چکیده انگلیسی
Methane decomposition was conducted by using K2CO3/carbon hybrids as the catalysts, and hydrogen-rich gas (with hydrogen content of about 87%) and fibrous carbons can be simultaneously obtained together with high and stable methane conversion (up to about 90% at 850 °C). Effects of K2CO3 on methane conversion, hydrogen content and fibrous carbons were investigated by changing the reaction temperature and space velocity. The results indicate that K2CO3 can greatly promote methane activation and conversion, taking responsibility for the continuous formation of CO and a trace of CO2. The oxygen transfer from K2CO3 probably provides convenience for the formation and growth of fibrous carbons.
