  2. Lurgi–Ruhrgas process - Wikipedia

    en.wikipedia.org/wiki/Lurgi–Ruhrgas_process

    The Lurgi–Ruhrgas process is a hot recycled solids technology, which processes fine particles of coal or oil shale sized 0.25 to 0.5 inches (6.4 to 12.7 mm). As a heat carrier, it uses spent char or spent oil shale (oil shale ash), mixed with sand or other more durable materials.

  3. Biological methanation - Wikipedia

    en.wikipedia.org/wiki/Biological_methanation

    This process can be applied in a power-to-gas system to produce biomethane and is appreciated as an important storage technology for variable renewable energy in the context of energy transition. [1] This technology was successfully implemented at a first power-to-gas plant of that kind in the year 2015.

  4. Biodiesel production - Wikipedia

    en.wikipedia.org/wiki/Biodiesel_production

    Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products. The fats and oils react with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight.

  5. Coal gas - Wikipedia

    en.wikipedia.org/wiki/Coal_gas

    Gasification is the process of subjecting a feedstock to chemical reactions that produce gas. [10] [11] The first process used was the carbonization and partial pyrolysis of coal. The off gases liberated in the high-temperature carbonization of coal in coke ovens were collected, scrubbed and used as fuel.

  6. Lurgi - Wikipedia

    en.wikipedia.org/wiki/Lurgi

    Lurgi can refer to: . Lurgi AG : The German Chemical and construction company; the Lurgi process for making gas from carbonaceous fuel under high pressure; Lurgi generator - a device used to produce gas from coal (see Gasification)

  7. Direct methanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Direct_methanol_fuel_cell

    Methanol cross-over and/or its effects can be alleviated by (a) developing alternative membranes (e.g. [6] [7]), (b) improving the electro-oxidation process in the catalyst layer and improving the structure of the catalyst and gas diffusion layers (e.g. [8]), and (c) optimizing the design of the flow field and the membrane electrode assembly ...

  8. Gas to liquids - Wikipedia

    en.wikipedia.org/wiki/Gas_to_liquids

    Methanol is made from methane (natural gas) in a series of three reactions: Steam reforming CH 4 + H 2 O → CO + 3 H 2 Δ r H = +206 kJ mol −1 Water shift reaction CO + H 2 O → CO 2 + H 2 Δ r H = -41 kJ mol −1 Synthesis 2 H 2 + CO → CH 3 OH Δ r H = -92 kJ mol −1. The methanol thus formed may be converted to gasoline by the Mobil ...

  9. Methanol - Wikipedia

    en.wikipedia.org/wiki/Methanol

    Methanol is primarily converted to formaldehyde, which is widely used in many areas, especially polymers. The conversion entails oxidation: 2 CH 3 OH + O 2 → 2 CH 2 O + 2 H 2 O. Acetic acid can be produced from methanol. The Cativa process converts methanol into acetic acid. [35] Methanol and isobutene are combined to give methyl tert-butyl ...
