Реферат:
Considerable attention has been paid to catalysis on zeolites, both in applied and fundamental studies. However, the elucidation of reaction mechanisms in such systems is complicated by the fact that the course of reaction can be determined not only by the active sites of the zeolite but also by the influence of the surrounding micropores (effect of pore confinement). As a result, it is often difficult to determine what actually gives rise to the kinetic parameters (activity, selectivity, activation energies) that are measured in a real catalytic experiment. In the present work, this problem is investigated by using a combination of two complementary in situ methods—namely, Fourier transform infrared spectroscopy (FTIR) and gas chromatography (GC) kinetic studies—to obtain a complete picture of molecular transformations for a model reaction in a zeolite microporous environment. From the FTIR kinetic studies, it is possible to follow directly the transformation of a molecule on the active center; in the GC studies, it is possible to observe the products that desorb from the active sites and leave the zeolite pores. In the study described in the chapter, the dehydration of butanol on H-ZSM-5 was selected for the investigation as a suitable model reaction because (1) the molecular dimensions of butanol are rather similar to the dimensions of the microporous channels in ZSM-5, giving rise to a situation where a considerable influence of the surrounding channels on the course of reaction might be expected, and (2) butanol has 4 different isomers, enabling variation in reactant geometry and reactivity.
