Abstract
Thin-walled honeycomb structures of activated carbon, useful for the adsorption of hydrocarbon vapors are prepared without the need for firing or sintering at elevated temperatures. The structures are prepared by forming a substantially homogeneous batch from an admixture of thermally gellable cellulose ether and/or derivative thereof such as methylcellulose, an additional organic binder such as a polyvinyl alcohol resin, and particles of activated carbon; plasticizing the batch with liquid, extruding the batch into a honeycomb shape; and drying the extruded shape at a temperature up to about 225.degree.
