Abstract
Organically complexed nanocatalyst compositions are applied to or mixed with a carbon-containing fuel (e.g., tobacco, coal, briquetted charcoal, biomass, or a liquid hydrocarbon like fuel oils or gasoline) in order to enhance combustion properties of the fuel. Nanocatalyst compositions can be applied to or mixed with a solid fuel substrate in order to reduce the amount of CO, hydrocarbons and soot produced by the fuel during combustion. In addition, coal can be treated with inventive nanocatalyst compositions to reduce the amount of NOx produced during combustion (e.g., by removing coal nitrogen in a low oxygen pre-combustion zone of a low NOx burner). The nanocatalyst compositions include nanocatalyst particles made using a dispersing agent. They can be formed as a stable suspension to facilitate storage, transportation and application of the catalyst nanoparticles to a fuel substrate.
