Temperature Programmed Adsorption (TPA) of Various Hydrocarbons on Adsorbers of Honeycomb Type

摘要

TPA characteristics of two adsorbers of honeycomb type for various hydrocarbons were evaluated. In this study, methyl alcohol, acetone, acetaldehyde, 224 trimethylpentane, n-octane and toluene were chosen as the hydrocarbons of cold start. The effect of the hydrocarbon components and oxygen concentration on TPA behavior was studied. According to the precious metal loading and the presence of O_2, the adsorption and desorption amount were decreased, while the conversion efficiency of hydrocarbons was increased. In case of hydrocarbons with oxygen, the thermal decomposition appeared to be in the order of methanol, acetaldehyde and acetone.
