Specific Features of Positional Isomerization of α-Olefins in the Presence of Zeolite Catalysts

The positional isomerization of the double bond in α-olefins of С₁₆–С₁₈ fraction on Y-type zeolite with the faujasite-type crystal structure in the H form was studied. An increase in the silica ratio of the catalyst from 45 to 75 leads to the formation of isomerized olefins with lower congealing points. An increase in the catalyst concentration, temperature, and process time leads to the acceleration not only of the target reaction of the double bond migration but also of the side reaction of olefin oligomerization.
