Abstract

Abstract

The specific titanium dioxide, a catalyst carrier for denitration, was prepared from metatitanic acid in the process of sulfuric acid titanium dioxide production, via ammonia neutralization, active element complexing, calcination and pulverization. The crystal structure and morphology of the powders were characterized by means of particle size distribution, XRD and SEM. The results show that the as-prepared titanium dioxide for denitration catalyst support is anatase type with uniform particle size distribution and good particle morphology. With the increase of calcination temperature, the diffraction peaks of the as-prepared denitration catalyst support TiO₂ SA90, SA100 and SA200 are much lower than those of pure anatase titanium dioxide sample BA01-01. The crystal size is in the range of 100-200 nm, and the activity is good.
