In this paper, the ZSM-5 zeolite base is used to produce light olefi ns 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 modifi ed catalyst was investigated for accurate determination of the specifi cation 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 fl ow rate of 0.5 cc min–1 of pure ethylene), which also shows the results of tests of catalyst activity evaluation The modifi ed catalyst of selectivity of ethylene and propylene will increase as the temperature rises and the maximum selectivity table at 400°C will be achieved.
