Abstract
Shaped zeolite NaY (NaY-C) with 10 wt% of glassy carbon as binder was prepared via an extrusion-carbonization procedure by using the mixture of NaY and phenol formaldehyde as precursor. Crush strength of NaY-C is 66 N·cm−1, the value of which is comparable with the shaped NaY bound by 20 wt% of alumina. The binding by glassy carbon does not disturb the framework structure, micropore size or guest cation distribution of NaY. Furthermore, the analysis based on a strategy combining Ag+ exchange and ultraviolet-visible diffuse reflectance spectroscopy indicates that as the binder, glassy carbon is more conducive to keep the framework basicity of the zeolite compared with alumina.
