Aim To develop a low temperature catalyst for the Sabatier carbon dioxide reduction of atmospheric regeneration to reduce the onset temperature of Sabatier reaction. Methods The design and development of low temperature catalysts were carried out from the aspects of catalyst active components, carrier selection, catalyst preparation methods and conditions, and the catalyst performance testing device was established to study the performance of low temperature catalysts. Results A low-temperature catalyst for Sabatier reaction with ruthenium as active component and active r Al 2 O 3 as carrier was prepared. The reaction start-up temperature was reduced to 110 ℃ and the start-up time was 8 min. At a temperature of 200 ~ 300 ℃ When the lean components passed the conversion rate were higher than 95%; product water more pure, colorless and transparent, was neutral. Conclusion The performance of the Sabatier reaction at low temperature catalyst has achieved the design goal and has the value of further research.
