methanation

Nickel can also be used, but tends to favor methane formation ("methanation").

The advantage of this technique over selective methanation is the higher space velocity, which reduces the required reactors size.

The following main process describes the methanation:

The second involves combining hydrogen with carbon dioxide via a methanation process to produce synthetic natural gas prior to introduction to the grid.

Methanation is the reverse reaction of steam methane reforming, which converts methane into synthesis gas.

Methanation reaction converts syngas to synthetic natural gas (SNG).

Methanation is a physical-chemical process to generate Methane from a mixture of various gases out of biomass fermentation or thermo-chemical gasification.

The production process of SNG at the Great Plains plant involves gasification, gas cleaning, shift and methanation.

High prices of oil and natural gas are leading to increased interest in "BTU Conversion" technologies such as gasification, methanation and liquefaction.

The final step in producing the hydrogen is to use catalytic methanation to remove any small residual amounts of carbon monoxide or carbon dioxide from the hydrogen:

The process utilizes a specially designed reactor and depends upon a proprietary metal catalyst to promote chemical conversion at the low temperatures where the water gas shift reaction and methanation take place.

In the second stage, the syngas is converted into light hydrocarbons using one of three main processes: Fischer-Tropsch synthesis, Methanol synthesis with subsequent conversion to gasoline or petrochemicals, and methanation.

Hydrogen is added to the fuel mix during the gasification process, and Carbon Dioxide is removed by capture from the purge gas 'slip stream' Syngas clean-up and catalytic methanation stages.

The gas market and infrastructure the natural gas has contributed with is a condition for large scale introduction of renewable biomethane produced through anaerobic digestion (biogas) or gasification and methanation Bio-SNG.

The steam reforming, shift conversion, carbon dioxide removal and methanation steps each operate at absolute pressures of about 25 to 35 bar, and the ammonia synthesis loop operates at absolute pressures ranging from 60 to 180 bar depending upon which proprietary design is used.

One of these is the methanation reaction which occurs over a nickel metal catalyst and which was originally discovered by Sabatier and Senderens 80 years ago, Although this is widely used to make synthetic natural gas for example, there is even more interest in the production of compounds containing higher numbers of carbon atoms.
