AB There are several published studies evaluating the potential of platinum and palladium-based catalysts for realflue gas purification, however, the need to reduce the mass fraction of precious metals and the effect of thisprocess is often neglected. This study aimed to assess the influence of two catalysts on the overall flue gascomposition formed during combustion in a pellet burner operated to mimic the operation of a real wood logstove. Commercial Pt–Pd-based (CAT A) and Pt-based (CAT B) catalysts with innovative sol-gel coatings and areduced amount of active substance were used. The CO, OGC and PM conversion rates of CAT A reached 87.8%,37.0% and 25.2%, while the removal efficiency of CAT B reached 85.8%, 37.8% and 18.8%, respectively. Thedecrease of organic carbon by the catalysts ranged from 28% to 49% in the case of CAT A and from 13% to 60%in the case of Cat B. The concentrations of PAHs emitted seem to indicate a less carcinogenic composition whencatalytic converters are used than without these flue gas treatment units.
