H–D tracer experiments during n-octane aromatization on Cr2O3/La2O3/ZrO2 catalysts allow conclusions to be drawn on the reaction mechanism. The rate-determining step is the dissociative adsorption of the paraffin molecule. The following dehydrogena

The hydrogen chemisorption on Pt/Al2O3 was investigated by temperature programmed desorption. The activation energy of desorption strongly depends on the hydrogen surface coverage. The chemisorption process is shown to be activated. High temperature

The conversion of methanol to hydrocarbons was investigated on alumina-supported H 4 [SiW 12 O 40 ] catalysts. Depending on the concentration of the heteropoly compound, two different types of [SiW 12 O 40 ] 4− anions exist on the surface of the ca
