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...
thermal decomposition of two coal samples obtained from top seam sibi (tss) and sore range quetta (srq) coal fields in their raw and acid washed forms were carried out in an open type tubular pyrolyzer coupled to a gas chromatograph with fid. elemental analyses were carried out with scanning electron microscope-energy dispersive x-rays (sem-edx) analyzer. effect of inherent mineral contents on ...
Adsorption of m-aminophenol and p-nitrophenol from aqueous solution on activated carbon synthesized on the base of industrial by product (coal tar pitch) and furfural was investigated. The adsorption capacity of the activated carbon and its oxidized modification is related to the surface area and composition of the prepared materials, as well as to the nature of the adsorbents. Despite the mode...
