Acetaldehyde combustion using platinum catalyst

摘要

Catalytic Converters are extensively used for reduction of the pollutants released from various sources to the atmosphere. These converters become effective in minimising the pollutant concentration only after they achieve their operating temperature. During this cold start period hydrocarbons are released untreated to the atmosphere. This paper deals with the oxidation of hydrocarbon acetaldehyde, a VOC during the cold start period. Mathematical modeling is a good way of analysing the converter behaviour without performing very expensive and time consuming experiments. A one-dimensional computer model that takes into account the mass and the heat transfer between the gas phase and the catalyst is considered. The equations form a set of ordinary and partial differential equations, which are non-linear and coupled. These equations are solved using Runga kutta and Backward Implicit scheme.
