Oligomerization of α-octene in the presence of zeolite catalysts
Abstract
Oligomerization of octene-1 in the presence of different structural types zeolites – Y, Beta, ZSM-12, ZSM-5 is investigated. It is shown that extensively porous zeolite catalysts Y, Beta, ZSM-12 exhibit a high catalytic activity at 150–200 °C. In their presence octane conversion reaches 96 %, the oligomers yield is 88–100 wt.%. Zeolite ZSM-5 has a low active at 150–180 °C and catalyzes mainly the octene-1 isomerization. If the temperature is raised up to 250 °C the main reaction products are low molecular weight oligomers of cracking products. The activity and selectivity of zeolite catalysts in the octene-1 oligomerization are due to their acidic properties and structural characteristics, as well as reaction conditions. It’s found that octene dimers with alkyl naphthenic structure is dominated among oligomers, the content of unsaturated hydrocarbons with tri-and tetrasubstituted double bonds slightly 2,2–3,2 %. Octene oligomers that synthesized in the presence of zeolite Beta, possess physicochemical properties similar to those of hydrogenated poly-α-olefin oligomerization which was carried out on complexes of AlCl3.
