Carbon dioxide reforming of methane on a cobalt catalyst subjected to plasma–chemical treatment
The effect plasma–chemical treatments of 5 wt % Co/SiO2 catalyst have on its activity in the carbonic acid conversion of methane in the interval of 700 to 900°C is studied. A plasma glow discharge in oxygen and argon was used along with high-frequency plasma in hydrogen for preliminary treatment of...
