Abstract
1. The conversions of propene and isobutene on the pentasil NTsVK were studied in a wide range of conversions of the olefins and the values of the initial rate of formation of oligomers of the original alkenes and the rate of accumulation of aromatic hydrocarbons in the products of catalysis were calculated. It was suggested that the values of these rates be used for the quantitative estimation of the activity of zeolites in side reactions. 2. The selectivity of the conversion of propene, isobutene, as well as 1-hexene and 1-octene, on the pentasil NTsVK to aliphatic or aromatic C6-C10 hydrocarbons can be regulated by varying the rate of delivery of the original olefin. 3. The general scheme of conversions of low-molecular-weight olefins on zeolites of the pentasil type to aromatic hydrocarbons through an intermediate step of oligomerization, the products of which can then undergo dehydrocyclization, cracking, and other reactions, proposed earlier, was refined.
