Hi everyone
I want to analyze the HZSM-5 by BET but I don`t have any information about how to degass it in which condition ( temperature and duration)
According to the literature, the zeolite sample was degassed under a high vacuum at 300 C for 8 h. Moreover, you can follow another condition that samples were degassed at 200 °С in N2 flow for 16 h to remove the moisture and other adsorbates.
