Ethylene to Propylene over Zeolite ZSM-5: Improved Catalyst Performance by Treatment with CuO

Abstract

In this paper, the ZSM-5 zeolite base is used to produce light olefins in the process of converting ethylene to propylene, as well as copper oxide to improve the catalyst. After loading the copper oxide by inoculation, the modified catalyst was investigated for accurate determination of the specification by XRD, SEM, BET, and FTIR analyzes. The activity of this catalyst was evaluated in the process of ethylene to propylene conversion in a constant reactor under operational conditions (temperature 400°C, pressure 1 atm, and feed flow rate of 0.5 cc min⁻¹ of pure ethylene), which also shows the results of tests of catalyst activity evaluation The modified catalyst of selectivity of ethylene and propylene will increase as the temperature rises and the maximum selectivity table at 400°C will be achieved.
