Volatile organic compounds (VOCs) are the main factors involved in pollution control and global warming in industrialized
nations. Various treatment methods involving incineration, adsorption, etc., were employed to reduce VOCs concentration. Various
absorbents, such as activated carbon, zeolite, silica gel or alumina, and so on were broadly used to adsorb VOCs in various
industrial applications. Differential scanning calorimetry (DSC) was handled to analyze the thermal characteristics of absorbents.
Typically, a scanning electron microscope (SEM) has been used to evaluate the structure variation of absorbents under high
temperature situations. In view of pollution control and loss prevention, versatility and analysis of recycled adsorbents
are necessary and useful for various industrial applications.
