Abstract: Abstract The Fe–Cu13x molecular sieve catalyst was synthesized by ion exchange method. The product is having various applications, mainly within the food industry, agriculture industry, and also within the pharmaceutical industry. The denitration characteristics and anti-toxicity of Fe–Cu13x catalyst were investigated. Combined with a variety of characterization methods, it was found that the denitration performance of the catalyst was superior, and the denitration rate was more than 99%. In the subsequent anti toxicity test, Fe Cu catalyst showed good sulfur resistance. The NOx conversion rate of the catalyst remained above 90% after 3 h of sulphur resistance, while the no and removal efficiency decreased to 60% after 4 h of sulfur resistance. After the sulfur supply was stopped, the conversion rate did not increase and showed a gradual deactivation state. When the temperature increased to 400 °C, the catalyst could still maintain more than 95% NOx removal rate.
