Abstract: | This paper briefly reviews the most important aspects of catalyst testing in packed-bed catalytic laboratory reactors to properly assess the intrinsic chemical kinetics. Next it discusses approaches to assess the kinetics of fast reactions or those accompanied with strong heat effects that cannot be performed in a packed-bed reactor configuration free from transport limitations. As an example the partial oxidation of methane is presented in a steady-state fixed bed reactor as well as in a TAP (temporal analysis of products) reactor. The continuing increase in computational power leads to more sophisticated reaction and reactor models due to the increasing use of computational chemistry and computational fluid dynamics in reaction engineering. |
