Catalytic combustion with periodic flow reversal

Analysis and Control of Catalytic Flow Reversal Reactor

In this paper, we study the closed loop control of Catalytic Flow Reversal Reactors (CFRR) used for oxidation of methane. We present different techniques like logic-based control, scheduling and model predictive control. Comparison of the relative performances of these methods in maximizing the conversion while maintaining the CFRR in the desired region of operation is made. We also analyze the...

Catalytic Combustion of Methane

Catalytic combustion is an environmentally benign technology which has recently reached the stage of commercialization. Palladium is the catalyst of choice when considering gas turbines fuelled with natural gas because of its superior activity for methane oxidation. Several fundamental issues are still open and their understanding would result in an improvement of the technology. Hence, the wor...

Catalytic Combustion of Syngas

The catalytic combustion of syngas/air mixtures over Pt has been investigated numerically in a channel-flow configuration using 2D steady and transient computer codes with detailed hetero-/homogeneous chemistry, transport, and heat transfer mechanisms in the solid. Simulations were carried out for syngas compositions with varying H2 and CO contents, pressures of 1 to 15 bar, and linear velociti...

Model Predictive Control of a Catalytic Flow Reversal Reactor with Heat Extraction

This paper presents the formulation of a controller for a Catalytic Flow Reversal Reactor (CFRR) with heat extraction. The controller is based on the Model Predictive Control (MPC) concept. The MPC scheme uses a model that assumes plug flow and neglects radial gradients in the reactor but accounts for the two phases within the reactor. The prediction of the future output behavior from the model...
