fueltuel

Fueltuel is a class of synthetic liquid hydrocarbon fuels intended to substitute conventional petroleum fuels in transport and power applications. It denotes fuels produced from non-petroleum feedstocks—such as municipal waste, biomass, plastics, natural gas, or coal—via gasification or pyrolysis to synthesis gas, followed by catalytic conversion (for example Fischer–Tropsch or hydroprocessing). The output is typically paraffinic hydrocarbons with controllable boiling ranges and high cetane or octane numbers.

Production involves gasification to synthesis gas, cleaning, catalytic conversion to longer-chain hydrocarbons, and refining to meet fuel specifications (density, sulfur, volatility). Fueltuels are designed to be drop-in replacements compatible with existing engines and fueling infrastructure, with tunable performance for diesel, gasoline, or aviation use.

Advantages include diverting waste from landfills, reducing crude-oil dependence, and enabling regional energy diversity. Environmental performance depends on feedstock and process energy; some pathways show lower life-cycle emissions when waste streams are used and energy inputs are managed carefully. The ability to tailor composition also allows alignment with local regulatory standards and ignition quality targets.

Key challenges are higher production costs, feedstock variability, and requirements for certification, safety testing, and infrastructure readiness. Regulatory acceptance varies by jurisdiction, and robust life-cycle analyses are required to quantify benefits and potential trade-offs.
