Abstract: 
C2–C4 alkenes conversion over high-silica zeolite catalyst modified with 2 mas % of Zn has been investigated at the laboratory plant of flow type within temperatures ranges of 723–773 K and volumetric flow rates 1000–30000 h-1. It has been shown that a propylene high conversion and high yield of liquid catalizate containing lower arenes are achieved at space velocities of 20000 h-1.
