Effect of acidity and diffusibility on coke deactivation over nano-sized HZSM-5 zeolites
Four series of nano-sized HZSM-5 zeolite catalysts were prepared with different steaming and HNO3 leaching processes. These samples were studied by XRD, NH3-TPD, FT-IR, n-hexane and cyclohexane adsorption, and fi...
