Preparation of Activated Carbons from Chinese Coal and Hydrolysis Lignin

Preparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust

In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...

Adsorption of 1,1-Dimethylhydrazine by Hydrolysis Lignin

Many modern launch vehicles use unsymmetrical dimethylhydrazine (UDMH) as liquid fuel in the space program. UDMH is highly toxic and poses a serious threat to the environment and to humans. One of the most effective methods of UDMH neutralization in case of fuel spills is adsorption. This paper is the first to suggest using hydrolysis lignin as rocket fuel adsorbent. The research was based ...

Activated carbons prepared from thermally and chemically treated petroleum and coal tar pitches

Petroleum and coal tar pitches have been treated thermally at 4008C and 4708C, extracted with toluene and subsequently activated with CO at 9008C. With one exception, the development of the micropore widths and volumes in the resulting 2 carbons follows the trend observed for carbons based essentially on precursors of vegetable origin. On the other hand, petroleum pitch treated at 4008C leads t...
