Adsorbents from Methane Fermentation Sludge

摘要: The product gas (the biogas) of the CH4 fermentation mainly consists CH{4} and CO{2}. In fermentation, a large amount sludge is yielded valuable utilisation desired. Therefore, we prepared adsorbate from char at 673-1273 K. was used for recovery biogas humidity control. We investigated influence carbonisation temperature on pore structure adsorption property. size distribution 673-773 K very sharp range between 0.40 0.43 nm. adsorbed much smaller than that CO{2} especially, 1173 small. rate 20 times faster 773 it found this suitable biogas. isotherm water vapour char, specific surface area commercial activated carbon (commercial AC), but larger AC high humidity, increased rapidly.
