| Outline of Final Research Achievements |
Methane total decomposition, CH4→C+2H2, is confirmed to be the first step of Methane Dry Reforming (MDR) by using pulse experiments with CH4 and CO2. The intermediate which has been reported contains no hydrogen atom. Even though the formed carbon (coke) from CH4 is one of the intermediates of MDR, it can be converted to a poisonous material on the Ni surfaces. At least two kinds of coke were formed on the Ni surfaces, confirming by Temperature Programmed Oxidation experiments of coke on the catalysts. One is a reactive coke and the intermediate of MDR, and the other is a poisonous coke on the Ni surfaces.
These results clearly indicate that the stability of the MDR process can be improved without sacrificing its activity.
