Adsorption of Hydrogen Sulfide by Biochars Derived from Pyrolysis of Different Agricultural/Forestry Wastes
The characteristics and mechanisms of hydrogen sulfide(H2S) adsorption on three different boichars derived from agricultural/forestry wastes through pyrolysis at various temperatures(100℃ to 500℃) were investigated.In this study,the H2S breakthrough capacity was measured using a laboratory-characterized using pH and Fourier transform infrared spectroscopy analysis.The results obtained demonstrate that all biochars were effective in H2S sorption.The sorption capacity of the biochar for H2S removal is related to the pyrolysis temperature and pH of the surface.Certain threshold ranges of the pyrolysis temperature (from 100 to 500 ℃) and pH of the surface are present.It also concluded that the sorption capacity (for removing H2S) of rice hull-derived biochar is the largest in three biochars(camphor-derived biochar,rice hull-derived biochar,and bamboo-derived biochar).These observations will be helpful in designing biochar as engineered sorbents for the removal of H2S.
