摘要

A fluidized bed was applied to the photocatalytic reduction of high-level nitrogen oxides. The photocatalyst (TiO_2) with primary particle diameter of 21nm was used as the bed material. Smooth fluidization of ultrafine particles was attained through formation of agglomerates. The effects of various factors on the NOx reduction were examined. It was found that the reduced NOx concentration increased with increases in the light intensity, the gas velocity, the amount of photocatalyst, and the inlet concentration.
