Porous bodies are produced which are suitable for use as supports for catalysts, including living cells, such as bacteria and which are upset resistant to acids and bases. The bodies have a significantly large average pore diameter of about 0.5 to 100 microns, (i.e. 5,000 to 1,000,000 .ANG.) and a t ...

William B Retallick: Method for making an ignition stage for a high temperature combustor. W R Grace & Co Conn, Beverly J Artale, April 18, 1995: US05406704 (40 worldwide citation)

A catalytic reactor, used as the ignition stage for a multi-stage combustor, is made by the following method. Alternate sides of a metal strip are first coated with a combustion catalyst, in such a manner that at any point on the strip, one side is coated and the other side is not coated. Then the s ...
