Formation of radicals and catalytic activity of pentasil-type zeolites in unsaturated hydrocarbon conversions
Journal of Molecular Catalysis(1986)
摘要
The formation of radicals upon adsorption of linear (C3H6), branched (isobutylene, 2,4,4-trimethylpentene-1) and cyclic (cyclopentene) olefins on pentasil-type zeolites at −78 °C and 20 °C has been studied. It is shown that on pentasil the process of C3H6 oligomerization proceeds to a certain extent, even at −78 °C. Similarities in the processes on pentasil and H-mordenite, as well as differences in the structure of radical particles due to channel shape and size, have been found. It is assumed that in the case of branched olefin adsorption on pentasil, a certain portion of the radical particles is formed on the zeolite outer surface. The process of SO2− anion radical induced formation as a result of electron transfer from olefin radicals to sorbed SO2 molecules is observed.
