摘要
In a variety of reactions in the chemical industry egg-shell catalysts with a thin active layer are applied, which are often crushed for laboratory testing. The destruction of the shell can be avoided by a special reactor design. The presented Advanced TEMKIN reactor is a further development of the reactor system for testing egg-shell catalysts in laboratory scale published by Temkin et al. in 1969. It is suitable for kinetic studies as well as for the detailed research of deactivation processes, as is shown on the example of the selective hydrogenation of acetylene.
