US Patent:

20050110178, May 26, 2005
Filed:

Nov 25, 2003
Appl. No.:

10/722882
Inventors:

S. Harris - Wilmington DE, US
Joel Shertok - Newark DE, US
John LeSieur - Newark DE, US
International Classification:

C01B031/02
B29C067/04
B29C067/20
US Classification:

264029100, 264029600, 264041000, 264043000
Abstract:

The present invention relates to an effective and rapid method and apparatus for sintering carbon filter blocks having a polymeric binder. The method employs direct contact heat transfer by gas molecule to powder particle, as opposed to conduction heat transfer from an external heating source, using commercially available sintered porous metal sheets and cylinders to form the mold and confine the powder, while allowing heated gas to pass uniformly through the mixture.
