<p>Disclosed are a catalyst for coal combustion and a method for multiphase dynamic catalytic oxidation combustion of coal dust, wherein the catalyst consists of multiple catalyst precursor for promoting catalytic oxidation of coal particles, auxiliary components and water. The method for multiphase dynamic catalytic oxidation combustion of coal dust comprises the steps of: atomizing the catalyst continuously, then adding the catalyst into coal dust or coal slurry to obtain a multiphase dynamic catalytic oxidation system for combustible coal with the coal particles acting as catalyst carriers, metal oxide particle of nanometer size formed by high temperature flame being entrapped by suspending particles in combustion furnace so as to accelerate the catalytic combustion of coal particles. The method can improve combustion speed and burnout rate of combustible coal.</p> |
