SECTORS · CARBON PRODUCTION

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.

AN ALTERNATIVE ROUTE

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.

TECHNICAL FEATURES

What the analyses say.

Scanning electron microscope image of carbon black

High purity

Elemental analysis by Energy Dispersive Spectroscopy (EDS) 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.

Spectra showing the typical amorphous structure of carbon black

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 (Brunauer–Emmett–Teller) 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 N330 or N550, for liners, soles and engineering plastics.

Process flexibility

By adjusting operating parameters on our 100 kW pilot, 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.

BEYOND CARBON BLACK

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.
