Fischer–Tropsch process - Wikipedia

Synthesis gas obtained from coal gasification tends to have a H 2:CO ratio of ~0.7 compared to the ideal ratio of ~2. This ratio is adjusted via the water-gas shift reaction . Coal-based Fischer–Tropsch plants produce varying amounts of CO 2, depending upon the energy source of the gasification process.

Syngas Generation from Methane Using a Chemical-Looping .

Conversion of methane to syngas using a chemical-looping concept is a novel method for syngas generation. This process is based on the transfer of gaseous oxygen source to fuel (e.g., methane) by means of a cycling process using solid oxides as oxygen carriers to avoid direct contact between fuel and gaseous oxygen. Syngas is produced through the gas-solid reaction between methane and solid .
