Activated carbon adsorbent with increased heat capacity and the production thereof

Claim 1

A process for enhancing the heat capacity of activated carbon adsorbent pellets formed by adding a binder to partially activated carbon powder, pelletizing the powder-binder mixture, and further activating the resulting pellets at elevated temperature comprising mixing said partially activated carbon in its powder form with volume based higher heat capacity dense alumina in the form of corundum in a particle size range suitable for mixing therewith, prior to pelletization of the powder-binder mixture, the amount of said dense alumina in the form of corundum present in the mixture being from about 1% to about 25% by volume based on the total volume of said mixture of said dense alumina and activated carbon powder, said binder being present in an amount within the range of from about 0.5 to about 4.0% by weight of said binder based on the total weight of said activated carbon--dense alumina in the form of corundum--binder mixture, whereby the addition of said dense alumina in the form of corundum to the activated carbon powder facilitates the desired enhancing of the heat capacity of the resulting activated carbon adsorbent material.
