, and hence increase reaction rate [17,23,24]. Another example, in the field of volatile organic compounds abatement, is the use of forced unsteady state reactors (reverse flow reactors, simulated moving bed reactors or reactor networks) to concentrate the organic compound prior to the oxidation [16,18,[25][26][27][28][29][30][31]. The capture of the CO 2 generated by the reaction is also possible [15].…”

A new method for controlling the ignition state of a regenerative combustor using a heat storage device

“…In addition, very low switching times reduce considerably the life of the switching valves. The selected switching time value, 120 s, is a good balance between these two situations [32,34]. The model, being one-dimensional, does not require feed flow rate as design parameter.…”

“…The description of the experimental procedure and validation has been published in previous works; different types of solid bed materials have been tested: random particles [35], honeycomb monoliths [32] and ceramic foams [34].…”

“…The other physical and transport properties appearing in the equations are calculated using correlations from the literature; for further details refer to previous works in this field [32,[34][35].…”
