Nickel-Carbon Composite Nanomaterial Synthesis via Plasma Catalytic Pyrolysis

摘要: The experiment was conducted using the PLASGAS plasma reactor, which has an internal volume of 200 liters and utilizes the Hybrid Water Stabilized Plasma torch. The characteristics of the Hybrid Water/Gas DC Arc Plasma Torch and the PLASGAS reactor are detailed by Hrabovský et al.[1] and Fathi et al.[2], respectively. Previously, this system has been employed for the pyrolysis of methane [3] and natural gas [4]. In this study, however, we investigate methane pyrolysis by adding Nickel Oxide powder as a catalyst.This experiment introduced a 100 SLM methane feed into the reactor, with plasma power set at 110 kW. The resulting gas composition was 86.5 vol% hydrogen and 12.1 vol% carbon monoxide, with only 1.2 vol% methane remaining unconverted and 0.1 vol% acetylene produced. In addition to hydrogen production, a solid carbon-nickel (core-shell) structure nanocomposite material was synthesized …
