25 — Biomethixon Fuel

Biologically Derived Methixon Synthetic Fuel

What It Is

Biomethixon Fuel is Hardin Labs' proprietary biogenic synthetic fuel — a molecular fuel blend derived from the methanol-pathway bioconversion of organic feedstocks, enhanced by catalytic reforming over a Silixon-PDC nano-catalyst substrate to produce a higher-energy, lower-emissions fuel with performance characteristics exceeding both conventional biodiesel and standard biomethanol. The "methixon" nomenclature designates the fuel's unique molecular composition: a methanol-based carrier upgraded with a fraction of linear and branched C8–C12 ethers produced during the Silixon-PDC catalytic reforming stage, giving the fuel a higher volumetric energy density than pure methanol while retaining its complete combustion to CO₂ and water.

Production Pathway

Biomethixon begins with the gasification or anaerobic digestion of organic waste — agricultural residue, municipal solid waste, or algal biomass — to produce syngas (CO + H₂) or biogas (CH₄ + CO₂). This syngas is fed to a copper-zinc oxide methanol synthesis catalyst to produce raw biomethanol. The biomethanol stream is then passed over a Silixon-PDC nano-catalyst packed bed at 350 °C, where the chromene-derived surface chemistry of the catalyst selectively oligomerizes a fraction of the methanol into C8–C12 ether molecules — the "methixon" component — while leaving the remaining methanol as the diluent carrier. The resulting Biomethixon blend has a volumetric energy density approximately 35% higher than pure methanol and an octane rating above 130, making it compatible with any high-compression spark-ignition engine without modification.

Applications

Biomethixon Fuel is the primary combustion fuel for the NVRT thruster's fuel-rich outer vortex ring during atmospheric operation, providing a carbon-neutral propellant source for the DART aircraft that eliminates dependence on petroleum jet fuel. It also serves as the backup fuel for the Silixon Battery charging generator on remote installations. Its full combustion to CO₂ and water — with zero soot, sulfur, or NOₓ byproduct — makes it the cleanest high-energy fuel available for turbine and rocket applications.
