Such a method should be versatile enough to simulate a wide range of conditions whicha re applicable for catalysts designed to oxidize hydrocarbons and carbon monoxide, or to reduce nitric oxide, as the case may be. For this purpose we have modified a pulse-flame combustor, based on a design by Meguerian. The output of this simulator very closely resembles engine exhaust withr espect to composition, space velocity,a nd contaminants. The durability of a monolithic or pelleted catalyst can be evaluated by long term exposure to thes imulated exhaust and by periodic measurement of the catalyst activity as a function of temperature. The apparatus and the range of conditions that can bea achieved are described in detail. Poisoning of a Pt catalyst by fuels containing low concentrations of lead was studied with this exhaust simulator and compared with results obtained in engine dynamometer tests.
