Selective conversion of light olefins to high octane-number gasoline on novel Fe-silicate catalysts

Conversion of light olefins to gasoline was investigated for various metallosilicates having the pentasil pore-opening structure. The metallosilicate was prepared by replacing the Al ingredient of the H-ZSM-5 with various metal salt at the stage of gel formation. Among various metallosilicates H–Fe-silicate was most effective and stable for the selective formation of high octane-number gasoline. The causes of this high catalytic performance was attributed to its proper acid strength and low diffusion resistance.
