This invention belongs to the field of
environmentally friendly fuel technology, specifically relating to a method for preparing a green, low-carbon, and highly efficient modified fuel for
alcohol-
hydrogen engines. This invention comprehensively improves fuel performance through a progressive synergistic architecture of a bio-
methanol platform – an
oxygen-containing
combustion-promoting
system – a stability barrier – and a low-energy-consumption blending path. Using bio-
methanol as a base, it optimizes
combustion by compounding with
oxygen-containing components such as 2-MTHF and DMM / MF, achieving rapid ignition, emission reduction, and
noise reduction. Phase behavior is regulated by
isobutanol and polyether-modified
silicon, achieving a reversible and
stable phase without the need for high-HLB surfactants, preventing deposition and gas lock. A four-fold
protective barrier is constructed using GMO and fluorinated silica polyethers, combined with
antioxidant synergy to achieve
corrosion resistance and
aging resistance. The process adopts a sequential design of front-end purification – mid-stage two-phase construction – and end-stage static mixing, achieving low-energy homogenization and ensuring storage, transportation, and
operational stability.
