摘要: Abstract The influence of Fe, Co, Ni and Ca nitrate additives on the gasification commercial graphite electrodes with hydrogen was characterized by TPR measurements. order catalytic activity has been established as > Co Fe. low temperature peaks at 300–400 °C appear preoxidized surfaces only. Ca, inactive alone, shows strong promotion hydrogen, especially in case catalyst. highest synergistic effect found for Co/Ca/CO2 activated sample. Samples CO2 show higher reactivity methane formation than samples O2.
