改性TiO2光催化剂用于铝酸钠溶液脱硫的研究
Study on the Desulfuration of Sodium Aluminate Solution Using a Modified TiO2 Photochemical Catalyst
摘要
Abstract
Using high-sulfur bauxite in the Bayer production process can cause harmful effects due to the sulfur entering the production system.This paper discusses the addition of a modified TiO2 catalyst to eliminate the adverse effects of sulfur on alumina production.Results show:S2-conversion rate is 100％,S2O32-conversion rate is 77.86％when the active component load rate of catalyst Mn-TiO2 is 1％,carrier gas(O3-bearing)ventilation is 50 mL/min,the reaction time is 60 min.关键词
