,The adsorption-pressure equation for carbon dioxide with the 

 lignite at 20°C. was found to be: (see Fig. 4). 



x = 42-7p-4« 



The Adsorption of Hydrogen 



With the hgnite at 20°C., very Httle hydrogen is adsorbed. The 

 following results were obtained but they do not conform to those 

 obtained for other gases:
