Questions and Answers

Which process is involved in fuel, food, and chemicals production and distribution?

  • Steam reforming
  • Partial oxidation
  • Autothermal reforming
  • Syngas production (correct)

What is the combination of steam reforming and partial oxidation called?

  • Equilibrium yields
  • High and low temps
  • Autothermal reforming (correct)
  • Pre-reformer

What is the purpose of using a pre-reformer in the process?

  • To lower the steam/carbon ratio
  • To favor the equilibrium yields
  • To increase the temperature
  • To protect downstream catalyst (correct)
