SUMMARY

The process of creating methane (CH4) from hydrogen (H2) and carbon involves specific chemical reactions. The reaction 4H2 + CO2 = CH4 + 2H2O indicates that carbon dioxide can be utilized to produce methane when combined with hydrogen under appropriate conditions. The discussion emphasizes the necessity of heat and pressure to facilitate this reaction. The form of carbon used is crucial, as pure carbon in solid form may require different methods compared to carbon dioxide.

PREREQUISITES
  • Understanding of chemical reactions and stoichiometry
  • Knowledge of gas laws and conditions for reactions
  • Familiarity with the properties of hydrogen and carbon dioxide
  • Basic principles of thermodynamics related to heat and pressure
NEXT STEPS
  • Research the process of steam methane reforming (SMR)
  • Learn about the role of catalysts in methane production
  • Investigate the thermodynamic principles governing gas reactions
  • Explore alternative methods for methane synthesis, such as the Sabatier reaction
USEFUL FOR

Chemists, chemical engineers, and researchers interested in synthetic fuel production and the conversion of hydrogen and carbon into methane.

If you were given pure hydrogen and pure carbon what would you have to do to make methane?

Heat and pressure?

What form is your pure carbon in? If you meant pure carbon dioxide then maybe you could do 4H2 + CO2 = CH4 + 2H2O
