详细技术说明

By coating porous media, such as a high temperature ceramic comprising alumina and/or silicon carbide, with perovskite catalystsΓÇömaterials with a crystal structure ABO3ΓÇöthe temperature within the media can be 1) high enough to support heat and power applications while also 2) low enough for the catalysts to remain active and keep materials in the combustion chamber from degrading as they would at uncontrolled high temperatures.

*Abstract

UCF researchers have developed a simple, but significant, improvement for porous media, a critical component of internal combustion engines and the applications that rely on them, with a catalyst enhancement to improve temperature conditions for more efficient fuel-burning. The new catalyst-coated porous media enables combustion of lean mixturesΓÇöfuels with a high percentage of air and a low percentage of fuelΓÇöwhich allows for fuel flexibility. This makes more energy per dollar possible since applications can burn low-calorific fuels that generate fewer harmful emissions. Simple, efficient porous media minimizes environmental contamination and conserves energy resources without sacrificing performance. This porous burner technology is critical when generating power from thermoelectric devices, small-scale heating, and combustion of low-calorific value landfill-seepage gases.
