  2. Methanol economy - Wikipedia

    en.wikipedia.org/wiki/Methanol_economy

    Currently the efficiency for hydrogen production by water electrolysis of electricity amounts to 75 to 85% [19] with potential up to 93% until 2030. [25] Efficiency for methanol synthesis of hydrogen and carbon dioxide currently is 79 to 80%. [19] Thus the efficiency for production of methanol from electricity and carbon dioxide is about 59 to 78%.

  3. Reformed methanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Reformed_methanol_fuel_cell

    The fuel cartridge stores the methanol fuel. Depending on the system design either 100% methanol (IMPCA industrial standard) or a mixture of methanol with up to 40 vol% water is usually used as fuel for the RMFC system. 100% methanol results in lower fuel consumption than water-methanol mixture (Premix) but goes along with higher fuel cell system complexity for condensing of cathode moisture.

  4. Methanol reformer - Wikipedia

    en.wikipedia.org/wiki/Methanol_reformer

    A mixture of water and methanol with a molar concentration ratio (water:methanol) of 1.0 - 1.5 is pressurized to approximately 20 bar, vaporized and heated to a temperature of 250 - 360 °C. The hydrogen that is created is separated through the use of Pressure swing adsorption or a hydrogen-permeable membrane made of polymer or a palladium alloy.

  5. Direct methanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Direct_methanol_fuel_cell

    Methanol and water are adsorbed on a catalyst usually made of platinum and ruthenium particles, and lose protons until carbon dioxide is formed. As water is consumed at the anode in the reaction, pure methanol cannot be used without provision of water via either passive transport such as back diffusion , or active transport such as pumping. The ...

  6. Methanol - Wikipedia

    en.wikipedia.org/wiki/Methanol

    Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...

  7. Carbon Recycling International - Wikipedia

    en.wikipedia.org/wiki/Carbon_Recycling_International

    The plant recycles approximately 150,000 tons of carbon dioxide and 20,000 tons of hydrogen from waste streams at the nearby petrochemical complex, producing 100,000 tons of low-carbon methanol annually. This methanol produced at this facility is used to manufacture polymers and plastics, including EVA coatings for solar panels and plexiglass ...

  8. Alcohol fuel - Wikipedia

    en.wikipedia.org/wiki/Alcohol_fuel

    Methanol and ethanol can both be derived from fossil fuels, biomass, or from carbon dioxide and water. Ethanol has most commonly been produced through fermentation of sugars, and methanol has most commonly been produced from synthesis gas, but there are more modern ways to obtain these fuels. Enzymes can be used instead of fermentation.

  9. Methanol fuel - Wikipedia

    en.wikipedia.org/wiki/Methanol_fuel

    After removing hydrogen sulfide and carbon dioxide , which form as side products during the gasification step, methanol can be made using conventional methods. [15] This route can offer renewable methanol production from biomass at efficiencies up to 75%. [17] Production methods using carbon dioxide as a feedstock have also been proposed.
