Gas-phase elemental mercury removal by novel carbon-based sorbents

Elemental mercury removal by the modified bio-char from medicinal residues

“…In particular micropores are considered to be the pores susceptible to blockage. This phenomenon was also observed by Tan et al for the bio-char from biomass [4]. After microwave and steam activation, the FTIR absorption peaks of S6W, S6WH5 8 and S6WN5 between 1400 and 400 cm -1 show lower intensities than their pyrolysed bio-chars without microwave activation, for example S6W< S6.…”

“…The adsorption performance of S6Z5 and S6WZ5 is low in comparison to previous research of other bio-char modified by ZnCl 2 [4]. It is attributed to the poor characteristics of the pore structure of S6Z5.…”

“…Coal combustion is considered as a dominating stationary source for atmospheric mercury emissions via human activities [4]. The elemental mercury (Hg 0 ) is receiving much attention due to its volatility, high toxicity, ability to bio-accumulate within the environment [5].…”

“…However, the high cost for AC injection is beyond the economic tolerance of combustion system. Consequently, various inexpensive carbonaceous absorbent materials were extensively studied, such as the carbonaceous absorbent materials from mulberry twig [6], bamboo [4], coconut shells [7] and coke [8]. Some kinds of inexpensive inorganic materials were also considered as promising absorbents, for example bentonite [9], natural mineral sorbents [10] and fly ash [11].…”

Microporous bamboo biochar for lithium-sulfur batteries

“…Most importantly, bamboo has a unique well-connected three-dimensional (3D) microtexture that can be carbonized into a hierarchical porous carbonaceous structure, which possesses large surface area, high conductivity, good connectivity and a highly ordered structure [18]. Therefore, bamboo biochar is currently used as an odour absorbent and has also been used to fabricate electrodes for supercapacitors and LIBs [18,[23][24][25][26].…”
