A sample holder has been designed to achieve the uniform absorbed-dose distribution in electron-beam (EB) irradiated ZSM-5 catalyst. Simulated results, without considering the holder’s rotation, demonstrated that the holder configuration should be a cylinder hollow, while its dimensions are recommended to be 10–14 cm in outer radius, 7–8 mm in thickness, and 50–54 mm in height. The holder’s rotational contribution to the simulated results was estimated to be less than 1%. An actual holder was fabricated based on this design. Steamed ZSM-5 catalyst (∼32 g) was used to verify the catalytic cracking performance of the sample under EB irradiation. The irradiating experiment was conducted using the fabricated holder, with the 10 MeV EB and a fluence of 8 × 10&sup(14) e.cm&sup(−2) (257 kJ). The catalytic cracking experiments indicated that most catalytic productions strongly increased with low heavy cycle oil (HCO) yield when irradiated ZSM-5 was used instead of steamed non-irradiated sample. Excellent increases were simultaneously found, for the first time, for propylene (∼24%) and gasoline (∼15%) productions. Irradiated sample also exhibited superior stability compared to non-irradiated one.
