Abstract
Catalysts can reduce emissions from biomass combustion systems. Efficient use in small‐scale applications is challenging due to the variations of temperature, fluid flow, and flue gas composition. An analytical procedure was defined and evaluated with three commercial catalysts to realize efficient integration. The characterization included activity measurements at three facilities: a model gas analysis device, a laboratory‐scale combustion system, and a wood log stove. The results demonstrate the possibilities of model gas analysis to define a scope of application and also the need for catalyst characterization under real operation conditions to determine the performance and stability of the final process. Temperature and gas hourly space velocity are the two main parameters influencing catalyst activity.
