英文摘要： Linear α-olefins (in range of C4 ~ C24) is an important chemical raw materials developed rapidly in recent decades, which is used widely in the fields of petrochemicals, synthetic materials and fine chemical. Aiming at the key scientific issues on the difficulty for adjusting pore structure and acidity of the molecular sieve modified catalyst and the low activity and selectivity of olefin oligomerization, the project will combine the Microporous-Mesoporous composite containing tunable pore structure and acidity distribution characteristics with the iron-containing compound. By investigating synergies effect on pore structure and acidity distribution of the composite, connection behavior of the iron-containing compound with multi-level pore structures, as well as polymerization and diffusion behaviors of olefins inside the different nano-pores, it will establish the relationship between the tunnel-acidic synergies effect, microstructures of the iron-containing compound, and performances of α-olefin synthesis reaction. All of these studies provide theoretical support of industrial development and application for the α-olefin synthesis catalyst with high activity and selectivity as well as excellent stability.
