It was found that hydrogen and carbon black were produced at the mole ratio of 2:1, and carbon black of around 30 nm was produced, which is comparable to classical furnace black. In a study of catalyst effect, Pt-loaded catalysts showed higher activities than a Pd catalyst for the conversion of methane by plasma-catalytic process. The productivity of carbon black increased with platinum loading up to 3 wt.%. (C) 2004 Elsevier B.V. All rights reserved.
