Abstract

Abstract

The dehydration of denitration catalyst carrier titanium dioxide is a key control step in the preparation process. By measuring the thermal analysis curves of denitration catalyst carrier titanium dioxide at different heating rates, the dehydration kinetics and reaction mechanism of denitration catalyst carrier titanium dioxide under different atmospheres were studied. The results indicate that the dehydration behavior of titanium dioxide as the carrier of denitrification catalyst is closely related to the calcination atmosphere. The dehydration rate is different in oxygen-containing and oxygen-free atmosphere. Dehydration starts faster in oxygen-containing atmosphere, and then slowly dehydrates until the reaction ends, while dehydration completes slowly in oxygen-free atmosphere. Kinetic calculations were carried out by using the methods of modularless function and modularized function. The results show that the dehydration behavior of titanium dioxide, the support of denitration catalyst, conforms to the Avrami Erofeev equation in oxygen-containing atmosphere, and conforms to the power function rule in oxygen-free atmosphere. The dehydration process is affected by the formation and growth of crystal nuclei.
