| Abstract: | The skeletal isomerization of C4-C7 1-olefins was studied on ferrierite (FER) and ZSM-5 (MFI) zeolites to elucidate the effect of the molecular distribution
in zeolite pores on the selectivity foriso-olefin formation. Regardless of the difference in molecular length of 1-olefins, the FER zeolite showed high selectivity
foriso-olefins, while the selectivity became slightly low at the skeletal isomerization of long olefin molecules. The drastic decrease
in the selectivity of MFI zeolites by increasing the conversion is concurrently observed in the skeletal isomerization of
C4-C7 1-olefins. The high selectivity of FER zeolites is explained by their sparse distributions of olefin molecules in pores,
which induces a high preference for monomolecular skeletal isomerization. |
