Method A low temperature catalyst was designed from the considerations of the active composition, the choice of the carrier, the production method and condition of the catalyst. Then the performance of the newly developed low temperature catalyst was tested. Result A new low temperature catalyst for the Sabatier reaction using Ru as the active composition and using r Al 2O 3 as the carrier was developed. The start up temperature was lower than 110℃ and the start up time was 8 min; The conversion efficiency of the lean component (H 2 or CO 2) was over 95 percent when the temperature of the reactor was from 200℃ to 300℃; The reaction product water was nearly colorless, transparent and neutral. Conclusion The test results showed that the goals of the design are achieved and it is worthwhile to make further studies on the low temperature catalyst.
