Clean, solid carbon. Made from methane, not from oil.
A carbon production route based on plasma pyrolysis of methane: high-purity carbon suitable for modern applications, with no combustion and no direct CO₂.
Carbon black, without the furnace.
HyPlasma® introduces an alternative route for producing solid carbon materials. Through plasma pyrolysis of methane or enriched gas streams, the patented three-phase plasma torch converts CH₄ into hydrogen and solid carbon without direct CO₂ emissions.
The process yields a family of clean, multi-form carbon materials whose properties can be precisely adjusted to the requirements of different markets, from general-purpose applications to high-performance grades.
Process flexibility, consistency and a combustion-free approach make it a sustainable and competitive alternative to conventional carbon black production.

What the analyses say.
High purity
Elemental analysis by EDS spectroscopy confirmed a near-exclusive carbon composition, with no detectable impurities or residual metals — the result of a combustion-free process in a controlled environment, without oxidants or metal catalysts.
Typical amorphous structure
X-ray diffraction shows the broad, low-intensity peaks typical of amorphous carbon black, alongside other carbon structures identified by XRD and high-resolution TEM.
Homogeneous spherical morphology
Transmission electron microscopy shows homogeneous, spherical primary particles — the morphology expected of commercial carbon black.
Variable specific surface areas
BET measurements indicate specific surface areas from 69 to 126 m²/g depending on synthesis conditions, which allows targeting different ASTM grades:
- High surface area (> 100 m²/g): grades such as N110 or N220, for tyre treads and high-strength materials.
- Moderate surface area (~70 m²/g): grades such as N360 or N550, for liners, soles and engineering plastics.
Process flexibility
By adjusting operating parameters on the same experimental platform, a wide range of commercial carbon blacks and other carbon structures can be produced.
Results already obtained: carbon black corresponding to several ASTM grades (N1XX to N5XX), amorphous carbon structures identified by XRD and high-resolution TEM, and — under specific plasma and humidity conditions — graphene oxide structures.
One process, a spectrum of advanced carbons.
Beyond conventional carbon black, HyPlasma® opens the way to a broader family of solid carbon materials produced in a clean and controlled manner. Plasma pyrolysis of methane generates multi-form solid carbon whose structural and surface properties can be adjusted through process conditions.
These results demonstrate the capability of HyPlasma® to deliver a spectrum of advanced carbon materials from a single, combustion-free process.
