Abstract
An activated carbon body having flow-through channels and method of making the body. The method involves combining and shaping channel-forming material and optionally fugitive pore-forming material and non-fugitive support material, and a crosslinkable resin into a green body and curing the resin. The temperature at which the channel-forming material begins to distort is greater than the curing temperature of the resin. The resin is carbonized and at the same time the channel-forming material is vaporized out to form a carbon body having flow through channels in the configuration of the fugitive material. The carbon body is then activated. Among other shapes the channels can be straight, curved or crisscrossed.
Claims17
A method for making an activated adsorbent carbon body having flow-through channels, said method consisting essentially of:
- a) providing a crosslinkable resin;
- b) providing continuous fugitive material wherein the temperature at which said continuous fugitive material begins to distort is greater than the curing temperature of the resin;
- c) combining and shaping the continuous fugitive material and resin into a green body, and curing the resin;
- d) carbonizing the resin and at the same time vaporizing the continuous fugitive material to form a carbon body having flow through channels in the configuration of the fugitive material;
- and
- e) heating the carbon body to activate the carbon and produce said activated carbon body.
