Then, the deposition of the catalytic elements inside the micro-channels by a spray-coating technique was carried out.
Catalytic elements were developed that preheat the incoming lean fuel/air mixture up to temperature of ca. 1100 K at the required high (20 30 m/s) operating velocities and inlet temperatures (670 690 K).
Herewith, all key catalytic elements needed to transform propane directly to acrylonitrile are contained, strategically arranged and within bonding distance of each other, at the active center of the M1 phase.
The catalytic elements serve to pretreat the fuel in order to enhance performance in terms of emissions (<3 ppmv NOx and <10 ppmv CO @ 15% O2 at 50 100% load, for natural gas fuel), part-load stability (reducing the lean blow-out temperature by over 100 °C) and thermoacoustic phenomena (pulsations ≪ 0.3% of pressure).
By correlating the superficial oxidation state of the catalytic elements measured by X-ray photoelectron spectroscopy with the information provided by the DBA probe reaction, it was possible to progress in the description of the atomic scale architecture of the oxidation sites at work.
This catalytic oxidation, induced at low temperature by alkali and alkaline-earth elements (Na, K, Ca), is a crucial issue for aeronautical applications of C/C composite materials because of the presence of these catalytic elements in de-icing solutions used in airports.
