Abstract

The role of Brönsted acid (and basic) sites of molecular sieves is compared for four different acid-base catalyzed reactions, i.e., n-alkane conversion, isomenzation of xylene, reaction of methanol to dimethylether and alkylation of toluene. The coverage at the catalytically active sites and the surface chemistry during the reaction is followed by in situ i.r. spectroscopy using CSTR with i.r. light transparent windows. This allows to directly compare the surface chemistry with the catalytic activities and selectivities. Conventional isotope labelling and steady state isotope transient experiments are used to further support the mechanistic models of the acid-base catalyzed reactions outlined above.
