Carbons were prepared from carbonized polyvinylidene chloride (850ยฐC) by activation with CO, at 830ยฐC to 85 per cent burn-off. Characterization of these carbons was made from gas phase adsorption data using nitrogen (77ยฐK) and carbon dioxide (195" and 273ยฐK) as adsorbates in conjunction with the Dub
The objective of the investigation described was to establish the basic nature of the underlying processes involved in the catalytic activation of coke by the addition of sodium carbonate to coal before carbonization. Cokes were made in laboratory carbonizations of a series of coals, representative

In the course of systematic studies covering various aspects of the reactivity of alkali metal amalgams we report here about first results on the behaviour of selected sodium amalgams in liquid ammonia. Starting from the most alkali metal rich amalgam Na,Hg one can show that a stepwise extraction of
