Abstract
A highly adsorbent, temperature-resistant monolithic activated carbon article is obtained by forming an aqueous emulsion of a polymeric binder, combining the resulting aqueous emulsion with wet, activated carbon particles to produce a slip mixture, forming the obtained slip mixture into a shaped article, and thereafter curing the shaped article.
Claims15
A microporous, monolithic carbonaceous article exhibiting substantially no loss in compressive strength upon heating to 200° C. and consisting essentially of activated carbon and a polymeric binder;
- said polymeric binder being present in an amount up to 13 percent, based on the weight of the article, and said article having a butane activity in excess of 8 grams per deciliter.
A microporous, monolithic carbonaceous structure consisting essentially of active carbon and a water-dispersible high-temperature binder, said structure having a butane activity in excess of about 8 grams per deciliter, said high-temperature binder being thermally stable up to 275° C. and being present in an amount up to 13 percent, based on the weight of the composition.
A microporous, monolithic carbonaceous article exhibiting substantially no loss in compressive strength upon heating to 200° C. and consisting essentially of activated carbon having a surface area in excess of about 1100 m2/g and a polymeric binder;
- said polymeric binder being present in an amount up to 13 percent, based on the weight of the article, and said article having a formation efficiency in excess of about 75 percent.
