just had a thaught peroxide decomposes rapidly at high temperature (well i hope so because the rest of my thaught is based on that)
so if you placed say a piece of carbon with "the right shape" TM in the combustion chamber such that the peroxide was sprayed onto it and a portion of it was in the hot exhaust section. the heat from the exhaust would soak through the carbon and decompose the peroxide generating more hot gas to continue the cycle. i only say carbon because off the top of my head it has the highest heat tollerance and there wouldnt be too much wear on the "heater" I spose is the word for it. To start up some form of catalist may be plated onto the surface or it could be electrically warmed on the pad or some such. thaughts? ----- Original Message ----- From: "Randall Clague" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, October 17, 2002 9:32 AM Subject: Re: [ERPS] Catalysts (again) > On Tue, 15 Oct 2002 22:27:43 -0400, "Sean Patrick Daly" > <[EMAIL PROTECTED]> wrote: > > >In my never ending search for a longer lasting/highly reactive catalyst > >pack, I've noticed that the folks over at Boeing claim to have developed a > >catalyst bed that was tested to 10,285 seconds with 98% H2O2.
