Study on High-Temperature Catalytic Combustion : (2nd Report, Mass Transfer Effect on Catalytic Combustion)

Abstract

Catalytic Combustion is considered to be the best combustion method to achieve lower NOχ levels. And many devices having catalytic combustion have been developed and are under development. For the application under high pressure condition like a gas turbine combustor, a catalyst performance and a catalyst temperature under a high pressure condition must be expected on the data under atmospheric combustion test. The heat and mass transfer effects on a catalytic reaction were studied theoretically, and the results showed good agreement with the experimental results. It is clarified that the mass transfer is dominant in catalytic reaction, the conversion rate is decreased with pressure, and therefore, the catalyst length used under high pressure should be designed longer than that under atmospheric pressure condition.
