The adsorbent can adsorb and desorb small molecules such as H, N2.CH, C0. C02.02 etc. under operating conditions, but it is difficult to desorb liquid, sulphide and many large molecules such as high hydrocarbons (Cs+), tar, naphthalene, benzene etc. after adsorption. These substances are equivalent to 'toxic substances' for the adsorbent, once the adsorbent is adsorbed the adsorbent will not be able to desorb and regenerate in time, or cannot be completely desorbed, the adsorbent will lose its a...
